1. Remove the console. then disconnect the 14P con-
nector from the switch.
2. Remove the two console switch mounting nuts.
3.
1.
Position the switch slider to "Neutral" as shown
above.
Move the shitt lever to "Neutral", then slip the
switch into position.
Attach the switch with the two nuts.
Test the switch in the @ and I position of the shift
lever. The engine should start when the shift lever
is in position E anywhere in the range of free play.
Connect the l4P connector, clamp the harness and
install the console.

1. Shitt to the @ position, and loosen the nuts.
2. Slide the switch in the direction of @ position
lwithin 2.0 mm (O.079 in.)l so that there is continuity
between the "A" and "L" terminals in the range oI
free play oI the shift lever.
3. Recheck for continuity between each of the ter-
manals.
NOTE:
a ll adjustment is not possible, check for damage
to the shift lever detent and/or the bracket. lf
there is no damage, replace the console switch.

Description
The car is equipped with the lollowing devices to plevent inadvertent shifiing:
a A/T selector with shift lock
a Key cylinder with interlocked ignition key
Shift Lock Svstem:
The shift lock system prevents the shilt lever trom moving to @ or [6ol from the p position unless the brake pedal
is depressed and the accelerator is in its rest position.
NOTE:
a The shift lever cannot be shifted when the brake pedal and the accelerator are depressed at the same time.
a In case of system malfunction, the shift lever can be released by pushing a key into the release slot near the shift lever.
SRS components are located in this area. Review the SRS component locations, precautions, and procedures in the SRS
section (23) belore performing repairs or service.

Description
Ths cal is equipped with the tottowing devices to prevent inadvertenl shifting:
a Key cylinder with interlocked ignition key (Key Interlock System)
a shift lever with shift lock (shilt Lock system)
Key Interlock System:
When the shift lever is in any other position than @ or is not securely locked in @ (parking pin switch is ON), a solenoid
is activated, making it impossible to remove the ignition key from the ignition switch.
To be able to remove the key, the shift lever must be in E] and must be securely locked in this position {parking pin
switch must be turned oft by the lock pin)
The shift lever is in any othel position than El and the psrking pin switch is ON:

Control Unit Input Test
1. Disconnect the 8P connector from the interlock con-
trol unit.
2. lnspect the connector and socket terminals to be
sure they are all making good contact.
a It the terminals are bent, loose or corroded, repair
them as necessary, and recheck the system.
a lf the terminals look OK, make the following in-
put tests at the connector.- lf a test indicates a problem, tind and correct
the cause, then recheck the system.- lf all the input tests prove OK, substitute a
known-good control unit, and recheck the sys-
tem. lf the check is OK, the control unit must
be faulty; replace it.
NOTE: lf the shift lock solenoid clicks when the igni-
tion switch is turned ON (ll) and you step on the
brske Dedal (with the shift lever in E). the shift lock
system is electronically normal; if the shift lever
cannot be shifted from fl, test the 46 gear position
switch as described on page 23-142, and see sec-
tion 14.

1.Remove the console, then disconnect the 2P con-
nector of the shift lock solenoid trom the main wire
harness.
NOTE: Do not connect power to the B (- ) terminal
(reverse polarity) or you will damage the diode in-
side the solenoid.
Connect battery power to the A terminal, ground the
B terminal momentarily, and check solenoid
operation.
a lf the solenoid does not operate, replace it as
described in steps 3,4, and 5.
a lf the solenoid does operate, check and, i{ neces
sary, adjust its two positions as shown in step 5.
