Trouble Code Display

After diagnostics is entered, any trouble codes stored in computer memory will be displayed. Codes may be stored for PCM, BCM, Lighting, SIR, ABS/TCS, or RTD systems. Each trouble code consists of system abbreviation ("P", "B", "V", "R", "T" or "S"), a three digit code identifier and letter "C" or "H".

All codes for each system are displayed together, in order of there three digit number (lowest first - i.e. P013, P014, etc.). The final digit of code, a "C" or an "H" is used to indicate whether code is current or history. "C" means fault was still present last time diagnostic test was run, while "H" means failure was not present last time code was tested for.

If no codes are present for a system, a NO X CODE message (with X being system i.e. PCM, BCM, SIR, ABS/TCS, or RTD) will be displayed. If communication line to a component is not operating, a NO X DATA message will be displayed, indicating that BCM could not communicate with that system. At any time during display of trouble codes, if RESET button on DIC is depressed system will exit Service Mode and go back to normal vehicle operation.
