A/T Device Inspection Table





Data are reference value and are measured between each terminal and ground.

Diagnostic Procedure
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 KEY INTERLOCK CABLE
Check key interlock cable for damage.

OK or NG
OK >> GO TO 2.
NG >> Repair key interlock cable. Refer to AT-245. "KEY INTERLOCK CABLE".

2. CHECK SELECTOR LEVER POSITION
Check selector lever position for damage. Refer to "Checking of A/T Position".

OK or NG
OK >> GO TO 3.
NG >> Check selector lever. Refer to "Adjustment of A/T Position".

3. CHECK POWER SOURCE





1. Turn ignition switch "ON". (Do not start engine.)
2. Check voltage between A/T device harness connector terminal 2 and ground.
Voltage: Battery voltage

OK or NG
OK >> GO TO 5.
NG >> GO TO 4.

4. DETECT MALFUNCTIONING ITEM
Check the following.
1. Harness for short or open between ignition switch and A/T device harness connector terminal 2.
2. 10A fuse. [No.12, located in the fuse block (J/B)]
3. Ignition switch. Refer to "POWER SUPPLY ROUTING CIRCUIT".

OK or NG
OK >> GO TO 5.
NG >> Repair or replace damaged parts.

5. CHECK INPUT SIGNAL A/T DEVICE





1. Turn ignition switch "OFF".
2. Disconnect A/T device harness connector.
^ Check voltage between A/T device harness connector terminal 4 and ground.
Voltage:
Depressed brake pedal: Battery voltage
Released brake pedal: Approximately 0 V

OK or NG
OK >> GO TO 7.
NG >> GO TO 6.

6. DETECT MALFUNCTIONING ITEM
Check the following.
1. Harness for short or open between battery and stop lamp switch harness connector terminal 3.
2. Harness for short or open between stop lamp switch harness connector terminal 4 and A/T device harness connector terminal 4.
3. 10A fuse. [No.20, located in the fuse block (J/B)]





4. Stop lamp switch.
- Check continuity between stop lamp switch harness connector terminals 3 and 4. Check stop lamp switch after adjusting brake pedal-refer to "BRAKE PEDAL".

OK or NG
OK >> GO TO 7.
NG >> Repair or replace damaged parts.

7. CHECK GROUND CIRCUIT





1. Turn ignition switch "OFF".
2. Disconnect A/T device harness connector.
3. Check continuity between A/T device harness connector terminal 1 and ground.
Continuity should exist.
If OK, check harness for short to ground and short to power.

OK or NG
OK >> GO TO 8.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.

8. CHECK PARK POSITION SWITCH AND SHIFT LOCK RELAY CIRCUIT (COIL SIDE)





Check continuity between A/T device harness connector terminals 1 and 4.

OK or NG
OK >> GO TO 9.
NG >>
^ Replace park position switch or shift lock relay.
^ Repair open circuit or short to ground or short to power in harness or connectors.

9. CHECK SHIFT LOCK SOLENOID AND SHIFT LOCK RELAY CIRCUIT (SWITCH SIDE)
1. Connect A/T device harness connector.
2. Turn ignition switch "ON". (Do not start engine.)





3. Check shift lock solenoid and shift lock relay operation.

OK or NG
OK >> GO TO 10.
NG >>
^ Replace shift lock solenoid or shift lock relay.
^ Repair open circuit or short to ground or short to power in harness or connectors.

1. CHECK A/T DEVICE INSPECTION
1. Perform A/T device input/output signal inspection test. Refer to "A/T Device Inspection Table".
2. If NG, recheck harness connector connection.

OK or NG
OK >> INSPECTION END
NG >> Repair or replace damaged parts.
