Key Interlock System Circuit Troubleshooting

KEY SWITCH CONNECTOR (7P)

WHT/YEL

PARK PIN SWITCH CONNECTOR

1. Disconnect the key switch connector (7P) from the

steering lock assembly.

2. Connect the No. 7 terminal of the key switch

connector to the battery positive terminal, and
connect the No. 5 terminal to the battery negative
terminal.

3. Turn the ignition switch to ACC (I), then push the

ignition key.

4. Check the key interlock solenoid operation. A

clicking sound should be heard while pushing the
ignition key, and you should not be able to turn it to
the OFF position.

Go to step 5.

Faulty key interlock solenoid/switch. Replace

the ignition key cylinder/steering lock assembly.

5. Measure the voltage between the No. 7 terminal

and body ground.

Go to step 6.

Check for a blown No. 47 (20A) fuse in the

under-hood fuse/relay box. If the fuse is OK, repair
open or short in the wire between the No. 7
terminal of the key switch connector and under-
hood fuse/relay box.

6. Disconnect the park pin switch connector on the

shift lever.

7. With the shift lever in Park and pulled back toward

the driver, check for continuity between the No. 1
and No. 3 terminals of the park pin switch
connector.

Go to step 8.

Repair open in the wires between the park pin

switch and the connector. If the wires are OK,
replace the park pin switch .

8. Check for continuity between the No. 3 terminal of

the park pin switch connector and the No. 5
terminal of the key switch connector.

Go to step 9.

Repair open in the wire between No. 3

terminal of the park pin switch connector and the
No. 5 terminal of the key switch connector.

9. Check for continuity between the No. 1 terminal of

the park pin switch connector and body ground.

Check for a loose key switch connector and

park pin switch connector. If necessary, substitute a
known-good steering lock assembly.

Repair open in the wire between the No. 1

terminal of the park pin switch connector and
ground (G401), or repair poor ground (G401).

A/T Interlock System

Control Unit Input Test

SRS components are located in this area. Review the SRS component locations (see page 23-18), and the precautions
and 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 A/T gear position 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 (see page 23-18), 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 No. 5 and No. 7

terminals 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 No. 7 terminal and ground
connected to the No. 3 terminals.

• 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 (see page 23-18), 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 No. 1 terminal of the shift lock solenoid

connector to the battery positive terminal, and
connect the No. 2 terminal to the battery negative
terminal.

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 No. 2 terminal
(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.
