12. Disconnect PCM connector B (44P).
13. Connect cable reel 20P connector terminal No. 17and body ground with a jumper wire. 14. Check for continuity between PCM connector
terminal B40 and body ground.
Check for poor connections or loose
terminals between cable reel 20P connector
terminal No. 17 and PCM connector terminal B40. If
the connection is OK, update the PCM if it does not
have the latest software (see page 11-227), or
subsitute a known-good PCM (see page 11-7), then
recheck. If the symptom goes away with a known-
good PCM, replace the original PCM (see page
11-228).
Repair open in the wire between PCM
connector terminal B40 and the cable reel 20P
connector.

1. Connect the HDS to the DLC located under the
driver’s side of the dashboard.
2. Turn the ignition switch to ON (II). Make sure the HDS communicates with the PCM. If it does not, go
to the DLC circuit troubleshooting (see page
11-204).
3. 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 5.
4. Turn the ignition switch to LOCK (0).
5. Remove the center console (see page 20-92).
6. Disconnect the shift lock solenoid connector.
7. Turn the ignition switch to ON (II). 8. Measure the voltage between shift lock solenoid
connector terminal No. 1 and body ground.
Go to step 9.
CheckforablownNo.10(7.5A)fuseinthe
under-dash fuse/relay box. If the fuse is OK, repair
open in the wire between the shift lock solenoid
connector and the under-dash fuse/relay box.
9. Shift the shift lever to P, and press the brake pedal. Do not press the accelerator.
10. Measure the voltage between shift lock solenoid connector terminals No. 1 and No. 2 while pressing
the brake pedal.
Go to step 11.
Go to step 12.

11. Release the brake pedal, and measure the voltage between shift lock solenoid connector terminals
No. 1 and No. 2. The shift lever must be in P.
Repair short to body ground in the wire
between PCM connector terminal A27 and the shift
lock solenoid.
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 A27 and shift lock solenoid connector
terminal No. 2.
Check for poor connections or loose
terminals between shift lock solenoid connector
terminal No. 2 and PCM connector terminal A27. If
the connection is OK, 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), then
recheck. If the symptom goes away with a known-
good PCM, replace the original PCM (see page
11-228).
Repair open in the wire between PCM

16. Monitor the Brake Switch in the Data List with the
HDS, and press the brake pedal.
Go to step 21.
If the brake lights come on, go to step 17. If
the brake lights do not work, repair the 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 A40 and body ground when pressing the
brake pedal and when the brake pedal is released.
Reconnect all connectors, then 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), then recheck. If the symptom goes
away with a known-good PCM, replace the original
PCM (see page 11-228).
Repair open in the wire between PCM
connector terminal A40 and the brake pedal
position switch.
21. Monitor the A/T P Switch in the Data List with the HDS with the shift lever in P.
Go to step 33.
Go to step 22.
