FAQ

X431 is a hi-tech product. With the development of modern automotive industry, more and more new technology will be adopted and there may be questions during operation. Read the user’s manual to get the answer whenever you have any question, or contact our Customer Service Center for help.

Here we list some frequently asked questions and answers relating to X431.

About Update via Internet

Question: “Removable Disk” icon does not

appear in the catalogue of “My computer” after the CF card reader/writer is connected to the USB port of computer. Why?

Answer: Possible cause: there may not be driver for CF

card reader/writer in the computer. The default driver is with the operating systems like Windows Me/2000/XP, Mac OS 9.x/Mac OS X and Linux 2.4.X. However, there is no such default driver with Windows 98.

Solution: Check if there is the driver for CF card reader/writer in the computer. If the computer uses Windows 98 operating system, it is necessary to install the driver into computer by using the CD-ROM provided with CF card reader/writer.

When the CF card reader/writer driver is installed successfully, a “Removable disk” icon will appear in the catalogue of “My computer”. Usually it is listed after original disk drive. For example, if there were drives A, B, C and D originally, the removable disk will be “E”. If there were drives A, B, C, D and E originally, the removable disk will be “F”. The rest may be deduced by analogy.

Question: Some downloaded diagnostic program is not listed in the update tool, what is the reason?

1. The downloaded diagnostic program is not put in the same folder as other diagnostic programs. Please move it to the same folder as others.

2. The diagnostic program is not fully downloaded. Please download the program again.

Question: When the updated software is used in vehicle diagnosis, some diagnostic program can not be downloaded successfully from the CF card. Why?

Answer: possible causes and solutions:

1. The Display Program may have not been updated. Please update the Display Program.

2. The diagnostic program for the vehicle make is damaged. Please re-download the diagnostic program and update.

Question: Why can’t the main unit recognize the replaced CF card?

Answer: There are two possible causes:

1. The original 32M CF card has not been fully copied. Please delete the incomplete file and copy again.

2. The CF card reader/writer is not compatible with the CF card. Monofunctional CF card reader/writer is better in such situation.

About ECU

In the last two decades, we have seen more and more extensive application of IT and electronic technologies in modern vehicles. Many vehicle control systems, typically EFI (Electronic Fuel Injection), ABS (Anti-block Braking System), SRS (Air Bag), TC (Traction Control), AT (Automatic Transmission), etc., are computerized. Computerization makes the control precisely, quickly, effectively and safely. Consequently, a significant progress in vehicle driveability, fuel economy, power performance, comfortability, emissions, safety and so on has been made.

Composition and Working Principle of ComputerControl System

The Computer Control System consists of the on-board computer, and several related control devices (sensors, switches, and actuators). Most on-board computers are located inside the vehicle behind the dashboard, under the passenger’s or driver’s seat, or behind the right kick panel. Some manufacturers may still position it in the engine compartment. The sensors, switches, and actuators are devices such as oxygen sensors, coolant temperature sensors, throttle position sensors, fuel injectors, etc., that are located throughout the engine, and are connected by electrical wiring to the on-board computer. As an example, the diagram of engine control system is shown in Figure 6-01.

Sensor

It is a device that converts non-electric variable into electric signal. More than 50 types of sensor are used in modern vehicles, most of which are found in powertrain, chassis control systems, body control system, safety system, etc.

According to the physical variables controlled, sensors are sorted into following types: temperature sensor, pressure sensor, air flow sensor, position/angular sensor, gas concentration sensor, rotary speed sensor, acceleration sensor, vibration sensor, light sensor, distance sensor, electrical current sensor, angular speed sensor, shaft sensor, liquid level sensor, etc.

The commonly-used sensors in corresponding control systems of vehicle are:

1) In engine management system: intake air pressure (or air flow), air/fuel ratio, crankshaft position, knock, RPM, intake air temperature, coolant temperature and O2 sensors.

2) In transmission system: vehicle speed, throttle position, RPM, A/T output shaft speed, toque, oil pressure/temperature, shift position sensors.

Figure 6-01

LAUNCH X-431 User’s Manual

3) In braking system: vehicle speed, wheel speed, deceleration, sliding rate, braking pedal force, braking pedal position sensors, etc.

4) In steering control system: steering, vehicle acceleration, vehicle speed sensors, etc.

5) In suspension system: vehicle speed, vehicle height, steering angle, throttle position, braking force sensors, etc.

6) In A/C system: external temperature, internal temperature, sunshine, coolant temperature, refrigerant pressure and humidity sensors, etc.

7) In instrument, alarm and diagnosis systems: remaining fuel, coolant temperature, oil pressure, oil status, intake air pressure, windshield washer fluid level, battery liquid level, door lock, braking fluid level sensors.

into electrical parameter.

2) A/D converter: it converts the analogue signal from the sensor into digital signal. Then the digital signal can get into SMC.

3) SMC: it consists of I/O interface, CPU, RAM/ROM, etc. The received digital signal is computed here with the pre-programmed parameters from ROM. The computed result is transmitted through I/O interface to the output circuit, and then to the corresponding actuators.

The data in ROM is written by manufacturer and will not be lost when power is off. However, the data in RAM will be lost when power is off.

4) Output circuit: it is to amplify the signal from SMC. The weak current from SMC is not able to activate the actuator. So it has to be amplified.

The electronic control unit is composed of input circuit, A/D converter, SMC, output circuit, etc. See Figure 6-02.

1) Input circuit: digital signal from sensor will enter the CPU directly. However, the analogue signal will be treated in the A/D converter before getting into CPU. The input circuit filters out the noise, converts sine wave into rectangular wave and then

Actuator

Actuator is to convert the electrical signal into force or displacement. The popular actuators are listed below:

1) Solenoid valve: This actuator is to convert electrical signal into linear movement. Two types of solenoid valves are used in the vehicle. One is directly driven with linkage, e.g. the magnetic switch of starter motor. The other is for controlling pressure and flow by transferring the movement to relevant valves. For example, in engine intake air control, electronically controlled automatic transmission, suspension control, etc.

2) Motor: DC motor is the most popular actuator used in automobile. It can be divided into two types according to its use. One is rotated by power, e.g. windshield wiper, seat adjuster, etc. The other is used in servo mechanism. In this situation, external force makes the rotor rotate around the stator, e.g. the servo motor for

damper.

Besides the two types listed above, there are other types, such as relay, electronic switch, etc.

Self-diagnosis of Electronic Control System

All modern cars are controlled by an Electronic Control Unit (ECU). The main purpose of the electronic control system is to provide maximum engine performance with the least amount of air pollution and the best fuel efficiency possible. However, the complexity of the system may increase the difficulty for its troubleshooting. The function of self-diagnosis is for solving such problem with electronic control system.

Working Principle of Self-diagnosis

The composition of self-diagnosis system is similar to electronic control system. The basic component is electronic control unit. The main purpose of self-diagnosis system is to diagnose the sensors, actuators, circuits and ECU in vehicle.

The computer assigns a numeric code for each specific problem that it detects, and stores these codes in its memory for later retrieval, and turns on the fault indicator on the dash panel to warn the driver. The problem detected may be: inputted/outputted signal exceeds the specified range, or some circuit is short-circuited or open.

Now let’s take gasoline injection control system as an example to describe the working principle of the self-diagnosis system. When problem occurs, the process of diagnosis and treatment will be as follows:

1) For sensor If the output signal from the sensor is out of the specified range of voltage when engine is running, it will be deemed as fault. For example, the normal output voltage from coolant temperature sensor should be in the range of

0.3-0.4V. If not, the situation will be deemed as

fault and fault code will be stored in memory. Self-diagnosis system can detect damaged sensor, or short/open circuit, but it can not appraise the performance of sensor. Occasional occurrence of abnormal signal will not be deemed as fault immediately. For not being interrupted by the sensor fault, the engine will be controlled by the pre-stored normal coolant temperature (e.g. 80℃) from the self-diagnosis

system.

2) For actuator

When the engine is running, ECU sends commands to actuators according to the practical situation. If the actuator can not work normally, the monitoring circuit will transmit the message to the ECU. ECU can make the message displayed and take measures to ensure the safe running of engine. For example, when the power tube in engine ignition system is out of order, the ignition monitoring circuit sends feedback to the ECU. ECU emits warning signal and sends commands to actuator for stopping injection so as to prevent the unburnt mixture from damaging the catalytic converter of exhaust system.

3) For ECU

There is no monitoring circuit, but a monitoring clock in the ECU for resetting ECU regularly. If ECU is out of order, its program will not be run and the clock will not reset the ECU so that overflow may occur. This situation is deemed as fault for displaying.

For preventing unexpected stopping of vehicle caused by problem with ECU, there is a backup circuit in ECU. When the backup circuit receives the signal of abnormality from the monitoring circuit, a spare control program will be started for keeping the engine running as pre-programmed.

Readout of Fault Code in Automotive Self-diagnosis System

The fault in vehicle electronic system is stored in KAM of ECU as fault code. The fault code can be read out by the on board diagnostic

LAUNCH X-431 User’s Manual

system or external scan tool. The on board diagnostic system in different

vehicle may indicate the fault in different way. In general, the following ways are popular:

1) Blinking of fault indicators on the instrument panel

2) Swing of multimeter index

3) Blinking of red/green LED on ECU

4) Shown by a special device

The more intuitionistic way for showing the fault is by external scan tool.

The diagnostic system of modern cars is equipped with diagnostic socket or DLC (data link connector). Fault code in vehicle ECU can be read out by connecting a scan tool to the diagnostic socket. In early time, each vehicle system had its own type of diagnostic socket. Since 1996, SAE has specified a uniform system called OBDII on board diagnostic system. Each vehicle that is made in accordance with the system may have the same diagnostic socket, same definition of pin and same description of fault code. The control units of every system are connected to bus, so only one diagnostic socket is needed for readout of fault code. OBD provides the possibility of reading data stream and displaying working status of switches and actuators. Moreover, external scan tool can send commands to activate the actuators.

X-431 is such an external scan tool for vehicle diagnosis. It not only has the diagnostic function like reading fault code, reading data stream, actuation test, displaying sensor waveform, coding control unit, etc., but also has PDA function.

Basic Knowledge of ECU

Composition of Vehicle ECU

Vehicle ECU consists of ALU, CPU, power source and memory.

1. ALU

It converts the electronic signal from each

sensor into digital signal needed by CPU.

2. CPU The digital signal is transferred to CPU for computation and logical operation so that correct air/fuel mixture can be obtained. CPU can also compute ignition timing and idle speed, and control exhaust, fuel and diagnostic systems.

3. Power source The reference output signal (5V) of ECU and the 12V voltage for control module are from vehicle battery. Memory is also dependent on the power supplied by the battery.

4. Memory ECU contains three types of memory: ROM, RAM and PROM (or EEPROM).

1) ROM ROM stores the programming information that can only be read by ECU. The program in ROM is not editable. Power cut will not damage the data in ROM.

2) RAM It is for temporarily storing the inputted data, fault code and computed result. Power cut will make all information in RAM erased.

3) PROM Its program is made by manufacturer to suit the application of transmission, engine, exhaust control, driveability, rear axle ratio, etc. PROM is can be detached from ECU and power cut will not damage the data in it.

4) EEPROM Its function is similar to PROM. The difference between EEPROM and PROM is that EEPROM can be re-programmed by manufacturer with a special device.

Precautions Related to ECU

The circuit inside the ECU is very accurate and may be easily damaged by overvoltage, static electricity and/or magnetic fields. Pay more attention when diagnosing the devices that is

LAUNCH X-431 User’s Manual

connected to ECU because most ECU’s are operated under low voltage (about 5V).

Whenever you work in the vicinity of ECU or engine control system, please obey the following precautions:

1. Never damage the lead or connector.

Prevent them from being grounded or contacting with an unexpected power source.

2. Never use the electrical test tool that is

powered by 6V battery or over. Strong current may cause the element in ECU broken or shorted. For checking the engine control circuit, only the multimeter with large internal impedance (over 10MΩ) can be used.

3. Never try to disassemble or repair ECU if

there are not necessary tools and information. Any mistake may damage the component or increase the difficulty for service station.

4. The spark plug wire must be at least 25.4mm

from any sensor circuit or control circuit. Some unexpected fault in ECU circuit is caused by magnetic fields that transmit wrong signal to ECU. High tension wire or transformer may interfere with ECU, but the most common cause for such problem is that the spark plug is too close to ECU harness.

5. Be careful when moving ECU or working

around ECU. Remember that static electricity may cause strong electrical shock and damage ECU.

Appendix 1: about VIN

VIN is the abbreviation of Vehicle Identification Numbers.

A car’s vehicle identification number (VIN) is the identifying code for your SPECIFIC automobile. It is your car's fingerprint.

It sets your vehicles apart from the millions of vehicles out there. Recently the VIN is reflected by 17 digit characters. It displays a car’s uniqueness and manufacturer and provides a method to trace your car from the factory to the junk yard.

Each character or digit has a particular purpose. They are as follows:

l First vehicle identification number digit

identifies the country from which the vehicle was manufactured. For example, U.S.A.(1 or 4), Canada (2), Mexico (3), Japan (J), Korea (K), England (S), Germany (W), Italy (Z).

l Second vehicle identification number digit

specifies the manufacturer. Audi (A), BMW (B), Buick (4), Cadillac (6), Chevrolet (1), Chrysler (C), Dodge (B), Ford (F), GM Canada (7), General Motors (G), Honda (H), Jaguar (A), Lincoln (L), Mercedes Benz (D), Mercury (M), Nissan (N), Oldsmobile (3), Pontiac (2 or 5), Plymouth (P), Saturn (8), Toyota (T), Volvo (V).

l Third vehicle identification number digit

indicates the vehicle type or manufacturing division.

l Fourth through eighth vehicle identification

number digit reveals the vehicle features such as body style, engine type, model, series, etc.

l The ninth vehicle identification number digit

is a VIN accuracy check digit, verifying the previous VIN numbers. This is how the check digit works:

♦ STEP 1

Assign to each number in the VIN its actual mathematical value and assign to each letter the value specified for it in the following chart:

ASSIGNED VALUES: A=1 G=7 P=7 X=7 B=2 H=8 R=9 Y=8 C=3 J=1 S=2 Z=9 D=4 K=2 T=3 E=5 M=3 U=4 F=6 N=4 V=5

♦ STEP 2

Multiply the assigned value for each character in the VIN by the position weight factor specified in the following chart:

VIN POSITION AND WEIGHT FACTOR: 1st = 8 10th = 9 2nd = 7 11th = 8 3rd = 6 12th = 7 4th = 5 13th = 6 5th = 4 14th = 5 6th = 3 15th = 4 7th = 2 16th = 3 8th = 10 17th = 2 9th = check digit

♦ STEP 3

Add the products from steps 1 and 2 and divide the total by 11.

♦ STEP 4

The numerical remainder is the check digit which would appear in the 9th position in the VIN. If the remainder is 10, then the letter "X" is used for the check digit.

l Tenth vehicle identification number digit

tells the model year. 1988 (J), 1989 (K), 1990 (L), 1991 (M), 1992 (N), 1993 (P), 1994 (R), 1995 (S), 1996 (T), 199 7(V), 1998 (W), 1999 (X), 2000 (Y)------2001(1), 2002 (2), 2003 (3)

LAUNCH X-431 User’s Manual

l Eleventh vehicle identification number digit

reveals the assembly plant for the vehicle.

l The twelfth to seventeenth vehicle

identification number digits indicate the sequence of the vehicle for production as it rolled of the manufacturers’ assembly line.

Your VIN can be used to track recalls, registrations, warranty claims, thefts and insurance coverage.

Common locations of the vehicle identification number (VIN) vary but the following are places to look:

l Firewall of the vehicle l Left hand inner wheel arch l Steering column l Radiator Support Bracket l Dash by windshield l Drivers door or post on passenger side l Guarantee & Maintenance Book *Vehicle

documents

l Machined Pad on front of engine l Component parts as listed above -eg-

engine, frame, etc.
