1. SHIFT LOCK OPERATION
Step Check Yes No
1CHECK SHIFT LOCK.
1) Turn the ignition switch to ON.
2) Shift the select lever to “P” range.
While brake pedal is not
depressed, is it possible to
move the select lever from the
“P” range to other ranges?
Inspect “SELECT
LEVER CANNOT
BE SHIFT
LOCKED”. to CS-12, SELECT
LEVER CANNOT
BE SHIFTED,
INSPECTION, AT
Shift Lock Control
System.>
Go to step 2.
2CHECK SHIFT LOCK.While brake pedal is
depressed, is it possible to
move the select lever from the
“P” range to other ranges?
Go to step 3.Inspect “SELECT
LEVER SHIFT
LOCK CANNOT
BE RELEASED”.
SHIFT LOCK OF
SELECT LEVER
CANNOT BE
RELEASED.,

3CHECK KEY INTERLOCK.Can the ignition switch be
turned to the “LOCK” position
when the select lever is set to
other than “P” range?
Go to step 4.Go to step 5.
4CHECK BACKUP POWER SUPPLY.
Inspect the backup power supply circuit. to CS-10, BODY INTEGRATED UNIT POWER
SUPPLY AND GROUND CIRCUIT, INSPEC-
TION, AT Shift Lock Control System.>
Is the backup power supply cir-
cuit operating properly?
Inspect for “KEY
