A/T SHIFT LOCK SYSTEM

A/T SHIFT LOCK SYSTEMPFP:34950
DescriptionBCS0014Z

The electrical key interlock mechanism also operates as a shift lock:
With the ignition switch turned to ON, selector lever cannot be shifted from “P” to any other position unless
brake pedal is depressed.
With the key removed, selector lever cannot be shifted from “P” to any other position.
The key cannot be removed unless selector lever is placed in “P”.

The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside key cylinder, respectively.
Shift Lock System Electrical Parts LocationBCS00150
NOTE:
This emergency lever insures that when battery is off ignition key cannot be removed.Inthe situation like this,
by operating this lever, ignition key can be removed.

Data are reference values.
NOTE:
Make sure that the pointer swings only momentarily because the output time is so short. If the inspection is done with an oscilloscope, it
should be observed that the power source voltage lasts for 3.5 to 10 ms.

Component InspectionBCS00153
SHIFT LOCK SOLENOID
Check operation by applying battery voltage to A/T device harness
connector terminal.
CAUTION:
Be sure to apply the voltage of the correct polarity to the
respective terminals. Otherwise, the part may be damaged.
DETENTION SWITCH (FOR KEY)
Check continuity between terminals of A/T device harness connector
terminals.
DETENTION SWITCH (FOR SHIFT)
Check continuity between terminals of A/T device harness connector
terminals.
KEY LOCK SOLENOID
Key Lock (With Intelligent Key)
Check operation by applying battery voltage to ignition knob switch,
key switch and key lock solenoid harness connector terminal.
CAUTION:
Be careful not to cause burnout of harness.
