With Manufacturer's Scan Tool

Chrysler does not provide any trouble code number-driven diagnosis for this system. Testing information is provided for codes retrieved via the Chrysler Diagnostic Read Out Box (DRB) in code description text format only. ALLDATA Users have reported success using the code number with the description from the scan tool matching the description to diagnostic information listed.

1. Your diagnostic test procedure must begin with a thorough visual inspection of the ABS system for damaged components or disconnected connectors. The brake lamps must be operational and if they are not, repair them prior to continuing.
2. Connect the Diagnostic Readout Box (DRB), or equivalent scan tool, to the data link connector located under the dash to the right of the steering column. If the scan tool does not power up, check the power and ground supplies to the connector.
3. Select "Anti-lock Brakes". Turn the ignition on. If the scan tool displays "No Response", perform test 20-A. Test 20A - DRB "No Response" Message
4. Read and record all ABS Diagnostic Trouble Codes (DTCs). If the "CAB Power Feed Circuit" trouble code is present, it must be repaired prior the addressing any other DTCs. If any additional codes are present, proceed to the appropriate test.
5. If there are no trouble codes present, select "Inputs/Outputs" and read the brake switch input as you press and release the brake pedal.
- If the display does not match the state of the pedal, perform Test 18-A. Test 18A - ABS Warning Lamp
- If a problem with the yellow "ABS" warning lamp or the red "BRAKE" lamp exists, refer to the system tests below. Read the traction control switch input as you press and release the switch. If the display does not match the state of the lamp perform test 17-A. Test 17A - Stop Lamp Switch
6. If no other problems are found, it will be necessary to road test the vehicle. Perform several antilock stops from above 50 km/h (30 mph) and then repeat steps 2, 3, and 4. If any trouble codes are present, proceed to the appropriate test. Monitors, Trips, Drive Cycles and Readiness Codes
7. The following conditions should be considered "NORMAL" operation, and no repairs should be attempted to correct them.
- Brake pedal feedback during an ABS stop (clicking, vibrating)
- Clicking, groaning or buzzing at 12 km/h (7 mph) (drive off self test)
- Groaning noise during an ABS stop
- Slight brake pedal drop and pop noise when ignition is initially turned ON
- Brake pedal ratcheting down at the end of an ABS stop
8. If the complaint is ABS "cycling" at the end of a stop at low speeds, it may be caused by a marginal wheel speed sensor signal. The sensor air gap, tone wheel condition, and or brakes hanging up are possible causes to this condition.
