1. Press the brake pedal.
Go to step 2.
Repair faulty brake light circuit.
2. Turn the ignition switch ON (II), and shift to P
position.
3. Press the brake pedal, and release the accelerator
pedal.
4. Measure ILU voltage between these terminals and
body ground:
• 1999-2000 models: Between A28 terminal and
ground.
• 2001 model: Between E15 terminal and ground.
Check for an open in the wire between the
A28 terminal (1999-2000 models) or E15 terminal
(2001 model) and the multiplex control unit
(driver’s), and check for loose terminal fit in the
multiplex control unit (driver’s) connectors. If
necessary, substitute a known-good multiplex
control unit (driver’s) and recheck.
Go to step 5.
5. Turn the ignition switch OFF.
6. Disconnect these connectors from the PCM:
• 1999-2000 models: A (32P) and B (25P)
connectors.
• 2001 model: A (31P) and E (31P) connectors.
7. Press the brake pedals and measure the voltage
between these terminals.
• 1999-2000 models: Between the A32 and B20 or
B22 terminals.
• 2001 model: Between the E9 and A25 or A26
terminals.
Release the brake pedal and go to step 8.
Repair open in the wire between the A32
terminal (1999-2000 models) or E9 terminal (2001
model) and the brake pedal position switch (brake
switch).

8. Reconnect the disconnected connectors to the PCM.
9. Turn the ignition switch ON (II).
10. Measure the voltage between these terminals:
• 1999-2000 models: Between the C27 and B20 or B
22 terminals.
• 2001 model: Between the A15 and A25 or A26
terminals.
Go to step 15.
Go to step 11.
11. Turn the ignition switch OFF.
12. Disconnect the TPS connector.
13. Turn the ignition switch ON (II).
14. Measure the voltage between the No. 1 and No. 3
terminals of the TPS connector.
Check for an open or short in the wire
between the C27 terminal and the TPS. If the wire is
OK, replace the TPS.
Go to step 15.
15. Turn the ignition switch OFF, and disconnect the
PCM C (31P) connector. Check for continuity
between the No. 1 terminal of the TPS connector
and body ground, and between the No. 3 terminal
of the TPS connector and body ground.
Check for a short to ground between the
No. 1 or No. 3 terminal of the TPS connector and
ground. If the wire is OK, replace the PCM.
Go to step 16.
16. Disconnect the shift lock solenoid connector.

17. Check for continuity between the No. 2 terminal of
the shift lock solenoid connector and the No. 22
terminal of the multiplex control unit (driver’s) 22P
connector B.
Go to step 18.
Repair open in the wire between the No. 22
terminal of the multiplex control unit (driver’s) 22P
connector and the shift lock solenoid.
18. Turn the ignition switch ON (II).
19. Measure the voltage between the No. 1 terminal of
the shift lock solenoid connector and body ground.
Go to step 20.
Check for blown No. 9 (10A) fuse in the
driver’s under-dash fuse/relay box. If the fuse is OK,
repair open or short in the wire between the No. 1
terminal of the shift lock solenoid and the driver’s
under-dash fuse/relay box.
20. 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.
NOTE: Do not connect the No. 2 terminal to the
battery positive terminal or you will damage the
diode inside the shift lock solenoid.
21. Check the shift lock solenoid operation.
Check for a loose multiplex control unit
(driver’s) connector. If necessary, substitute a
known-good multiplex control unit (driver’s) and
recheck.
Replace the shift lock solenoid (see page 14-
186).
