When the shift lever is shifted to R from N, the shift lock solenoid is turned ON, and the shift lock solenoid
plunger is retracted to release the reverse lock stop. This allows the shift lever to be moved to R.

If the conditions (acceleration at 6 mph (10 km/h) or less, and deceleration at 5 mph (8 km/h) or less in D) for
turning ON the solenoid are not met, the shift lock solenoid stays OFF, and the reverse lock stop locks the shift
lever in N.

1. Clear the DTC with the HDS.

2. Start the engine.

3. With the brake pedal pressed, move the shift lever through all positions. Stop for at least 1 second in each

position, and monitor the OBD STATUS for P0705 in the DTCs/Freeze Data in A/T Mode Menu for a
pass/fail.

Does the HDS indicate FAILED?

YES - Go to step 4.

NO - Intermittent failure, the system is OK at this time. Check for an intermittent short in the wire
between the transmission range switch and the PCM. If the HDS indicates NOT COMPLETED, return to
step 2 and recheck.

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

5. Inspect the transmission range switch (see TRANSMISSION RANGE SWITCH TEST ).

Is the switch OK?

YES - Connect the switch connector, then go to step 6.

NO - Replace the transmission range switch (see TRANSMISSION RANGE SWITCH
REPLACEMENT ), then go to step 45.

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

7. Measure the voltage between PCM connector terminals D13 and A3 or B15, in all positions other than P.



Before you troubleshoot, record all freeze data and any on-board
snapshot, and review General Troubleshooting Information (see GENERAL
TROUBLESHOOTING INFORMATION ).



This code is caused by an electrical circuit problem and cannot be caused
by a mechanical problem in the transmission.
