PINPOINT TEST G92304p4: DTC C1175, C1236; LEFT-HAND REAR WHEEL SPEED SENSOR (WSS) CIRCUIT FAILURE

G92304t33: CHECK THE LEFT-HAND REAR WSS SENSOR CIRCUIT FOR HIGH RESISTANCE

1. Make sure the ignition switch is in the OFF position.
2. Disconnect the ABS/DSC module electrical connector, JB45/JB185.
3. Disconnect the wheel speed sensor electrical connector, CA55.
4. Measure the resistance between CA55, pin 02 (WU) and JB45/JB185, pin 14 (WU).
^ Is the resistance greater than 5 ohms?

-> Yes
REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC, test the system for normal operation.

-> No
GO to Pinpoint Test G92304t34.

G92304t34: CHECK THE LEFT-HAND REAR WSS SENSOR CIRCUIT FOR SHORT CIRCUIT TO BATTERY

1. Measure the voltage between CA55, pin 02 (WU) and GROUND.
^ Is the voltage greater than 3 volts?

-> Yes
REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC, test the system for normal operation.

-> No
GO to Pinpoint Test G92304t35.

G92304t35: CHECK THE LEFT-HAND REAR WSS SENSOR CIRCUIT FOR SHORT CIRCUIT TO GROUND

1. Measure the resistance between CA55, pin 02 (WU) and GROUND.
^ Is the resistance less than 10,000 ohms?

-> Yes
REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC, test the system for normal operation.

-> No
GO to Pinpoint Test G92304t36.

G92304t36: CHECK THE LEFT-HAND REAR WSS POWER CIRCUIT FOR HIGH RESISTANCE

1. Disconnect the wheel speed sensor.
2. Measure the resistance between CA55, pin 01 (G13) and JB45/JB185, pin 13 (G13).
^ Is the resistance greater than 5 ohms?

-> Yes
REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC, test the system for normal operation.

-> No
GO to Pinpoint Test G92304t37.

G92304t37: CHECK THE LEFT-HAND REAR WSS POWER CIRCUIT FOR SHORT CIRCUIT TO BATTERY

1. Measure the voltage between CA55, pin 01 (G13) and GROUND.
^ Is the voltage greater than 3 volts?

-> Yes
REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC, test the system for normal operation.

-> No
GO to Pinpoint Test G92304t38.

G92304t38: CHECK THE LEFT-HAND REAR WSS POWER CIRCUIT FOR SHORT CIRCUIT TO GROUND

1. Measure the resistance between CA55, pin 01 (G13) and GROUND.
^ Is the resistance less than 10,000 ohms?

-> Yes
REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC, test the system for normal operation.

-> No
INSTALL a new WSS. CLEAR the DTC, test the system for normal operation. If the DTC is repeated, please check part is not on any form of prior authorization before replacement.
