Stability Assist Module Diagnostic Trouble Code (DTC) Index
NOTE:
The need to recalibrate the stability assist module is indicated by the active/fail lamp flashing and the presence of DTC C1998. There are other service actions that can require recalibration when there is no flashing lamp. For additional information, refer to the STABILITY ASSIST CALIBRATION LIST 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.
