When the vehicle speed increases, the PCM sends a signal to A/T clutch pressure control solenoid valve A to increase
A/T clutch pressure control solenoid valve A pressure (55), and the lock-up control valve is moved to the left by the
increased pressure. Then torque converter pressure (94) from the left side of the torque converter is completely
released at the lock-up control valve, and torque converter pressure (91) engages the torque converter clutch securely;
the torque converter clutch is in full lock-up.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

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.

SHIFT LOCK RELEASE
When the shift lock system does not operate due to a mechanical or electrical trouble, you can unlock the shift lock
temporarily by inserting the ignition key into the shift lock release hole and pressing the shift lock release. When the
shift lock release is pressed, the shift lock stop releases the lock pin, and the shift lever can move to any other position.

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).
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch to LOCK (0), then turn it to ON (II) again.
4. Check for Temporary DTCs or DTCs in the PGM-FI SYSTEM with the HDS.
Go to the indicated DTC’s troubleshooting in
the PGM-FI system.
 P0107 (see page 11-80)
 P0108 (see page 11-82) Go to step 5.
5. Check for Temporary DTCs or DTCs in the A/T SYSTEM with the HDS.
Go to step 6.
Intermittent failure, the system is OK at this
time. If any other Temporary DTCs or DTCs were
indicated, go to the indicated DTC’s
troubleshooting.
6. 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).
7. Start the engine, and wait for at least 2 minutes. 8. Check for Temporary DTCs or DTCs in the A/T
SYSTEM with the HDS.
Check for poor connections or loose
terminals at the PCM. If the PCM was updated,
substitute a known-good PCM (see page 11-7), then
go to step 7. If the PCM was substituted, go to step
1.
Go to step 9.
9. Monitor the OBD STATUS for P0107 or P0108 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 8,
go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, check for poor
connections or loose terminals at the PCM. If the
PCM was updated, substitute a known-good PCM
(see page 11-7), then go to step 7. If the PCM was
substituted, go to step 1. If the HDS indicates NOT
COMPLETED, go to step 7.

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.
