Inspection and Verification

WARNING: This page is about a different car, the 2006 Ford Pickup, 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If a new ABS module is installed, it must be configured. Refer to MODULE CONFIGURATION .

Verify the customer concern.
Verify the stoplamps operate correctly by applying and releasing the brake pedal with the ignition switch in the OFF position. If the stoplamps do not operate correctly, refer to EXTERIOR LIGHTING . If the stoplamps operate correctly, proceed to the next step.

Visually inspect for obvious signs of mechanical or electrical damage.

If the cause is not visually evident, connect the scan tool to the data link connector (DLC) and select the vehicle to be tested from the scan tool menu. If the scan tool does not communicate with the vehicle:
- check that the program card is correctly installed.
- check the connections to the vehicle.
- check the ignition switch position.
If the scan tool still does not communicate with the vehicle, refer to scan tool operating manual.
Carry out the scan tool data link test. If the scan tool responds with:
- CAN, ISO or UBP circuit fault; all electronic control units no response/not equipped, refer to MODULE COMMUNICATIONS NETWORK .
- No response/not equipped for the ABS module, Go to PINPOINT TEST A .
- System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the ABS module.
If the DTCs retrieved are related to the concern, go to the ANTI-LOCK BRAKE SYSTEM (ABS) MODULE DIAGNOSTIC TROUBLE CODE (DTC) INDEX .
If no DTCs related to the concern are retrieved, Go to SYMPTOM CHART .

NOTE: Always retrieve the continuous DTCs after running the self-test.

NOTE: For a complete master list of DTCs, refer to MULTIFUNCTION ELECTRONIC MODULES .
