Diagnosis Procedure

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM ".

1. PERFORM INITIALIZATION

   Perform initialization with CONSULT. Re-register all mechanical keys.

   For initialization and registration of mechanical key. Refer to "CONSULT Operation Manual".

   Can the system be initialized and can steering lock be released with re-registered mechanical key? 

   YES: Steering lock solenoid was unregistered.

   NO: GO TO 2

2. CHECK STEERING LOCK SOLENOID POWER SUPPLY-1
   1. Turn ignition switch OFF.
   2. Disconnect steering lock solenoid connector.
   3. Check voltage between steering lock solenoid harness connector and ground.

   Terminals			Voltage (V) (Approx.)
   (+)		(-)
   Steering lock solenoid connector	Terminal
   M65	1	Ground	Battery voltage

   Is the inspection result normal? 

   YES: GO TO 3

   NO: Repair or replace harness.

3. CHECK STEERING LOCK SOLENOID GROUND CIRCUIT

   Check continuity between steering lock solenoid harness connector and ground.

   Terminals			Continuity
   (+)		(-)
   Steering lock solenoid connector	Terminal
   M65	4	Ground	Yes

   Is the inspection result normal? 

   YES: GO TO 4

   NO: Repair or replace harness.

4. CHECK STEERING LOCK SOLENOID COMMUNICATION CIRCUITS
   1. Disconnect Intelligent Key unit connector.
   2. Check continuity between steering lock solenoid connector M65 (A) terminals 2, 3 and Intelligent Key unit connector M164 (B) terminals 1, 32.

      Terminals				Continuity
      Steering lock solenoid connector	Terminal	Intelligent Key unit connector	Terminal
      M65	2	M164	1	Yes
      	3		32

   3. Check continuity between steering lock solenoid connector M65 (A) terminals 2, 3 and ground.

   Terminals			Continuity
   Steering lock solenoid connector	Terminals
   M65	2	Ground	No
   	3

   Is the inspection result normal? 

   YES: GO TO 5

   NO: Repair or replace harness.

5. CHECK INTELLIGENT KEY UNIT POWER SUPPLY-2
   1. Connect Intelligent Key unit connector.
   2. Check voltage between Intelligent Key unit harness connector and ground.

   Terminals			Voltage (V) (Approx.)
   (+)		(-)
   Intelligent Key unit connector	Terminal
   M164	1	Ground	5

   Is the inspection result normal? 

   YES: GO TO 6

   NO: Replace Intelligent Key unit. Refer to "REMOVAL AND INSTALLATION ".

6. CHECK STEERING LOCK SOLENOID COMMUNICATION CIRCUIT
   1. Connect steering lock solenoid connector.
   2. Using an oscilloscope, check voltage between Intelligent Key unit connector and ground.

   Terminals			Condition		Voltage (V) (Approx.)
   (+)		(-)
   Intelligent Key unit connector	Terminal
   M164	32	Ground	Steering lock	Ignition knob is pushed
   				LOCK status	5
   				LOCK UNLOCK
   				For 15 seconds after UNLOCK	5
   				15 seconds later UNLOCK	0

   Is the inspection result normal? 

   YES: Replace Steering lock solenoid.

   NO: Replace Intelligent Key unit. Refer to "REMOVAL AND INSTALLATION ".
