PINPOINT TEST G92304p1 : DTC C1145, C1234; RIGHT-HAND FRONT WHEEL SPEED SENSOR (WSS) CIRCUIT FAILURE

G92304t1: CHECK THE RIGHT-HAND FRONT 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, RF01.
4. Measure the resistance between RF01, pin 02 (W) and JB45/JB185, pin 16 (WR).
^ 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 G92304t2.

G92304t2: CHECK THE RIGHT-HAND FRONT WSS SENSOR CIRCUIT FOR SHORT CIRCUIT TO BATTERY

1. Measure the voltage between RF01, pin 02 (W) 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 G92304t3.

G92304t3: CHECK THE RIGHT-HAND FRONT WSS SENSOR CIRCUIT FOR SHORT CIRCUIT TO GROUND

1. Measure the resistance between RF01, pin 02 (W) 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 G92304t5.

G92304t5: CHECK THE RIGHT-HAND FRONT WSS POWER CIRCUIT FOR HIGH RESISTANCE

1. Disconnect the wheel speed sensor.
2. Measure the resistance between RF01, pin 01 (R) and JB45/JB185 pin 15 (NR).
^ 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 G92304t6.

G92304t6: CHECK THE RIGHT-HAND FRONT WSS POWER CIRCUIT FOR SHORT CIRCUIT TO BATTERY

1. Measure the voltage between RF01, pin 01 (R) 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 G92304t7.

G92304t7: CHECK THE RIGHT-HAND FRONT WSS POWER CIRCUIT FOR SHORT CIRCUIT TO GROUND

1. Measure the resistance between RF01, pin 01 (R) 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.
