SHIFT LOCK SYSTEM
Component Function CheckINFOID:0000000006226882
1.CHECK A/T SHIFT LOCK OPERATION (PART 1)
1. Turn ignition switch ON.
2. Shift the selector lever to “P” position.
3. Attempt to shift the selector lever to any other position with the brake pedal released.
Can the selector lever be shifted to any other position?
YES >> Go to TM-157, "Diagnosis Procedure".
NO >> GO TO 2.
2.CHECK A/T SHIFT LOCK OPERATION (PART 2)
Attempt to shift the selector lever to any other position with the brake pedal depressed.
Can the selector lever be shifted to any other position?
YES >> INSPECTION END
NO >> Go to TM-157, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000006226883
1. CHECK POWER SOURCE
1. Turn ignition switch OFF.
2. Disconnect fuse block (J/B) connector.
3. Turn ignition switch ON.
4. Check voltage between fuse block (J/B) connector terminal and ground.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Check the following.  10A fuse [No. 3, located in fuse block (J/B)]. Refer to PG-140, "
Fuse, Connector and Terminal
Arrangement".
 Harness for short or open between ignition switch and fuse block (J/B). Refer to PG-89, "
Wiring
Diagram - IGNITION POWER SUPPLY -".
 Ignition switch
2.CHECK HARNESS BETWEEN FUSE BLOCK (J/B ) AND STOP LAMP SWITCH (PART 1)
1. Turn ignition switch OFF.
2. Disconnect stop lamp switch connector.
3. Check continuity between fuse block (J/B) vehicl e side harness connector terminal and stop lamp switch
vehicle side harness connector terminal.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace damaged parts.
3.CHECK HARNESS BETWEEN FUSE BLOCK (J/B ) AND STOP LAMP SWITCH (PART 2)
Check continuity between stop lamp switch vehicle side harness connector terminal and ground.
