DTC 15: Wheel Speed Sensor Or Wiring Harness

Clear DTCs. See CLEARING CODES under DIAGNOSIS & TESTING. Recheck for DTCs after driving vehicle from a stop to faster than 6 MPH. If DTC 11, 12, 13 or 14 is displayed, perform DTCS 11, 12, 13 & 14: WHEEL SPEED SENSOR, SENSOR ROTOR, HYDRAULIC UNIT OR WIRING HARNESS test. If DTC 15 is displayed, go to next step. If DTC 11, 12, 13, 14 or 15 is not displayed, a temporary poor contact in wiring may have occurred and ABS is now functioning properly.
Check all wheel speed sensors. See WHEEL SPEED SENSORS under COMPONENT TESTING. Replace as necessary. If wheel speed sensors are okay, check wiring harness for open or short to ground between each wheel speed sensor and ABS control module. Repair wiring harness as necessary. If wiring harness is okay, replace ABS control module.
