Displaying Trouble Codes

Trouble codes appear in ascending (3-digit) numerical order and are prefixed by "P" (PCM), "I" (IPC), "A" (ACP), "R" (SIR), "T" (TCS) or "S" (RSS). A final digit of either a "C" (current) or "H" (history)" will also be indicated on every code. Diagnostic code level displays PCM codes first, followed by IPC, ACP, SIR, TCS or RSS codes (if so prompted).
For complete list of available PCM trouble codes, see PCM TROUBLE CODES table. If no codes are present for a system, a "NO X CODE" message (with X being system, i.e. "P", "I", etc.) will be displayed. If communication line to a component is not operating, a "NO X DATA" message will be displayed, indicating that IPC could not communicate with that system.
To continue with system diagnostics, see SERVICE MODE OPERATION. To exit from SERVICE MODE and go back to normal vehicle operation, depress AUTO or DEFOG button on CCC.
