17. Measure the resistance between the appropriate VSA modulator-control unit 46P connector wheel speed sensor +B and GND terminals (see
table), then measure the resistance between the same terminals after reversing the positive and negative tester probes.
Is the resistance infinity (ohmmeter may read OL) in both directions?
YES -
Go to step 18.
NO -
Go to step 20.
18. Disconnect the appropriate wheel speed sensor 2P connector See: Brakes and Traction Control/Antilock Brakes / Traction Control
Systems/Wheel Speed Sensor/Service and Repair.
19. On the sensor side, measure the resistance between appropriate wheel speed sensor 2P connector terminals No. 1 and No. 2, then measure
resistance between the same terminals after reversing the positive and negative tester probes.
Is the resistance infinity (ohmmeter may read OL) in both directions?
YES -
Replace the appropriate wheel speed sensor See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Wheel Speed
Sensor/Service and Repair.?
NO -
Repair an open in the wire between the appropriate wheel speed sensor and the VSA modulator-control unit.?
20. Check for continuity between the appropriate VSA modulator-control unit 46P connector wheel speed sensor +B and GND terminals (see
table), then check for continuity between the same terminals after reversing the positive and negative tester probes.
