Inspection Procedure

HINT:

When the engine switch is off, the main body ECU may occasionally go into a non-active state called sleep mode. Therefore, before proceeding with the inspection, it is necessary to perform the following step to wake up the ECU:

With the engine switch off, open the driver door. Then (with the engine switch still off) open and close any door several times at 1.5 second intervals.

1. INSPECT FUSE (STR LOCK) 
   1. Remove the STR LOCK fuse from the main body ECU.
   2. Measure the resistance of the fuse.

      Standard Resistance 

      RESISTANCE SPECIFICATION
      
      

      Tester Connection	Condition	Specified Condition
      STR LOCK fuse	Always	Below 1 Ω

   NG: REPLACE FUSE 

   OK: Go to next step 

2. CHECK HARNESS AND CONNECTOR (STEERING LOCK ACTUATOR - BODY GROUND) 
   1. Disconnect the L33 steering lock actuator connector.
   2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance 

      RESISTANCE SPECIFICATION
      
      

      Tester Connection	Condition	Specified Condition
      L33-1 (GND) - Body ground	Always	Below 1 Ω
      L33-2 (SGND) - Body ground	Always	Below 1 Ω

   NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

   OK: Go to next step 

3. CHECK HARNESS AND CONNECTOR (BATTERY - STEERING LOCK ACTUATOR) 
   1. Disconnect the L33 steering lock actuator connector.
   2. Measure the voltage according to the value(s) in the table below.

      Standard Voltage 

      VOLTAGE SPECIFICATION
      
      

      Tester Connection	Condition	Specified Condition
      L33-7 (B) - Body ground	Always	11 to 14 V
