Without Scan Tool

To enter diagnostics, proceed as follows:

1. Turn the ignition ON.

2. Push the OFF and WARM buttons on the Climate Control Panel simultaneously and hold until the segment check appears on the IPC and Combo Panel.

NOTICE: Operating the vehicle in diagnostics for extended time periods without the engine running or without a battery charger will cause the battery to run down and possibly relate false diagnostic information, or cause a no start condition. To ensure proper operation, attach a battery charger, if vehicle is to be operated in diagnostics without engine running for periods longer than 1/2 hour.

Segment Check

The purpose of illuminating the IPC, ECCP and DIC is to check that all segments of the liquid crystal displays are working. On the IPC however, the turn signal indicators do not light during this check. Further diagnosis should not be attempted unless all the ECCP and DIC segments appear, as this could lead to misdiagnosis. If any portions or segments of the ECCP or DIC display are inoperative, the Combo Panel must be replaced (if the entire display is blank, refer to Self-Diagnostic System Check).

Trouble Code Display

After diagnostics is entered, any trouble codes stored in computer memory will be displayed.

Each trouble code consists of the system abbreviation (P, L, B, R, T or S), a three digit code identifier, and the letter C or H. All codes for each system are displayed together, in the order of there three digit number (lowest first - i.e. S010, S011, etc.). The final digit of the code, a C or an H is used to indicate wether the code is current or history. C means the fault was still present the last time the diagnostic test was run, while H means the failure was not present the last time the code was tested for.
