Diagnostic Code Display
- System will begin displaying codes (if any are stored). Codes will be displayed in order, beginning with PCM codes, and followed by IPC, ACM, SDM, TCS, RSS, PZM, IRC, RFA, CCP AND PHN. CCP and PHN codes will only appear if vehicle is equipped with system. See SYSTEM LETTER CODE INTERPRETATION table. Pressing FAN DOWN button will by-pass code display.
- The last character of the code is the letter "C" or "H". "C" stands for current code. Current means the fault currently exists (hard code), and the fault was present the last time the diagnostic test was run. "H" stands for history code. History means the fault does not currently exist, but existed before (intermittent code), and was not present the last time the diagnostic test was run.
