Diagnostic Test

WARNING: This page is about a different car, the 2012 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. ABS VERIFICATION TEST 
    WARNING:

    To avoid possible serious or fatal injury, check brake capability is available before road testing.

    NOTE:

    If the Antilock Brake System (ABS) Module, Steering Angle Sensor (SAS), or the Dynamics Sensor was replaced, it must be initialized using the scan tool. If not initialized, the ABS indicator will flash continuously with no DTC's. To initialize the ABS Module and clear offsets have wheels pointing straight ahead and follow the directions on the scan tool. The drive test requires a 90° turn. If the Dynamics Sensor was replaced, test drive the vehicle by turning the vehicle left or right in a curving manner at a velocity between 10 and 25 km/h (6 and 15 mph).

    1. Turn the ignition off.
    2. Connect all previously disconnected components and connectors.
    3. Verify all accessories are turned off and the battery is fully charged.
    4. Verify that the ignition is on, with the scan tool, erase all Diagnostic Trouble Codes (DTC's) from All modules. Start the engine and allow it to run for two minutes and fully operate the system that was indicating the failure.
    5. Turn the ignition off and wait five seconds. Turn the ignition on and using the scan tool, read DTC's from all modules.
    6. If any Diagnostic Trouble Codes are present, Refer to ABS - DIAGNOSIS AND TESTING  and perform the diagnostic procedure.
    7. NOTE: For Sensor Signal and Pump Motor faults, the ABS Module must sense all 4 wheels at 12 km/h (7.5 mph) before it will extinguish the ABS indicator. 
    8. If there are no DTC's present after turning ignition on, road test the vehicle for at least five minutes. Perform several antilock braking stops.
    9. Again, with the scan tool read DTC's. If any DTC's are present, for the diagnostic procedure and troubleshoot the new or recurring DTC. Refer to ABS - DIAGNOSIS AND TESTING .
    10. If there are no Diagnostic Trouble Codes (DTC's) present, and the customer's concern can no longer be duplicated, the repair is complete.

      Are any DTC's present or is the original concern still present?

      Yes 

      No 

      • Repair is complete.
