Inspection Procedure

  1. CHECK ENTRY DOOR LOCK AND UN LOCK OPERATION 
    1. Check that the entry lock and unlock functions operate normally.

      OK : Entry lock and unlock functions operate normally 

    NG : GO TO PROBLEM SYMPTOMS TABLE 

    OK : GO TO NEXT STEP 

  2. READ VALUE OF TECHSTREAM (HALFWAY SWITCH) 
    1. Check the DATA LIST for proper functioning of the halfway switch.

      Item Measurement Item / Range (Display) Normal Condition Diagnostic Note
      KEY UNLK WRN SW Key unlock warning switch /
      ON or OFF      		 OK: Key is in key slot
      OFF: No key is in key slot      		 -

      OK : ON (key is in key slot) appears on screen. 

    NG : GO TO SMART KEY SYSTEM (for starting) 

    OK : GO TO NEXT STEP 

  3. PERFORM ACTIVE TEST BY TECHSTREAM (INDOOR ELECTRICAL KEY OSCILLATOR) 
    1. Select the ACTIVE TEST, use the Techstream to generate a control command, and then check that the oscillator operates.

      Item Tester Details Diagnostic Note
      FR TRANSMITTER Indoor electrical key oscillator (front)
      ON / OFF      		 -

      OK : When key is brought close to indoor electrical key oscillator, oscillator is turned ON and indicator on key illuminates. 

    OK : REPLACE CERTIFICATION ECU 

    NG : GO TO NEXT STEP 

  4. INSPECT FUSE (MPX-B, D/C CUT) 
    1. Remove the MPX-B and D/C CUT fuses from the engine room relay block.
    2. Measure the resistance of the fuses.

      Standard resistance: Below 1 Ω 

    NG : REPLACE FUSE 

    OK : GO TO NEXT STEP 

  5. CHECK WIRE HARNESS (INDOOR ELECTRICAL KEY OSCILLATOR - BATTERY AND BODY GROUND) 
    1. Disconnect the R8 oscillator connector.
    2. Measure the voltage of the wire harness side connector.

      Standard voltage 

      TESTER CONNECTION SPECIFIED CONDITION

      Tester Connection Specified Condition
      R8-1 (+B) - Body ground 10 to 14 V
    3. Measure the resistance of the wire harness side connector.

      Standard resistance 

      TESTER CONNECTION SPECIFIED CONDITION

      Tester Connection Specified Condition
      R8-5 (GND) - Body ground Below 1 Ω

    NG : REPAIR OR REPLACE HARNESS AND CONNECTOR

    OK : GO TO NEXT STEP 

  6. CHECK WIRE HARNESS (INDOOR ELECTRICAL KEY OSCILLATOR - CERTIFICATION ECU) 
    1. Disconnect the R8 oscillator connectorsa.
    2. Disconnect the S11 ECU connector.
    3. Measure the resistance of the wire harness side connectors.

      Standard resistance 

      TESTER CONNECTION SPECIFIED CONDITION

      Tester Connection Specified Condition
      R8-3 (CLG3) - S11-36 (CLG5) Below 1 Ω
      R8-3 (CLG3) or S11-36 (CLG5) - Body ground 10 kΩ or higher

    NG : REPAIR OR REPLACE HARNESS AND CONNECTOR

    OK : GO TO NEXT STEP 

  7. CHECK INDOOR ELECTRICAL KEY OSCILLATOR (CLG3 VOLTAGE) 
    1. Measure the voltage of the oscillator connector.

      Standard voltage 

      TESTER CONNECTION SPECIFIED CONDITION

      Tester Connection Condition Specified Condition
      R8-3 (CLG3) - R8-5 (GND) During Active Test Alternating between 5 V and below 1 V

    NG : REPLACE INDOOR ELECTRICAL KEY OSCILLATOR
