45. Reconnect all connectors.

46. Turn the ignition switch to ON (II).

47. Clear the DTC with the HDS.

48. Start the engine.

49. With the brake pedal pressed, move the shift lever

through all positions. Stop for at least 1 second in
each position.

50. Check for Temporary DTCs or DTCs with the HDS.

Check for intermittent short to body ground

in the wires between the transmission range switch
and the PCM, then go to step 1.

Go to step 51.

51. Monitor the OBD STATUS for P0705 in the DTCs

MENU with the HDS.

Troubleshooting is complete. If any other

Temporary DTCs or DTCs were indicated in step 50,
go to the indicated DTC’s troubleshooting.

If the HDS indicates FAILED, check for

intermittent short to body ground in the wires
between the transmission range switch and the
PCM, then go to step 1. If the HDS indicates NOT
COMPLETED, go to step 48.

52. Reconnect all connectors.

53. Update the PCM if it does not have the latest

software (see page 11-227), or substitute a known-
good PCM (see page 11-7).

54. Start the engine.

55. With the brake pedal pressed, move the shift lever

through all positions. Stop for at least 1 second in
each position.

56. Check for Temporary DTCs or DTCs with the HDS.

Check for intermittent short to body ground

in the wires between the transmission range switch
and the PCM. If the PCM was updated, substitute a
known-good PCM (see page 11-7), then go to step
54. If the PCM was substituted, go to step 1.

Go to step 57.

57. Monitor the OBD STATUS for P0705 in the DTCs

MENU with the HDS.

If the PCM was updated, troubleshooting is

complete. If the PCM was substituted, replace the
original PCM (see page 11-228). If any other
Temporary DTCs or DTCs were indicated in step 56,
go to the indicated DTC’s troubleshooting.

If the HDS indicates FAILED, check for

intermittent short to body ground in the wires
between the transmission range switch and the
PCM. If the PCM was updated, substitute a known-
good PCM (see page 11-7), then go to step 54. If the
PCM was substituted, go to step 1. If the HDS
indicates NOT COMPLETED, go to step 54.

vehicle, make sure it is securely supported, and
allow the front wheels to rotate freely, or raise the
vehicle on a lift.

4. Start the engine, disable the VSA by pressing the

VSA OFF switch (if equipped), run the vehicle with
the shift lever in D until the vehicle speed reaches
40 km/h (25 mph), then slow down and stop the
wheels.

5. Monitor the OBD STATUS for P0706 in the DTCs

MENU with the HDS.

Go to step 6.

If the HDS indicates PASSED, intermittent

failure, the system is OK at this time. Check for
poor connections or loose terminals between the
transmission range switch and the PCM. If the HDS
indicates NOT COMPLETED, go to step 4.

6. Turn the ignition switch to LOCK (0).

7. Inspect the transmission range switch (see page

14-265).

Go to step 8.

Replace the transmission range switch

(see page 14-267), then go to step 25.

8. Adjust the shift cable (see page 14-259).

9. Turn the ignition switch to ON (II).

10. Clear the DTC with the HDS.

11. Start the engine, disable the VSA by pressing the

VSA OFF switch (if equipped), run the vehicle with
the shift lever in D until the vehicle speed reaches
40 km/h (25 mph), then slow down and stop the
wheels.

12. Monitor the OBD STATUS for P0706 in the DTCs

MENU with the HDS.

Go to step 13.

If the HDS indicates PASSED, troubleshooting

is complete. If the HDS indicates NOT COMPLETED,
go to step 11.

13. Shift to D, and check the Forward Switch (ATPFWD)

and A/T D Switch in the DATA LIST with the HDS.

Go to step 14.

Go to step 18.

14. Shift to S, and check the Forward Switch (ATPFWD)

and A/T S Switch in the DATA LIST with the HDS.

Go to step 15.
