Diagnosis ProcedureINFOID:0000000001728307
SYMPTOM 1:
Selector lever cannot be moved from “P” position with ignition switch in ON position and brake
pedal depressed.
Selector lever can be moved from “P” position with ignition key in ON position and brake pedal
released.
Selector lever can be moved from “P” position when ignition switch 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” position.
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 TM-206, "
Removal and Installation" .
2.CHECK A/T POSITION
Check A/T position. Refer to TM-204, "
Checking of A/T Position" .
OK or NG
OK >> GO TO 3.
NG >> Adjust control cable. Refer to TM-204, "
Adjustment of A/T Position" .
3.CHECK SHIFT LOCK SOLENOID AND PARK POSITION SWITCH
1. Turn ignition switch ON. (Do not start engine.)
2. Selector lever is set in “P” position.
3. Check operation sound.
OK or NG
OK >>INSPECTION END
NG >> GO TO 4.
4.CHECK POWER SOURCE
1. Turn ignition switch ON. (Do not start engine.)

2. Check voltage between A/T device harness connector terminal
5 and ground.
OK or NG
OK >> GO TO 7.
NG >> GO TO 5.
5.CHECK STOP LAMP SWITCH
1. Turn ignition switch OFF.
2. Disconnect stop lamp switch harness connector.
3. Check continuity between stop lamp switch harness connector
terminals 3 and 4.
Check stop lamp switch after adjusting brake pedal. Refer to
BR-6, "
Inspection and Adjustment" .
OK or NG
OK >> GO TO 6.
NG >> Repair or replace damaged parts.
6.DETECT MALFUNCTIONING ITEM
Check the following. If any items are damaged, repair or replace damaged parts.
Harness for short or open between ignition switch and stop lamp switch harness connector
Harness for short or open between stop lamp switch harness connector and A/T device harness connector
10A fuse [No. 3, located in the fuse block (J/B)]
Ignition switch.
OK or NG
OK >>INSPECTION END
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 termi-
nal 6 and ground.
4. Connect A/T device harness connector.
OK or NG
OK >> Replace shift lock solenoid and park position switch
assembly.
NG >> Repair open circuit or short to ground or short to power
in harness or connectors. Voltage:
Brake pedal depressed: Battery voltage
Brake pedal released: 0V
