Interlock System
Component Location Index
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.

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.
