ABS (With or Without Advance Trac and Stability Assist) Module Diagnostic Trouble Code (DTC) Index
WARNING: This page is about a different car, the 2003 Mercury Mountaineer and 2003 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
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:
DTC C1730 (Reference Voltage Out Of Range) must be repaired before DTC C1279, C1280, C1281, C1282, C1288, C1289.
