Anti-lock Brake System (ABS)/Traction Control and ABS/Traction Control with Advance Trac®/IVD Diagnostic Trouble Code (DTC) Index

NOTE: The need to recalibrate the module is indicated by the active/fail lamp flashing. There are other service actions that can require recalibration when there is no flashing lamp. The lamp will flash after clearing the DTCs that are indicated in the module calibration list.

NOTE: Always retrieve the continuous DTCs after running the self-test.

NOTE: For a complete master list of DTCs, refer to MULTIFUNCTION ELECTRONIC MODULES .

NOTE: DTC C1730 (Reference Voltage Out Of Range) must be repaired before DTC C1279, C1280, C1281, C1282, C1288, C1289.
