Descraption
The car is squippod with thq following dovlc6. to prevont inadvoft.nt shitting:
a A/T selector with shift locka Key cylinder with interlocked ignition key
Shift Lock Syst6m;
The shitt lock system prevents the shift lever from moving to @ or lDil from the @ position unless the brake pedalis depressed and the accelerator is in its rest oosition.
NOTE:
a The shift lever cannot be shifted when the brake pedsl and the accelerator are depressed on at the same time.a In case ot system malfunction, the shift lever can be released by pushing a key into the release slot near the shift lever.
Koy Ints.lock Systsm:
The ignition key cannot be removed from the ignition switch unless the shil-t lever is in the E positionWhen the shift lever is in any position other than @, a sol€noid is activated, making it impossible for the key to be re-moved until the shift lever is moved to the llj position.

Control Unit Input Test
Oisconnect the 8-P connector from the interlock control
unit. Check for good contact between the connector and
socket terminals. lf the terminals 8re OK, make Iollow-
ing input tests at the connector. lf all input tests are OK,
but the problem remains, replace the cont.ol unit,
NOTE: lf the shilt lock solenoid clicks when the ignition
switch is ON and the brake pedal is pushed (shift tever
is in lfl position, accelerator is in rest position), the shiftlock system is electronically normal; test the A/T gear
positaon switch as described on page 23- 134.
