Stability Assist ABS Module Diagnostic Trouble Code (DTC) Index
NOTE:
The need to recalibrate the stability assist module is indicated by the active/fail lamp flashing. There are other service actions that can require recalibration when there is no flashing lamp. Refer to the ABS MODULE CALIBRATION (ABS WITH STABILITY ASSIST) . The lamp will flash after clearing the DTCs that are indicated on the STABILITY ASSIST CALIBRATION LIST .
NOTE:
DTC C1730 (Reference Voltage Out Of Range) must be repaired before DTC C1279, C1280, C1281, C1282, C1288, C1289.
