1. Connect the HDS to the DLC.
2. Select Shift Lock Solenoid Test in the
Miscellaneous Test Menu, and check that the shift
lock solenoid operates with the HDS.
Go to step 16.
Go to step 3.
3. Turn the ignition switch to LOCK (0).
4. Remove the driver’s dashboard lower cover
(see page 20-83).
5. Remove the steering column covers (see page
17-24), and lower the steering column.
6. Disconnect the D3 switch/shift lock solenoid/park
pin switch connector.
7. Turn the ignition switch to ON (II).
8. Measure the voltage between D3 switch/shift lock
solenoid/park pin switch connector terminal No. 5
and body ground.
Go to step 9.
Check for a blown No. 32 (7.5 A)
No. 21

fuse in the under-dash fuse/relay box. If
the fuse is OK, repair an open or a short in the wire
between the D3 switch/shift lock solenoid/park pin
switch connector and the under-dash fuse/relay
box.

9. Shift the shift lever into P, and press the brake
pedal. Do not press the accelerator.
10. Measure the voltage between D3 switch/shift lock
solenoid/park pin switch connector terminals No. 5
and No. 6 while pressing the brake pedal.
Go to step 11.
Go to step 12.

11. Release the brake pedal, and measure the voltage
between D3 switch/shift lock solenoid/park pin
switch connector terminals No. 5 and No. 6. The
shift lever must be in P.
Repair a short to ground in the wire between
PCM connector terminal A2 and the D3 switch/shift
lock solenoid/park pin switch connector.
Check the shift lock mechanism. If the
mechanism is OK, replace the shift lock solenoid
(see page 14-287).

12. Turn the ignition switch to LOCK (0).
13. Jump the SCS line with the HDS.
14. Disconnect PCM connector A (44P).
15. Check for continuity between PCM connector
terminal A2 and D3 switch/shift lock solenoid/park
pin switch connector terminal No. 6.
Substitute a known-good PCM (see page
14-9) and recheck.
Repair an open in the wire between PCM
connector terminal A2 and the D3 switch/shift lock
solenoid/park pin switch connector.

16. Press the brake pedal.
Go to step 17.
Repair faulty brake light circuit.
17. Turn the ignition switch to LOCK (0).
18. Jump the SCS line with the HDS.
19. Disconnect PCM connector A (44P).
20. Measure the voltage between PCM connector
terminal A8 and body ground while pressing the
brake pedal and when the brake pedal is released.
Go to step 22.
Go to step 21.
21. Check for continuity between PCM connector
terminal A8 and body ground.
Repair a short to ground in the wire between
PCM connector terminal A8 and the brake pedal
position switch.
Repair an open in the wire between PCM
connector terminal A8 and the brake pedal position
switch.
22. Connect PCM connector A (44P).
23. Connect the HDS to the DLC.
24. Start the engine.
25. Check the engine speed and the accelerator pedal
position in the DATA LIST with the HDS.
Go to step 26.
Substitute a known-good PCM (see page 14-9)
and recheck.
26. Check the throttle cable adjustment (see page
11-317).
Check the throttle body (see page 11-314).
Adjust the throttle cable (see page 11-317).
