DTC 13

ABS DTC 13: Wheel Sensor (Open/ Short to Body Ground/Short to Power)
1. Disconnect ABS/TCS control unit connector A (26P).
2. Start the engine.





3. Measure the voltage between the appropriate wheel sensor (+) circuit terminal and body ground (see table).
Is there 2V or more?
YES - Repair short to power in the (+) circuit wire between the ABS/TCS control unit and the appropriate wheel sensor.
NO - Go to step 4.





4. Check for continuity between the appropriate wheel sensor (+) circuit terminal and body ground (see table).
Is there continuity?
YES - Go to step 5.
NO - Go to step 6.
5. Disconnect the harness 2P connector from the appropriate wheel sensor, then check for continuity between the (+) and (-) terminals of the harness and body ground.
Is there continuity?
YES - Repair short to body ground in the (+) or (-) circuit wire between the ABS/TCS control unit and the wheel sensor.
NO - Replace the wheel sensor.





6. Check the resistance between the appropriate wheel sensor (+) and (-) circuit terminals (see table).
Is the resistance between 450 - 2,000 ohms?
YES - Check for loose ABS/TCS control unit connectors. If necessary, substitute a known-good ABS/TCS control unit, and rechecked
NO - Go to step 7.
7. Disconnect the harness 2P connector from the appropriate wheel sensor, and check the resistance between the (+) and (-) terminals of the wheel sensor.
Is the resistance between 450 - 2,000 ohms?
YES - Repair open in the (+) or (-) circuit wire, or short between the (+) circuit wire and the (-) circuit wire between the ABS/TCS control unit and the wheel sensor.
NO - Replace the wheel sensor.
