Diagnostic Trouble Codes (DTCS) Display

To display the DTCs, the ignition must be in the "ON" position. The "OFF" and "WARMER" buttons of the Climate Control Center on digital IPCs, or the Climate Control Panel for Analog IPCs, are depressed until all the segments of the display are "ON". The Driver Information Center (DIC) will display the DTCs in the following manner:
1. All DTCs set. Each DTC will be displayed Along with its status, current or history.
2. The order of DTC display will be PCM, IPC, ACM, SDM, TCS, RSS, PZM, IRC, RFA, CCP, MSM, MMM and PHN (CCP, MSM, MMM and PHN will only appear on vehicles equipped with these options).
3. Depressing the FAN DOWN button will bypass DTC display.
