Stability Assist Module Diagnostic Trouble Code (DTC) Index

NOTE: The need to recalibrate the stability assist module is indicated by the "TRAC OFF" and "TRAC ACTIVE" lamps flashing. There are other service actions that may require recalibration where there is no flashing lamp. Refer to STABILITY ASSIST MODULE CALIBRATION . The lamp will flash after the clearing of DTCs that are indicated on the stability assist calibration list.
NOTE: Stability assist may be referred to as interactive vehicle dynamics (IVD) in the diagnostic tool.
NOTE: DTC C1730 (Reference Voltage Out Of Range) must be repaired before DTC C1279, C1280, C1281, C1282, C1288, C1289.
