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 Immobilizer mode and follow the on-screen instructions.

   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 STEP 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
      M15	1	Ground	Battery voltage

   Is the inspection result normal?

   YES 

   GO TO STEP 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
   M15	4	Ground	Yes

   Is the inspection result normal?

   YES 

   GO TO STEP 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 (A) M15 terminals 2, 3 and Intelligent Key unit connector (B) M70 terminals 1, 32.

      Steering lock solenoid connector	Terminal	Intelligent Key unit connector	Terminal
      A M15	2	B M70	1	Yes
      	3		32

   3. Check continuity between steering lock solenoid connector (A) M15 terminals 2, 3 and ground.

      Terminals			Continuity
      Steering lock solenoid connector	Terminals
      A M15	2	Ground	No
      	3

   Is the inspection result normal?

   YES 

   GO TO STEP 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.

      M70	1	Ground	5

   Is the inspection result normal?

   YES 

   GO TO STEP 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.
