The shift lock system prevents the shift lever from mis-shifting. The shift lock solenoid is usually OFF. After starting
the engine in P, the shift lever ca
nnot move to any other position from P because the shift lock stop stops the lock pin
unless the brake pedal is pressed. When the brake pedal is pressed and the accelerator pedal is not pressed, the shift
lock solenoid is ON; the shift lock solenoid plunger in the shift lock solenoid pulls the shift lock stop to release the lock
pin. Pressing the shift lever button, allows the shift lever to move to any other position. When the brake pedal and the
accelerator pedal are pressed at the same time, the shift lock system is not unlocked.

NOTE:
 Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review
General Troubleshooting Information (see page 14-3).
 This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the
transmission.
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Start the engine.
4. With the brake pedal pressed, move the shift lever through all positions. Stop for at least 1 second in
each position.
5. Monitor the OBD STATUS for P0705 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
intermittent short to body ground in the wires
between the transmission range switch and the
PCM. If the HDS indicates NOT COMPLETED, go to
step 3.
6. Turn the ignition switch to LOCK (0).
7. Inspect the transmission range switch (see page 14-265).
With the switch connector disconnected, go
to step 8.
Replace the transmission range switch
(see page 14-267), then go to step 45. 8. Turn the ignition switch to ON (II).
9. Measure the voltage between transmission range
switch connector terminals No. 6 and No. 10.
Go to step 15.
Go to step 10.

1. Apply the parking brake, and block both rear
wheels.
2. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
3. Shift to D while pressing the brake pedal. Press the accelerator pedal, and release it suddenly. The
engine should not stall.
4. Repeat step 3 in all shift lever positions.
5. Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.
6. Turn the ignition switch to ON (II), and go to the A/T Data List. Make sure the HDS communicates with
the PCM. If it does not, go to the DLC circuit
troubleshooting (see page 11- 204).7. Prepare the HDS to take a HIGH SPEED SNAPSHOT
(refer to the HDS user guide for more details if
needed):
 Select High Speed icon.
 Select these parameters: – Vehicle Speed
– Output Shaft (Countershaft) Speed (rpm)
– Input Shaft (Mainshaft) Speed (rpm)
– Engine Speed
– APP Sensor A (V)
– ATF Temp Sensor (V)
– Battery Voltage
– Shift Control
– Brake Switch
 Set the Trigger Type to Parameter.
 Adjust the Parameter setting to APP Sensor A above 1.2 V.
 Set the recording time to 60 seconds.
 Set the Trigger point to 30 seconds.
8. Find a suitable level road. When you are ready to do the test, press OK on the HDS.
9. Monitor the HDS and accelerate quickly until the APP Sensor A reads 1.3 V. Maintain a steady
throttle until the transmission shifts to 5th gear,
then slow the vehicle and come to a stop.
10. Save the snapshot if the entire event was recorded or increase the recording time setting as necessary
and repeat step 9.
11. Adjust the Parameter setting to 2.4 V. Retest-drive the vehicle. While monitoring the HDS, accelerate
quickly until the APP Sensor A reads 2.5 V.
Maintain a steady throttle until the transmission
shifts to 5th gear (or reasonable speed), then slow
the vehicle and come to a stop.
12. Save the snapshot if the entire event was recorded or increase the recording time setting as necessary
and repeat step 11.
13. Accelerate quickly until the accelerator pedal is to the floor. Maintain a steady pedal until the
transmission shifts to 3rd gear, then slow to a stop,
and save the snapshot.
