Dakota 4WD V6-3.9L VIN X (1997)
ABS Light: Testing and Inspection
The diagnosis found here addresses an inoperative Anti-lock Brake System (ABS) lamp condition. If the ABS lamp stays on with the ignition switch in
the On position, or comes on and stays on while driving, refer to Brakes and Traction Control/Brakes/Anti-Lock Brakes for diagnosis.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.
FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIR-BAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.
If the ABS lamp fails to light when the ignition switch is turned to the On position, replace the ABS lamp bulb with a known good unit. If the ABS lamp
still fails to operate, diagnosis of the ABS system and the Chrysler Collision Detection (CCD) data bus should be performed with a DRB scan tool as
described in the proper Diagnostic Procedures. For diagnosis of the ABS lamp and the instrument cluster circuitry, see Instrument Panel, Gauges and
Warning Indicators/Instrument Panel/Instrument Cluster.
Rear Wheel Anti-Lock Brake System Lamp
The diagnosis found here addresses an inoperative Rear Wheel Anti-Lock (RWAL) brake system lamp condition. If the RWAL lamp stays on with the
ignition switch in the On position, or comes on and stays on while driving, refer to Brakes and Traction Control/Brakes/Anti-Lock Brakes for
diagnosis. If no RWAL system problem is found, the following procedure will help locate a short or open in the RWAL lamp circuit.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR
SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIR-BAG DEPLOYMENT AND
POSSIBLE PERSONAL INJURY.
1. Check the fuse in the junction block. If OK, go to Step 2. If not OK, repair the shorted circuit or component as required and replace the faulty fuse.
2. Turn the ignition switch to the On position. Check for battery voltage at the fuse in the junction block. If OK, go to Step 3. If not OK, repair the
open circuit to the ignition switch as required.
3. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Remove the instrument cluster bezel and the cluster
as described. Unplug the wire harness connector from the RWAL Controller Anti-lock Brake (CAB). Check for continuity between the RWAL
indicator control circuit cavity of the CAB wire harness connector and a good ground. There should be no continuity. If OK, go to Step 4. If not
OK, repair the short circuit as required.
4. Check for continuity between the HWAL indicator control circuit cavities of the CAB wire harness connector and the cluster wire harness
connector. There should be continuity. If OK, replace the faulty bulb. If not OK, repair the open circuit as required.
