1. Remove the intake air duct (see page 11-348) and
the air cleaner assembly (see page 11-345).
2. Disconnect the transmission range switch subharness connector (A).
3. 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. 4. Transmission range switch test has completed if
the test results are OK, go to step 12. If there is no
continuity between any terminals, go to step 5.
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.
6. Remove the transmission range switch cover.

7. Disconnect the transmission range switch
connector.
8. Check for continuity between the terminals at the switch connector. There should be continuity
between the terminals in the following table for
each switch position.
9. If the transmission range switch test is OK, replace the faulty transmission range switch harness, then
go to step 12. If there is no continuity between any
terminals, go to step 10. 10. Remove the transmission range switch, and check
the end of the selector control shaft (A).
11. If the measurement at the end of the selector control shaft is within the standard, replace the
transmission range switch. If the measurement is
out of the standard, repair the selector control shaft
end, and recheck the transmission range switch
continuity.
12. Check the connector for rust, dirt, or oil, clean or repair if necessary, then connect the connector
securely.
13. Install the removed parts in the reverse order of removal.

1. 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.
2. Move the shift lever to N.
3. Remove the transmission range switch cover.
4. Remove the transmission range switch. 5. Make sure the control shaft is in the N position. If
necessary, move the shift lever to N from P.
NOTE: Do not use the selector control shaft to
adjust the shift position. If the control shaft tips are
squeezed together it will cause a faulty signal or
position due to play between the selector control
shaft and the transmission range switch.
6. Align the cutouts (A) on the rotary-frame with the neutral positioning cutouts (B) on the transmission
range switch (C), then put a 2.0 mm (0.08 in.) feeler
gauge blade (D) in the cutouts to hold the switch in
the N position.
NOTE: Be sure to use a 2.0 mm (0.08 in.) blade or
equivalent to hold the switch in the N position.

7. Install the transmission range switch (A) gently on
the selector control shaft (B) while holding it in the
N position with the 2.0 mm (0.08 in.) blade (C).
8. Tighten the bolts on the transmission range switch while you continue to holding the N position. Do
not move the transmission range switch when
tightening the bolts. Remove the feeler gauge. 9. Check the connectors for rust, dirt, or oil, clean or
repair if necessary, then connect the connector
securely.
10. Turn the ignition switch to ON (II). Move the shift lever through all positions, and check the
transmission range switch synchronization with the
A/T gear position indicator.
11. Check that the engine will start with the shift lever in P and N, and will not start in any other shift lever
position.
12. Check that the back-up lights come on when the shift lever is in R.
13. Allow the front wheels to rotate freely, then start the engine, and check the shift lever operation.
14. Install the transmission range switch cover (A).
