SAFETY PRECAUTIONS

1 Chapter 1

SAFETY PRECAUTIONS

To avoid personal injury, instrument damage and/or damage to equipment under test; do not operate the Import Code Reader before reading this manual.

This manual describes common test procedures used by experienced service personnel and technicians. Many test procedures require precautions to avoid accidents that can result in personal injury, and/or vehicle or equipment damage. Always read your vehicle’s service manual and follow it’s safety precautions before any test or service procedure is performed.

a. When an engine is running, it produces carbon monoxide

(a toxic and poisonous gas). To prevent serious injury or death from carbon monoxide poisoning, operate a vehicle ONLY in a well-ventilated area.

b. To protect your eyes from propelled objects as well as hot

or caustic liquids, always wear approved safety eye protection.

c. When an engine is running, several objects rotate at a

very high rate of speed (electric cooling fans, pulleys, serpentine and fan drive belts, etc.). To avoid serious injury, always be conscious of moving parts, and keep a safe distance from all these items as well as other potentially moving objects.

d. Engine parts become extremely hot when the engine is

running. To prevent severe burns, avoid contact with hot engine parts.

e. Before starting an engine for troubleshooting, make sure

the parking brake is engaged. Put the transmission in “park” (for automatic transmission) or “neutral” (for manual transmission). Block the drive wheels with a suitable blocking device.

f. Connecting or disconnecting test equipment when the

ignition is “on” can cause a spark. This spark is potentially damaging to the test equipment and to the vehicle’s electronic components. Always turn the ignition “off” before connecting or disconnecting any test equipment.

g. To prevent damage to the on-board computer when taking

vehicle electrical measurements, always use a digital multimeter with at least 10 Megohms of impedance.

GENERAL INFORMATION

Chapter 1 2

h. The vehicle’s battery produces highly flammable hydrogen

gas. To prevent an explosion, keep all sparks, high temperature items or open flames away from the battery.

i. Do not wear loose clothing or jewelry when working on an

engine. Loose clothing can get caught on the fan, pulleys, belts, etc. Jewelry is highly conductive, and can cause a severe burn if it makes contact between a power source and ground.

GENERAL INFORMATION

This Code Reader and manual are designed for use both by consumers with little or no experience in retrieving codes, or by experienced technicians. If you are having problems with your vehicle and only want to know if any Diagnostic Trouble Codes are present in the vehicle’s computer system, go directly to Chapter 3 (for Honda/Acura), Chapter 4 (for Nissan/Infiniti) or Chapter 5 (for Toyota/Lexus), and follow the simple directions to retrieve the codes. The codes retrieved, and their definitions, will give you valuable information and a starting point from which to proceed to the next step.

Once the codes have been retrieved, you can choose to:

•

Take your vehicle to an Automotive Service Center for repair: Take your vehicle, a copy of the completed

Preliminary Vehicle Diagnosis Worksheet (see page 6) and diagnostic trouble codes retrieved to your technician for evaluation. This will demonstrate to your technician that you are an informed motorist and will also assist him in pinpointing the location of the problem.

•

AUTOMOTIVE COMPUTER CONTROL SYSTEMS

9 Chapter 2

AUTOMOTIVE COMPUTER CONTROL SYSTEMS

The main purpose of the vehicle’s Computer Control System is to provide maximum engine performance with the least amount of air pollution and the best fuel efficiency possible.

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 passenger side 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.

The on-board computer is the heart of the Computer Control System. The computer software contains several preprogrammed reference values that represent the ideal air/fuel mixture, spark timing, transmission gear selection, etc., for any driving condition. These values are programmed at the factory and are specific to each vehicle model.

The on-board computer receives information (inputs) from sensors and switches located throughout the engine. These devices monitor critical engine conditions (coolant temperature, engine speed, engine load, throttle position, air/fuel ratio, etc.). The computer compares the actual values received from these sensors with the reference values that are programmed in it’s memory. The computer commands the necessary corrections through operating output actuators as needed so that the incoming sensor values match the preprogrammed reference values for that particular driving condition.

Since vehicle operating conditions are constantly changing, the computer continuously makes adjustments or corrections (especially to the air/fuel mixture and spark timing) to keep all the engine systems operating within the pre-programmed reference values.

Page 13

About Import Vehicle Diagnostic Systems

ON-BOARD VEHICLE DIAGNOSTICS (OBD I)

Chapter 2 10

NOTE:

The computer does not make the adjustments or corrections directly. It commands other devices such as the fuel injectors, idle air control, EGR valve or Ignition Module to perform these functions. These devices are called Actuators because they initiate an action in response to the commands of the computer.

ON-BOARD VEHICLE DIAGNOSTICS (OBD I)

•

Beginning in 1988, California’s Air Resources Board (CARB), and later, the Federal Government's Environmental Protection Agency (EPA), required vehicle manufacturers to include a self diagnostic program capable of identifying an emissions-related fault via the vehicles On-Board Computers (some manufacturers used OBD before it was required). The first generation of Onboard Diagnostics came to be known as OBD I.

•

OBD I is a set of self-testing or self-diagnosing instructions that are programmed into the vehicle’s on-board computer.

•

The program is specifically designed to detect failures in the sensors, actuators, switches and wiring of the various vehicle emissions-related systems (fuel injection system, ignition system, EGR system, catalytic converter, etc.). If the computer detects a failure in any one of these components or systems, it alerts the driver by illuminating the “Check Engine” light on the dash.

•

The computer also assigns a numeric code (OBD I systems utilized a 2 or 3 digit code) for each specific problem that it detects, and stores these codes in it’s memory for later retrieval. The codes can be retrieved from the computer’s memory with the use of a device called a “Code Reader” or a “Scan Tool”.

NOTE:

With the exception of some 1994 and 1995 vehicles, most vehicles from about 1982 to 1995 are equipped with OBD I systems.

DIAGNOSTIC TROUBLE CODES

Diagnostic Trouble Codes, or Fault Codes, can be used to identify engine systems or components that are malfunctioning. The computer records codes for the following two types of engine problems:

Page 14

About Import Vehicle Diagnostic Systems

DIAGNOSTIC TROUBLE CODES

11 Chapter 2

•

“Hard” Codes. “Hard” codes are stored for problems

which are happening now. “Hard” codes cause the “Check Engine” light to turn on. The light remains on as long as the “hard” code is present.

•

“Intermittent” Codes. “Intermittent” codes are stored

for problems, which happened in the past but, are not currently present or detected by the vehicle’s computer. Intermittent problems may cause the “Check Engine” light to flicker by briefly turning on and turning off when the problem goes away. “Intermittent” codes stay in the computer’s memory even when the problem is no longer present. These intermittent problems may be caused by faulty wiring, vehicle operating conditions, etc.

NOTE:

Not all vehicles store “Intermittent” codes.

OVERVIEW OF HONDA/ACURA DIAGNOTIC SYSTEMS

13 Chapter 3

OVERVIEW OF HONDA/ACURA DIAGNOSTIC SYSTEMS

•

Retrieving codes from Honda/Acura vehicles requires the use of the two terminal connector of code retrieval tool as shown in Figure H1.

•

Honda/Acura vehicles use a variety of diagnostic systems which use either the “Check Engine” light or LEDs (Light Emitting Diodes) on the ECM (Engine Control Module) to display diagnostic trouble codes.

•

To retrieve codes you will need to access your vehicle’s computer test connector or ECM.

•

Honda/Acura vehicles use a rectangular two-socket plastic connector, usually light blue in color (H2).

NOTE:

Some Honda/Acura models do not require a tool to retrieve codes. The “Tool Req?” column in the “Code Retrieval Procedures Tables” on pages 14 through 17 will let you know if a tool is required. If no tool is required, just follow the procedures as indicated to retrieve codes.

“Check Engine” Light

•

The “Check Engine” light does more than alert you to a potential problem. It also transmits the fault codes in the computer’s memory through a series of blinks and pauses when the vehicle is in diagnostic mode.

•

Your “Check Engine” light is located on your vehicle’s instrument cluster, and may be labeled “PGM-FI”, “PGMCARB”, “CHECK”, or with a picture of an engine (Figure H3).

NOTE:

If your “Check Engine” light does not come on when you turn on the ignition, please refer to your vehicle’s service manual. You may have a problem with the vehicle that is preventing it from illuminating. You must fix this problem before you can retrieve fault codes from the vehicle’s computer.

ERASING CODES

•

Always observe safety precautions whenever working on a vehicle.

•

Remove Code Reader from vehicle’s test connector before erasing codes.

•

Erase codes only when all repairs have been completed. Refer to “Honda Erasing Procedures” or “Acura Erasing Procedures” for specific instructions for your year, make and model.

•

After erasing codes, verify that repairs were successfully completed. Start the engine and warm to normal operating temperature. After normal operating temperature is reached, turn off the ignition and repeat the code retrieval procedure for your vehicle. If no codes are retrieved, the repair(s) was successful.

NOTE:

Removing fuses or battery cables may clear the memory on the radio, clock, etc., or may enable the “Theftlock” feature on the radio.

HONDA/ACURA FAULT CODE DEFINITIONS

IMPORTANT:

Retrieving and utilizing Diagnostic Trouble Codes (DTCs) for troubleshooting vehicle operation problems is only one part of an overall diagnostic strategy. Never replace a part based solely on the DTC definition. Always consult the vehicle’s service manual for more detailed testing instructions. Each DTC has a set of testing procedures, instructions and flow charts that must be followed to confirm the exact location of the problem. This type of information is found in the vehicle’s service manual.

OVERVIEW OF NISSAN/INFINITI DIAGNOSTIC SYSTEMS

23 Chapter 4

OVERVIEW OF NISSAN/INFINITI DIAGNOSTIC SYSTEMS

•

Retrieving codes from Nissan/Infiniti vehicles requires the use of the flat end of the code retrieval tool shown in Figure N1.

•

Nissan/Infiniti vehicles use a variety of computer systems which are equipped with either a single-LED (Light Emitting Diode) or a dual-LED display.

•

To retrieve codes, you need to first locate the LED display on the vehicle’s computer. The LED(s) are mounted inside the computer, but may be seen by looking through an opening in the top of or on the side of the computer housing. In some cases you may have to remove the computer from its mount.

NOTE:

Refer to the vehicle’s service manual when removing the

computer from it’s mount, as it is easily damaged.

All Nissan/Infiniti vehicles covered in this manual are equipped with a screw-type diagnostic mode selector on the vehicle’s computer. The diagnostic mode selector is accessed through a cutout in the computer housing. Two marks show the operating limits of the diagnostic mode selector. The Code Reader is used to adjust the position of the diagnostic mode selector (N2).

NOTE:

Some Nissan/Infiniti models do not require a tool to retrieve codes. The “Tool Req?” column in the “Code Retrieval Procedures Tables” on pages 24 through 29 will let you know if a tool is required. If no tool is required, just follow the procedures as indicated to retrieve codes.
