- 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.
- Clear the DTC (see page 19-90).

Does the ABS indicator come on and are DTCs 21, 22, 23, 24 indicated?
YES - Go to step 3.
NO - The system is OK at this time.
- Check the appropriate pulsar gear for a chipped tooth (see table).

Is the pulsar OK?
YES - Check for loose terminals in the ABS control unit 25P connector. If necessary, substitute a known-good ABS modulator control unit and recheck.
NO - Replace the driveshaft or the hub unit (Chipped tooth on pulsar gear).
