2008 Mazda Tribute s Sport, 4WDSECTION Inspection and Verification
NOTE:
- If a new anti-lock brake system (ABS) module or hydraulic control unit (HCU) is installed, it must be configured. Follow the scan tool directions.
- 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, see STOPLAMPS . If the stoplamps operate correctly, proceed to the next step.
- Verify that the PRNDL operates correctly on the instrument cluster. If the PRNDL does not operate correctly, see INSTRUMENT CLUSTER . If the PRNDL operates correctly, proceed to the next step.
- Visually inspect for obvious signs of mechanical or electrical damage.VISUAL INSPECTION CHART

- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the cause is not visually evident, connect the scan tool to the data link connector (DLC).NOTE:
- Make sure to use the latest scan tool software release.
- If the scan tool does not communicate with the VCM:
- check the VCM connection to the vehicle.
- check the scan tool connection to the VCM.
- See PINPOINT TEST 14: NO POWER TO THE SCAN TOOL to diagnose no communication with the scan tool.
NOTE:- The vehicle communication module (VCM) LED prove out confirms power and ground from the DLC are provided to the VCM.
- If the scan tool does not communicate with the vehicle:
- verify the ignition key is in the ON position.
- verify the scan tool operation with a known good vehicle.
- See PINPOINT TEST 1: THE PCM DOES NOT RESPOND TO THE SCAN TOOL OR NO HIGH SPEED CONTROLLER AREA NETWORK (HS-CAN) COMMUNICATION to diagnose no response from the PCM.
- Carry out the network test.
- If the scan tool responds with no communication for one or more modules, see SYMPTOM TROUBLESHOOTING CHART - COMMUNICATIONS NETWORK .
- If the network test passes, retrieve and record continuous memory DTCs.
- Clear the continuous DTCs and carry out the self-test diagnostics for the ABS module.NOTE:
- The vehicle must be at a complete standstill while carrying out the self-test. Any movement of the vehicle during the self-test may result in false DTCs being set.
- If the DTCs retrieved are related to the concern, go to ABS Module DTC Chart. See ANTI-LOCK BRAKE SYSTEM (ABS) DTC CHART . For all other DTCs, see DIAGNOSTIC TROUBLE CODE (DTC) CHART - B, C AND U CODES .
- If no DTCs related to the concern are retrieved, see SYMPTOM TROUBLESHOOTING CHART - ANTI-LOCK BRAKE SYSTEM (ABS)
.NOTE:
- Always retrieve the continuous DTCs after running the self-test.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
