Read Codes

The Read Codes function retrieves Diagnostic Trouble Codes (DTCs) from the vehicles

computer modules. This function can be performed with the Key On-Engine Off (KOEO)

or Key On-Engine Running (KOER). Because DTCs indicate a circuit or system failure

(not component failures) they are very useful in isolating vehicle system malfunctions.

There are two types of codes, Malfunction Indicator Lamp (MIL) codes and Pending

codes. An icon (;) will be displayed next to DTCs that are Pending codes.

MIL Codes: These codes cause the computer to illuminate the MIL when an emis-

sion related or driveability fault occurs. The MIL is also known as the service engine

soon or check engine lamp. The computer illuminates the MIL when the engine is

running and the DTC remains in memory until the fault is repaired.
Pending Codes: These codes are also referred as continuous monitor and matur-

ing codes. An intermittent fault causes the computer to store a code in memory. If the

fault does not occur within 40 warm-up cycles, the code will be cleared from memory.

If the fault occurs a specific number of times, the code matures into a DTC and the

MIL turns on.

CAUTION!

Avoid Cooling Fan! It May

Turn On During Test.
