Data are reference values.

NOTE: Confirm 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.

DIAGNOSTIC PROCEDURE
COLUMN SHIFT

SYMPTOM 1:
^ Selector lever cannot be moved from P position with key in ON position and brake pedal applied.
^ Selector lever can be moved from P position with key in ON position and brake pedal released.
^ Selector lever can be moved from P position when key is removed from key cylinder.

SYMPTOM 2:
^ Ignition key cannot be removed when selector lever is set to P position.
^ Ignition key can be removed when selector lever is set to any position except P.

1. CHECK SELECTOR LEVER POSITION
Check the selector lever position for damage.
OK or NG
OK >> GO TO 2.
NG >> Check selector lever. Refer to Adjustment of A/T Position.

2. CHECK SHIFT LOCK SOLENOID AND PARK POSITION SWITCH
1. Connect A/T device harness connector.
2. Turn ignition switch ON.
3. Selector lever is set in P position.





4. Check operation sound.
OK or NG
OK >> INSPECTION END
NG >> GO TO 3.

3. CHECK POWER SOURCE
1. Turn ignition switch ON. (Do not start engine.)
2. Selector lever is set in P position.








3. Check the voltage between A/T device connector M68 terminal 3 (G/R) and ground.
OK or NG
OK >> GO TO 6.
NG >> GO TO 4.

4. CHECK STOP LAMP SWITCH
1. Turn ignition switch OFF.
2. Disconnect stop lamp switch connector.








3. Check continuity between stop lamp switch connector E38 terminals 3 and 4.
Check stop lamp switch after adjusting brake pedal-refer to BRAKE PEDAL.
OK or NG
OK >> GO TO 5.
NG >> Repair or replace damaged parts.

5. DETECT MALFUNCTION ITEM
Check the following items. If any items are damaged, repair or replace damaged parts.
^ Harness for short or open between fuse block (J/B) and stop lamp switch terminal 4 (G/R)
^ Harness for short or open between stop lamp switch terminal 3 (G/R) and A/T device terminal 3 (G/R).
^ 10A fuse [No.12, located in the fuse block (J/B)]
^ Ignition switch. Refer to POWER SUPPLY ROUTING CIRCUIT.
OK or NG
OK >> GO TO 6.
NG >> Repair or replace damaged parts.

6. CHECK A/T DEVICE CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect A/T device connector.








3. Check continuity between A/T device connector M68 terminal 1 and terminal 3.
4. Connect A/T device connector.
OK or NG
OK >> GO TO 7.
NG >> Replace shift lock solenoid or park position switch.

7. CHECK GROUND CIRCUIT





1. Turn ignition switch OFF.
2. Disconnect A/T device connector.
3. Check continuity between A/T device connector M68 terminal 1 (B) and ground.
Continuity should exist.
OK or NG
OK >> Replace shift lock solenoid or park position switch.
NG >> Repair open circuit or short to power in harness or connectors.
