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.

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).

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

1. Connect the HDS to the DLC (A) 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

3. Select Shift Lock Solenoid Test in the Miscellaneous Test Menu, and check that the shift
lock solenoid operates with the HDS.
4. Check that the shift lever can be moved out of P when Shift Lock Solenoid is ON. Move the shift
lever back in P, and check it locks when Shift Lock
Solenoid is OFF.
5. Check that the shift lock releases when the shift lock release is pushed, and check that it locks when
the shift lock release is released.
6. If the shift lock solenoid does not work properly, go to the shift lock system troubleshooting (see page
14-280). NOTE: Make sure not to get any silicone grease on the
terminal part of the connectors and switches, especially
if you have silicone grease on your hands or gloves.
1. Remove the shift lever assembly (see page 14-254).
2. Remove the shift lock solenoid connector.
3. Release the shift lock solenoid lock (A), then remove the shift lock solenoid (B).

7. Install the column covers (see page 17-9).
8. Install the driver’s dashboard undercover (see page 20-103). 9. Do the battery terminal reconnection procedure
(see page 22-68), and do these tasks:
 Turn the ignition switch to ON (II), and check that the SRS indicator comes on for about 6 seconds
and then goes off.
 Make sure the horn and turn signal switches work properly.
 Make sure the steering wheel switches work properly.
10. After installation, do these checks:  Check the steering wheel spoke angle. If thesteering spoke angles to the right and left are not
equal (steering wheel and rack are not centered),
correct the engagement of the joint/pinion shaft
splines.
 Set the steering column to the center tilt position, and to the center telescopic position, then do the
front toe inspection (see page 18-5).
