Dakota Quad Cab 4WD V6-3.9L VIN X (2001)
The CAB contains a self check program that illuminates the ABS warning light when a system fault is detected. Faults are stored in a diagnostic
program memory and are accessible with the DRB scan tool.
ABS faults remain in memory until cleared, or until after the vehicle is started approximately 50 times. Stored faults are not erased if the battery is
disconnected.
