PINPOINT TEST G307559p2: C1145; RIGHT HAND FRONT WHEEL SPEED SENSOR (WSS) ELECTRICAL FAILURE

G307559t8: CHECK THE WSS TO ABS/DSC MODULE SIGNAL CIRCUIT FOR HIGH RESISTANCE
1. Turn the ignition switch to the OFF position.
2. Disconnect the ABS/DSC module electrical connector EC30.
3. Disconnect the WSS electrical connector EC15.
4. Measure the resistance between EC30, pin 34 (WU) and EC15, pin 02 (WU).

^ Is the resistance greater than 5 ohms?

-> Yes REPAIR the high resistance circuit. For additional information, refer to Vehicle/Diagrams. CLEAR the DTC. TEST the system for normal operation.

-> No GO to Pinpoint Test G307559t9.

G307559t9: CHECK THE WSS TO ABS/DSC MODULE SIGNAL CIRCUIT FOR SHORT TO GROUND
1. Measure the resistance between EC30, pin 34 (WU) and GROUND.

^ Is the resistance less than 10,000 ohms?

-> Yes REPAIR the short circuit. For additional information, refer to Vehicle/Diagrams. CLEAR the DTC. TEST the system for normal operation.

-> No GO to Pinpoint Test G307559t10.

G307559t10: CHECK THE WSS TO ABS/DSC MODULE SUPPLY CIRCUIT FOR HIGH RESISTANCE
1. Measure the resistance between EC30, pin 33 (NG) and EC15, pin 01 (NG).

^ Is the resistance greater than 5 ohms?

-> Yes REPAIR the high resistance circuit. For additional information, refer to Vehicle/Diagrams. CLEAR the DTC. TEST the system for normal operation.

-> No GO to Pinpoint Test G307559t2.

G307559t2: CHECK THE WSS TO ABS/DSC MODULE SUPPLY CIRCUIT FOR SHORT TO GROUND
1. Measure the resistance between EC30, pin 33 (NG) and GROUND.

^ Is the resistance less than 10,000 ohms?

-> Yes REPAIR the short circuit. For additional information, refer to Vehicle/Diagrams. CLEAR the DTC. TEST the system for normal operation.

-> No INSTALL a new right-hand front wheel speed sensor.
CLEAR the DTC. TEST the system for normal operation. If the DTC is repeated, contact dealer technical support for advice on possible ABS/DSC module failure.
