Transmission range switch test has finished if the test results are OK. If there is no continuity between any terminals, go to step 5.
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.

If the transmission range switch continuity check is OK, replace the faulty transmission range switch harness.
If there is no continuity between any terminals, remove the transmission range switch, and check the end of the selector control shaft (A).
Selector Control Shaft:

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.)
