DTC 11, 13, 15 & 17: Wheel Sensor Circuit Open Or Shorted

Disconnect ABS control unit 22-pin connector. Start engine. Using DVOM connected to ground, measure voltage at appropriate terminal of ABS control unit connector as follows:
- DTC 11
  
  Terminal No. 9 (Green/Black wire) for right front wheel.
- DTC 13
  
  Terminal No. 7 (Green/Orange wire) for left front wheel.
- DTC 15
  
  Terminal No. 19 (Green/Yellow wire) for right rear wheel.
- DTC 17
  
  Terminal No. 17 (Light Blue wire) for left rear wheel.
See Figure. If voltage is 2 volts or more, check for short to power in wiring between ABS control unit and appropriate wheel speed sensor. See WIRING DIAGRAMS . If voltage is less than 2 volts, go to next step.
Using DVOM, check ABS control unit terminal listed in previous step for continuity to ground. If continuity does not exist, go to next step. If continuity exists, check wiring between ABS control unit and wheel speed sensor for short to ground. See WIRING DIAGRAMS . If harness is okay, check wheel speed sensor for a short to ground. Repair or replace as necessary.
Check for open in affected wheel speed sensor circuit by measuring resistance between appropriate terminals of ABS control unit 22-pin connector terminals as follows:
- DTC 11
  
  Terminal No. 9 (Green/Black wire) and terminal No. 8 (Green wire) for right front wheel.
- DTC 13
  
  Terminal No. 7 (Green/Orange wire) and terminal No. 6 (Light Green/Black wire) for left front wheel.
- DTC 15
  
  Terminal No. 19 (Green/Yellow wire) and terminal No. 20 (Blue/Yellow wire) for right rear wheel.
- DTC 17
  
  Terminal No. 17 (Light Blue wire) and terminal No. 18 (Gray wire) for left rear wheel.
See Figure. At 68°F (20°C), resistance should be 450-2050 ohms for any wheel speed sensor circuit. If resistance is as specified, check for poor terminal contact at ABS control unit. If connection was okay, replace ABS control unit. If resistance is not as specified, check circuit wiring for any opens or shorts. See WIRING DIAGRAMS . If circuit wiring is okay, replace wheel speed sensor.
