Precautions on Using X-431 Throttle
Before using this test equipment, please read the following safety information
carefully.
Always perform automotive testing in a safe environment.
y
If the diagnostic connector remains unused for a long period of time, it is
y
suggested to unplug the connector from vehicle’s DLC to conserve battery
power.
Wear an ANSI-approved eye shield when testing or repairing vehicles.
y
The vehicle shall be tested in a well-ventilated work area, as engines produce
y
various poisonous compounds (hydrocarbon, carbon monoxide, nitrogen
oxides, etc.)
Do not connect or disconnect any test equipment while the ignition is on or
y
the engine is running.
Put blocks in front of the drive wheels and never leave the vehicle unattended
y
while testing.
Keep the test equipment dry, clean, free from oil, water or grease. Use a mild
y
detergent on a clean cloth to clear the outside of the equipment as
necessary.
Do not drive the vehicle and operate the test equipment at the same time.
y
Any distraction may cause an accident.
Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or
y
hot engine parts.
Before starting the engine, put the gear lever in the Neutral position (for
y
manual transmission) or in the Park (for automatic transmission) position to
avoid injury.
To avoid damaging the test equipment or generating false data, please make
y
sure the vehicle battery is fully charged and the connection to the vehicle
DLC (Data Link Connector) is clear and secure.
Automotive batteries contain sulfuric acid that is harmful to skin. In operation,
y
direct contact with the automotive batteries should be avoided. Keep the
ignition sources away from the battery at all times.
Precautions on Operating Vehicle’s ECU
Do not disconnect battery or any wiring cables in the vehicle when the ignition
y
switch is on, as this could avoid damage to the sensors or the ECU.
Do not place any magnetic objects near the ECU. Disconnect the power
y
supply to the ECU before performing any welding operations on the vehicle.
iii

5.5 I/M Readiness
An important part of a vehicle’s OBD II system is the Readiness Monitors, which
are indicators used to find out if all of the emissions components have been
evaluated by the OBD II system. They are running periodic tests on specific
systems and components to ensure that they are performing within allowable
limits.
Currently, there are eleven OBD II Readiness Monitors (or I/M Monitors) defined
by the U.S. Environmental Protection Agency (EPA). Not all monitors are
supported in every vehicles and the exact number of monitors in any vehicle
depends on the motor vehicle manufacturer’s emissions control strategy.
Continuous Monitors -- Some of the vehicle components or systems are
continuously tested by the vehicle’s OBD II system, while others are tested only
under specific vehicle operating conditions. The continuously monitored
components listed below are always ready:
1）Misfire
2）Fuel System
3）Comprehensive Components (CCM)
Once the vehicle is running, the OBD II system is continuously checking the
above components, monitoring key engine sensors, watching for engine misfire,
and monitoring fuel demands.
Non-Continuous Monitors -- Unlike the continuous monitors, many emissions
and engine system components require the vehicle to be operated under
specific conditions before the monitor is ready. These monitors are termed
non-continuous monitors and are listed below:
1) EGR System
59
LAUNCH X-431 Throttle User Manual
2) O2 Sensors
3) Catalyst
4) Evaporative System
5) O2 Sensor Heater
6) Secondary air Injection
7) Heated Catalyst
8) A/C system
I/M refers to Inspection and Maintenance that is legislated by the Government to
meet federal clean-air standards. I/M Readiness indicates whether or not the
various emissions-related systems on the vehicle are operating properly and are
ready for Inspection and Maintenance testing.
The purpose of the I/M Readiness Monitor Status is to indicate which of the
vehicle’s Monitors have run and completed their diagnosis and testing, and
which ones have not yet run and completed testing and diagnosis of their
designated sections of the vehicle’s emissions system.
The I/M Readiness Monitor Status function also can be used (after repair of a
fault has been performed) to confirm that the repair has been performed
correctly, and/or to check for Monitor Run Status.
Tap [I/M Readiness] on the Job Menu to start checking. After checking all I/M
readiness status, the screen will output the result:

Simulation test enables users to exactly judge if the sensor is good or not to
avoid replacing components blindly. For example, the trouble code indicates the
fault is in water temperature sensor itself. But we need to confirm whether the
fault results from water temperature sensor or the connections between ECU
and sensors, or ECU itself. In this case, we can make full use of simulation test
to input the signal of simulating water temperature sensor, instead of water
temperature sensor, to the microcomputer. If the engine works better and the
fault vanishes, the fault is in the water temperature sensor. If the fault still occurs,
input the signal to the corresponding terminals of ECU. Consequently, if the fault
disappears, the fault lies in the connection between water temperature sensor
and ECU, otherwise, the fault exists in ECU.
After all connections are properly made (refer to Chapter 9.3.1 for details),
launch X-431 Throttle application and enter the Job menu interface, then tap
“Toolbox” -> “Sensor” to enter the test selection screen. See Fig. 9-2.

Knock sensor testing
(1) Resistance test for knock sensor
Switch ignition “OFF”, unplug the wire connector of knock sensor, test the
resistance between the wire terminal and the case of knock sensor with
“Resistance test” function, it shall be ∞ (disconnected), and if it is
0Ω(conductive), which means the knock sensor shall be replaced. For the
magnetostriction knock sensor, it can also test the resistance by the “Resistance
measurement” function; the resistance shall be compliant with the specified
value (see specific service manual for the detailed data), otherwise, the knock
sensor shall be replaced.
(2) Checking for the output signal of knock sensor
Unplug the wire connector of knock sensor, check voltage between knock
sensor connector terminal and ground wire of knock, it should be output pulse
voltage; otherwise, the knock sensor shall be replaced.
Coolant temperature sensor testing
(1) Resistance test for coolant temperature sensor
On vehicle testing:
Switch ignition “OFF” and unplug the wire connector of coolant temperature
sensor, then use the “Resistance measurement” to test the Resistance between
two terminals of sensor. The relationship between the resistance and the
temperature is in inversely proportion (negative temperature coefficient), which
shall be less than 1kΩ during warming up.
Independent testing:
Unplug the wire connector of coolant temperature sensor, then remove the
sensor from the engine; place the sensor into a breaker with water and heat the
water, then use the “Resistance measurement” to test the Resistance between
two terminals of coolant temperature sensor at different water temperature.
Compared the measured value with the standard value, if the Resistance is not

compliant with the standard, then the coolant temperature sensor shall be
replaced.
(2) Output signal voltage testing for coolant temperature sensor
After installing the coolant temperature sensor, plug the wire connector of
sensor, and then switch ignition ON, test the output signal voltage between the
two terminals of wire connector. The tested voltage shall be in inverse
proportional with the coolant temperature. When the harness of coolant
temperature sensor is disconnected, the voltage shall be about 5V if the ignition
switch is ON.

11.2 Test Environment
11.2.1 Test environment
Inside the vehicle test indicates that the battery connects to loading devices,
such as engine, etc. After doing battery test, it can perform charging system and
actuation system test, which is proceeded as a whole simultaneously. Charging
system and actuation system test is not required but must not be performed
before battery test. Because it is difficult for vehicle technicians to judge where is
faulty exactly if they have the faintest idea of battery’s status itself.
Outside the vehicle test indicates that the battery is disconnected from all
loading devices on vehicles. Therefore, only battery test is supported in this
condition.
11.2.2 Battery status and description
There are mainly 5 states as follows:
No. States Descriptions
1 Good battery Indicates battery is normal.
Indicates that battery is aged or becomes rejected, or
battery life cycle approaches to be exhausted. In this
2 Replace battery
3 Good-recharge Stands for low battery. The battery is good itself.
4 Charge-retest
5 Bad cell
case, battery voltage appears to be normal, but
battery itself is not well, i.e. battery polarity board has
been completely vulcanized or aged. Please replace
battery immediately.
It is better for a few batteries to be fully charged
before testing in order to avoid judging in error under
special conditions.
Indicates one of the battery cells is bad and cannot
work normally, but for which one is bad, it can’t be
verified. In this case, battery voltage is generally lower
than 11V, mainly resulting from internal circuitry
damage, such as short circuit, open circuit, dummy
weld etc.
