PINPOINT TEST G531322p4: LEFT HAND FRONT WHEEL SPEED SENSOR (WSS)

G531322t15: CHECK THE WSS RETURN CIRCUIT FOR SHORT CIRCUIT TO GROUND
1.

3. Key off.
4. Disconnect the WSS connector, EC044.
5. Disconnect the ABS module connector, ECO30.
6. Key on, engine off.
7. Measure the resistance between:

^ Is the resistance greater than 100 Kohms?

-> Yes GO to Pinpoint Test G531322t16.

-> No REPAIR the short circuit. For additional information, refer to Vehicle/Diagrams. Clear the DTC, test the system for normal operation by driving the vehicle at more than 20 kph (12.5 mph) for more than 3 minutes.

G531322t16: CHECK THE WSS RETURN CIRCUIT FOR SHORT CIRCUIT TO POWER
1. Measure the resistance between:

^ Is the resistance greater than 100 Kohms?

-> Yes GO to Pinpoint Test G531322t17.

-> No REPAIR the short circuit. For additional information, refer to Vehicle/Diagrams. Clear the DTC, test the system for normal operation by driving the vehicle at more than 20 kph (12.5 mph) for more than 3 minutes.

G531322t17: CHECK THE WSS RETURN CIRCUIT FOR HIGH RESISTANCE
1. Measure the resistance between:

^ Is the resistance less than 10 ohms?

-> Yes GO to Pinpoint Test G531322t18.

-> No REPAIR the high resistance circuit. For additional information, refer to Vehicle/Diagrams. Clear the DTC, test the system for normal operation by driving the vehicle at more than 20 kph (12.5 mph) for more than 3 minutes.

G531322t18: CHECK THE WSS SIGNAL CIRCUIT FOR SHORT CIRCUIT TO POWER
1. Measure the resistance between:

^ Is the resistance greater than 100 Kohms?

-> Yes GO to Pinpoint Test G531322t19.

-> No REPAIR the short circuit. For additional information, refer to Vehicle/Diagrams. Clear the DTC, test the system for normal operation by driving the vehicle at more than 20 kph (12.5 mph) for more than 3 minutes.

G531322t19: CHECK THE WSS SIGNAL CIRCUIT FOR SHORT CIRCUIT TO GROUND
1. Measure the resistance between:

^ Is the resistance greater than 100 Kohms?

-> Yes GO to Pinpoint Test G531322t20.

-> No REPAIR the short circuit. For additional information, refer to Vehicle/Diagrams. Clear the DTC, test the system for normal operation by driving the vehicle at more than 20 kph (12.5 mph) for more than 3 minutes.

G531322t20: CHECK THE WSS SIGNAL CIRCUIT FOR HIGH RESISTANCE
1. Measure the resistance between:

^ Is the resistance less than 10 ohms?

-> Yes GO to Pinpoint Test G531322t21.

-> No REPAIR the high resistance circuit. For additional information, refer to Vehicle/Diagrams. Clear the DTC, test the system for normal operation by driving the vehicle at more than 20 kph (12.5 mph) for more than 3 minutes.

G531322t21: CHECK THE WSS SIGNAL AND RETURN CIRCUITS FOR SHORT CIRCUIT TO EACH OTHER
1. Measure the resistance between:

^ Is the resistance greater than 100 Kohms?

-> Yes An intermittent fault may be present in the wiring harness. Visually check for chaffed wires or other physical damage to the harness. If no fault is found in the harness, suspect the following components: - WSS connector - WSS - ABS module connector - ABS module

-> No REPAIR the short circuit. For additional information, refer to Vehicle/Diagrams. Clear the DTC, test the system for normal operation by driving the vehicle at more than 20 kph (12.5 mph) for more than 3 minutes.
