4. Check for continuity between the appropriate wheel sensor (+) circuit terminal and other wheel sensor (+) circuit terminals (see table).

DTC | Appropriate Terminal | Other Terminal
12 | No. 18 FRW (+) | No. 3 FLW (+) | No. 15 RRW (+) | No. 5 RLW (+)
14 | No. 3 FLW (+) | No. 18 FRW (+) | No. 15 RRW (+) | No. 5 RLW (+)
16 | No. 15 RRW (+) | No. 18 FRW (+) | No. 3 FLW (+) | No. 5 RLW (+)
18 | No. 5 RLW (+) | No. 18 FRW (+) | No. 3 FLW (+) | No. 15 RRW (+)

ABS CONTROL UNIT 25P CONNECTOR

Wire side of female terminals

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.

DTC 21, 22, 23, 24: Pulsar

1. Clear the DTC (see page 19-90).
2. Test-drive the vehicle at 19 mph (30 km/h) or more.

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.

3. Check the appropriate pulsar gear for a chipped tooth (see table).

   DTC | Appropriate Terminal
   21 | Right-front
   22 | Left-front
   23 | Right-rear
   24 | Left-rear

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).
