Raise the vehicle on a lift, or apply the parking brake, block the rear wheels, and raise the front of the vehicle. Make sure it is securely supported.

Disconnect the transmission range switch harness connector (A), then remove the connector from the clamp bracket (B).

Remove the transmission range switch harness clamps (C) from the clamp bracket (D).

Check for continuity between the terminals at the harness connector. There should be continuity between the terminals in the following table for each switch position.

Transmission range switch test is completed if the test results are OK.

If there is no continuity between any terminals, go to Step 6 .

Remove the transmission range switch cover.

Disconnect the transmission range switch connector.

Check for continuity between the terminals at the transmission range switch connector. There should be continuity between the terminals in the following table for each transmission range switch position.

If the transmission range switch continuity check is OK, replace the faulty transmission range switch harness.

If there is no continuity between any terminals, go to Step 10 .

Remove the transmission range switch, and check the end of the selector control shaft (A).

Selector Control Shaft Specifications:
Width (B):	6.1−6.2 mm (0.240−0.244 in.)
End Gap (C):	1.8−2.0 mm (0.07−0.08 in.)

If the measurement of the selector control shaft end is within the specification, replace the transmission range switch. If the measurement is out of the specification, repair the selector control shaft end, and recheck the transmission range switch continuity.
