DTC 14

DTC 14: Wheel Sensor Pulse Signal

NOTE: The ABS indicator will go off when you test-drive the vehicle at 31 mph (50 km/h), if the indicator comes on for these reasons.
^ Only the drive wheel rotated
^ The vehicle spun
^ Electrical noise





1. Visually check for appropriate wheel sensor and purser installation and condition (see table).
Are they installed correctly and not damaged?
YES- Go to step 2.
NO- Reinstall or replace the appropriate wheel sensor or purser.
2. Disconnect the ABS control unit 31P connector.





3. Measure the resistance between the appropriate wheel sensor (+) and (-) circuit terminals of the ABS control unit 31P connector (see table).
Is there less than 450 Ohms?
YES- Repair short to wire between the appropriate wheel sensor (+) and (-) circuits.
NO- Go to step 4.





4. Check for continuity between the appropriate wheel sensor (+) circuit terminal and other wheel sensor (+) circuit terminals (see table).
Is there continuity?
YES- Repair short in the wires between the appropriate wheel sensor and the other wheel sensor harnesses.
NO- Clear the DTC, and test-drive the vehicle. If the ABS indicator comes on and the same DTC is indicated, replace the ABS modulator-control unit.
