Found trouble code P0500 using a scan tool.

1-Check the resistance of the rear speed sensor on the rear differential. It should be 1500-2500 ohms.

2- If OK, check the wiring harness for bad connectors and for opens and shorts.

replace speed sensor as necessary.

To do so, raise the vehicle on hoist, remove brake line mounting nut and remove the brake line from the sensor stud. then, remove mounting stud from the sensor and shield. Remove sensor and shield from differential housing, and then disconnect sensor wire

harness and remove sensor.
