A/T Interlock System
Control Unit Input Test
SRS components are located in this area. Review the SRS component locations, 2002 model (see page 23-19), 2003-
2004 models (see page 23-20), and the precautions and the procedures (see page 23-21) in the SRS before performing
repairs or service.
1. Disconnect the 22P connector from the multiplex control unit, driver’s, then remove the control unit from the
driver’s under-dash fuse/relay box.
2. Inspect the connectors and connector terminals to be sure they are all making good contact.
• If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
• If the terminals look OK, go to step 3.
NOTE: If the shift lock solenoid clicks when the ignition switch is turned ON (II) while pressing the brake pedal with
the shift lever in the P position, the shift lock system is OK. If the shift lever cannot be shifted from the P position,
test the transmission range switch.
3. With the control unit still disconnected from its connectors and the fuse/relay box, make these input tests.
• If a test indicates a problem, find and correct the cause, then recheck the system.
• If all the input tests prove OK, go to step 4.

4. Reconnect the connectors to the multiplex control unit, and make this input test.
• If a test indicates a problem, find and correct the cause, then recheck the system.
• If all the input tests prove OK, substitute a known-good multiplex control unit, and recheck the system.
If the system is OK, the multiplex control unit must be faulty; replace it.

Key Interlock Solenoid/Switch Test
Shift Lock Solenoid Test
KEY SWITCH CONNECTOR (7P)
SRS components are located in this area. Review the
SRS component locations, 2002 model (see page 23-19),
2003-2004 models (see page 23-20), and the
precautions and procedures (see page 23-21) in the SRS
before performing repairs or service.
1. Remove the steering lower cover (see page 17-25).
2. Disconnect the key switch connector (7P) from the
steering lock assembly.
3. Check for continuity between the terminals No. 5
and No. 7 when the key is pushed, and check for no
continuity when the key is released.
4. Check that the key cannot be removed with power
connected to the terminal No. 7 and ground
connected to the terminal No. 3.
• If the key cannot be removed, the key interlock
solenoid is OK.
• If the key can be removed, replace the steering
lock assembly (the key interlock solenoid is not
available separately).
SRS components are located in this area. Review the
SRS component locations, 2002 model (see page 23-19),
2003-2004 models (see page 23-20), and the
precautions and procedures (see page 23-21) in the SRS
before performing repairs or service.
1. Remove the steering column upper cover (see page
17-25).
2. Disconnect the shift lock solenoid 2P connector.
3. Connect the battery positive terminal shift lock
solenoid connector terminal No. 1, and connect the
battery negative terminal to the terminal No. 2.
4. Check that the shift lever can be moved from the P
position. Release the battery terminals from the
shift lock solenoid connector. Move the shift lever
back to the P position, and make sure it locks.
NOTE: Do not connect power to the terminal No. 2
(reverse polarity) or you will damage the diode
inside the solenoid.
5. Check that the shift lock releases when the release
lever is pushed, and check that it locks when the
release lever is released.
6. If the solenoid does not work, replace it.

3. Remove the nut (A) securing the shift cable end (B),
then separate the shift cable (C) from the shift lever
assembly (D).
4. Disconnect the shift lock solenoid connector (A)
and the park pin switch connector (B).
5. Remove the three bolts (C) securing the shift lever
assembly, then remove the shift lever assembly (D).
6. Remove the screws (A) securing the shift lock
solenoid (B), then remove the shift lock solenoid.
7. Install the shift lock solenoid plunger (C) and
plunger spring (D) in the new shift lock solenoid.
8. Install the shift lock solenoid by aligning the joint of
the shift lock solenoid with the tip of the shift lock
extension (E), then tighten the screws.
9. Install the shift lever assembly.
10. Install the shift cable end to the shift lever. If
necessary, adjust the shift cable (see step 5 on
page 14-395).
