Safety Precautions

SAFETY FIRST

SAFETY FIRST!

This manual describes common test procedures used by experienced service

technicians. Many test procedures require precautions to avoid accidents that

can result in personal injury, and/or damage to your vehicle or test equipment.

Always read your vehicle's service manual and follow its safety precautions

before and during any test or service procedure. ALWAYS observe the following

general safety precautions:

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 the vehicle ONLY in a well-ventilated

area.

To protect your eyes from propelled objects as well as hot or caustic

liquids, always wear approved safety eye protection.

When an engine is running, many parts (such as the coolant fan,

pulleys, fan belt etc.) turn at high speed. To avoid serious injury,

always be aware of moving parts. Keep a safe distance from these

parts as well as other potentially moving objects.

Engine parts become very hot when the engine is running. To

prevent severe burns, avoid contact with hot engine parts.

Before starting an engine for testing or trouble-shooting, 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 suitable blocks.

Connecting or disconnecting test equipment when the ignition is ON

can damage test equipment and the vehicle's electronic com-

ponents. Turn the ignition OFF before connecting the Code Reader

to or disconnecting the Code Reader from the vehicle’s Data Link

Connector (DLC).

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.

The vehicle's battery produces highly flammable hydrogen gas. To

prevent an explosion, keep all sparks, heated items and open flames

away from the battery.

Don't wear loose clothing or jewelry when working on an engine.

Loose clothing can become caught in 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.

About the Car Reader

VEHICLES COVERED

The Car Reader is designed to work on all OBD 2 compliant vehicles. All 1996

and newer vehicles (cars and light trucks) sold in the United States are OBD 2

compliant. This includes all Domestic, Asian and European vehicles.

Some 1994 and 1995 vehicles are OBD 2 compliant. To find out if a 1994 or

1995 vehicle is OBD 2 compliant, check the following:

1. The Vehicle Emissions Control Information (VECI) Label. This label is

located under the hood or by the radiator of most vehicles. If the vehicle is OBD 2

compliant, the label will state “OBD II Certified.”

2. Government Regulations require that all OBD 2

compliant vehicles must have a “common”

sixteen-pin Data Link Connector (DLC).

Some 1994 and 1995 vehicles have 16-pin connectors but are not

OBD 2 compliant. Only those vehicles with a Vehicle Emissions Control

Label stating “OBD II Certified” are OBD 2 compliant.

Data Link Connector (DLC) Location

The 16-pin DLC is usually located under

the instrument panel (dash), within 12

inches (300 mm) of center of the panel,

on the driver’s side of most vehicles. It

should be easily accessible and visible

from a kneeling position outside the

vehicle with the door open.

On some Asian and European vehicles the DLC is located behind the

“ashtray” (the ashtray must be removed to access it) or on the far left

corner of the dash. If the DLC cannot be located, consult the vehicle’s

service manual for the location.

CODE RETRIEVAL PROCEDURE

Never replace a part based only on the DTC definition. Each DTC has a set of

testing procedures, instructions and flow charts that must be followed to confirm the

location of the problem. This information is found in the vehicle's service manual.

Always refer to the vehicle's service manual for detailed testing instructions.

Check your vehicle thoroughly before performing any test. See

Preparation for Testing on page 7 for details.

ALWAYS observe safety precautions whenever working on a vehicle.

See Safety Precautions on page 2 for more information.

1. Turn the ignition off.

2. Locate the vehicle's 16-pin Data Link Connector

(DLC). See page 3 for connector location.

3. Connect the Car Reader’s cable connector to the

vehicle's DLC. The cable connector is keyed and

will only fit one way.

■If you have problems connecting the cable

connector to the DLC, rotate the connector

180° and try again.

If you still have problems, check the DLC on

the vehicle and on the Car Reader. Refer to

your vehicle's service manual to properly check

the vehicle's DLC.

■After the Car Reader’s test connector is properly connected to the

vehicle's DLC, the Vehicle icon should display to confirm a good

power connection.

4. Turn the ignition on. DO NOT start the engine.

5. The Car Reader will automatically link to the vehicle’s computer.

■The LCD display will show "rEAd.” If the LCD

display is blank, it indicates there is no power

at the vehicle's DLC. Check your fuse panel

and replace any burned-out fuses.

If replacing the fuse(s) does not correct the

problem, see your vehicle's repair manual to

locate the proper computer (PCM) fuse/circuit.

Perform any necessary repairs before

continuing.

■After 4-5 seconds, the Car Reader will retrieve

and display any Diagnostic Trouble Codes that

are in the vehicle's computer memory.

■If an error message (Err, Err1 or Err2) is

shown on the Car Reader’s LCD display, it

indicates there is a communication problem.

This means that the Car Reader is unable to

communicate with the vehicle's computer. Do

the following:

E10

OBD2 9

Using the Car Reader

CODE RETRIEVAL PROCEDURE

-Turn the ignition key off, wait 5 seconds and turn the key back on to

reset the computer.

-Make sure your vehicle is OBD 2 compliant. See VEHICLES COVERED

on page 2 for vehicle compliance verification information.

6. Read and interpret the Diagnostic Trouble Codes using the LCD display and

the green, yellow and red LEDs.

The green, yellow and red LEDs are used (with the LCD display) as

visual aids to make it easier for the user to determine engine system

conditions.

■Green LED - Indicates that all engine

systems are "OK" and running normally. All

monitors on the vehicle are active and are

performing their diagnostic testing, and no

trouble codes are present. A zero will show on

the Car Reader’s LCD display for further

confirmation.

■Yellow LED - Indicates one of the following

conditions:

PENDING CODE PRESENT - If the yellow

LED is lit, it may indicate the existence of a

pending code. Check the Car Reader’s LCD

display for confirmation. A pending code is

confirmed by the presence of a numeric code

and the word PENDING on the Car Reader’s

LCD display. If no pending code is shown, the

yellow LED indicates Monitor Status (see the

following).

MONITOR STATUS - If the Car Reader’s LCD

display shows a zero (indicating there are no

DTCs present in the vehicle's computer), but

the yellow LED is lit, it indicates a "Monitor Has

Not Run" status. This means that some of the

Monitors on the vehicle have not yet finished

their diagnostic self-testing. This condition is

confirmed by one or more blinking Monitor

icons on the LCD display. A blinking Monitor

icon means the Monitor has not yet run and

finished its diagnostic self-testing. All Monitor

icons that are solid have completed their

diagnostic self-testing.

■Red LED - Indicates there is a problem with

one or more of the vehicle's systems. The red

LED is also used to show that DTC(s) are

present (displayed on the Car Reader’s LCD

display). In this case, the Multifunction Indicator

(Check Engine) lamp on the vehicle's instrument

panel will light steady on.

10 OBD2

Using the Car Reader

ERASING DIAGNOSTIC TROUBLE CODES (DTCs)

The Car Reader will automatically re-link to the vehicle's

computer every 15 seconds to refresh the data being retrieved.

When data is being refreshed, a single beep will sound, and

"rEAd" will be shown on the LCD display for 5

6 seconds. The

Car Reader will then beep twice and return to displaying codes.

This action repeats as long as the Car Reader is in com-

munication with the vehicle's computer.

The Car Reader will display a code only if codes are present in

the vehicle's computer memory. If no codes are present, a "0" will

be displayed.

7. If more than one code is present, press and release the SCROLL button,

as necessary, to display additional codes.

■Whenever the SCROLL function is used to view additional codes, the Car

Reader’s communication link with the vehicle's computer disconnects. To

re-establish communication, press the LINK button again.

Refer to page 14 for Diagnostic Trouble Code definitions. Match the retrieved

DTC(s) with those listed. Read the associated definition(s), and see the vehicle's

service manual for further evaluation.

ERASING DIAGNOSTIC TROUBLE CODES (DTCs)

When the Car Reader’s ERASE function is used to erase the DTCs

from the vehicle's on-board computer, "Freeze Frame" data and

manufacturer-specific enhanced data are also erased.

If you plan to take the vehicle to a Service Center for repair, DO NOT erase the

codes from the vehicle's computer. If the codes are erased, valuable information

that might help the technician troubleshoot the problem will also be erased.

Erase DTCs from the computer's memory as follows:

When DTCs are erased from the vehicle's computer memory, the I/M

Readiness Monitor Status program resets status of all the Monitors to

a not run "flashing" condition. To set all of the Monitors to a DONE

status, an OBD 2 Drive Cycle must be performed. Refer to your

vehicle's service manual for information on how to perform an OBD 2

Drive Cycle for the vehicle under test.

1. If not connected already, connect the Car Reader

to the vehicle's DLC. (If the Car Reader is already

connected and linked to the vehicle's computer,

proceed directly to step 4. If not, continue to step

2.)

2. Turn the ignition on. DO NOT start the engine. The

Car Reader will automatically link to the vehicle’s

computer.

E12

OBD2 11

Using the Car Reader

ERASING DIAGNOSTIC TROUBLE CODES (DTCs)

3. Press and release the Car Reader’s ERASE

button. The LCD display will indicate "SurE" for

your confirmation.

■If you change your mind and do not wish to

erase the codes, press the LINK button to

return to the code retrieval function.

■If you wish to continue, press the ERASE

button again. When all retrievable information,

including DTCs, has been cleared from the

computer’s memory, the Car Reader will re-link

to the vehicle’s computer, and the LCD display

will show "rEAd.”

Erasing DTCs does not fix the problem(s) that caused the code(s) to

be set. If proper repairs to correct the problem that caused the code(s)

to be set are not made, the code(s) will appear again (and the check

engine light will illuminate) as soon as the vehicle is driven long enough

for its Monitors to complete their testing.

DTC Definitions

DIAGNOSTIC TROUBLE CODE DEFINITIONS

Diagnostic Trouble Codes (DTCs) are meant to guide you to the proper service

procedure in the vehicle's service manual. DO NOT replace parts based only on

DTCs without first consulting the vehicle's service manual for proper testing

procedures for that particular system, circuit or component.

DTCs are alphanumeric codes that are used to identify a problem that is present

in any of the systems that are monitored by the on-board computer (PCM). Each

trouble code has an assigned message that identifies the circuit, component or

system area where the problem was found.

OBD 2 diagnostic trouble codes are made up of five characters:

■The 1st character is a letter. It identifies the "main system" where the fault

occurred (Body, Chassis, Powertrain, or Network).

■The 2nd character is a numeric digit. It identifies the "type" of code (Generic

or Manufacturer-Specific).

Generic DTCs are codes that are used by all vehicle manufacturers.

The standards for generic DTCs, as well as their definitions, are set by

the Society of Automotive Engineers (SAE).

Manufacturer-Specific DTCs are codes that are controlled by the

vehicle manufacturer. The Federal Government does not require

manufacturer-specific codes in order to comply with the new OBD 2

emissions standards. However, manufacturers are free to expand

beyond the required codes to make their systems easier to diagnose.

■The 3rd character is a numeric digit. It identifies the specific system or sub-

system where the problem is located.

■The 4th and 5th characters are numeric digits. They identify the section of

the system that is malfunctioning.

This section provides the most complete list of “Generic” DTC definitions

available at the time of publication. OBD 2 is an evolving system; new codes and

definitions are added as the system grows. ALWAYS check your vehicle's

service manual for code definitions that are not listed here, or for “Manufacturer-

Specific” DTC definitions. For more information, visit our web site at

www.CodeReader.com.
