Inspection Procedure

  1. CHECK WIRELESS DOOR LOCK CONTROL FUNCTION 
    1. Check the wireless door lock control functions (see OPERATION CHECK  ).

      OK : Each function of wireless door lock control system operates normally using transmitter switches. 

    OK : NORMAL 

    NG : GO TO NEXT STEP 

  2. CHECK THAT TRANSMITTER LED LIGHT UP 
    1. Check that the transmitter's LED illuminates 3 times when the switch is pressed 3 times.

      OK : Transmitter's LED illuminates 3 times when switch is pressed 3 times. 

    NG : Go to step   4 

    OK : GO TO NEXT STEP 

  3. CHECK WIRELESS DOOR LOCK CONTROL FUNCTION (STANDARD OPERATION) 
    1. Check standard UNLOCK/LOCK switch operation.
      NOTE: Standardized test procedures: Press the transmitter switch for 1 second, directing the transmitter to the driver side door outside handle from a distance of 1 m (3.28 ft.). The transmitter should be pointed directly at the handle, i.e. a 90° angle to vehicle body.

      OK : Doors can be locked and unlocked with transmitter. 

    NG : Go to step   5 

    OK : REPLACE DOOR CONTROL TRANSMITTER 

  4. CHECK TRANSMITTER BATTERY (OPERATION) 
    1. Temporarily replace the transmitter battery with a new or normally functioning one.
    2. Check that the doors can be locked and unlocked by using the transmitter LOCK/UNLOCK switch.

      OK : Doors can be locked and unlocked with transmitter switch. 

    NG : REPLACE DOOR CONTROL TRANSMITTER 

    OK : END (TRANSMITTER BATTERY IS DEFECTIVE) 

  5. SWITCH TO SELF-DIAGNOSTIC MODE 
    1. Switch to self diagnostic mode using the intelligent tester.
      1. Connect the intelligent tester (with CAN VIM) to the DLC3.
      2. Turn the power switch ON (IG) and push the intelligent tester main switch ON.

        HINT:

        Please refer to the intelligent tester operator's manual for further details.

    2. Switch to self diagnostic mode by operating the key.
      1. Put the vehicle under the vehicle's initial condition (see OPERATION CHECK  ), insert the key into the key slot and remove it.
      2. Within 5 seconds of removing the key (above step), insert the key into the key slot. Then turn the power switch ON (IG) and OFF.
      3. Within 30 seconds of switching the power switch OFF (step above), perform the following 9 times:. Turn the power switch ON (IG) and OFF*
        NOTE: If the change to self diagnostic mode has failed, the system will return to normal mode.

        HINT:

        • Turning the power switch ON (IG) after step * has been completed will end self-diagnostic mode.
        • Do not lock or unlock doors during the self-diagnostic mode.
    3. Check that the system has switched to self diagnostic mode by checking the flashes of the room light (dome light or key slot light). Compare the flash patterns of the room light to the timing chart on the illustration.

      OK : Flash pattern of room light should be the same as that shown in timing chart on illustration. 

    NG : Go to step   9 

    OK : GO TO NEXT STEP 

  6. CHECK BY SELF-DIAGNOSTIC MODE 
    1. Inspect the diagnosis outputs when the door control transmitter switch is held down. The diagnosis outputs can be checked by flash patterns of the room light.

      Result: 

      RESULT REFERENCE

      Result Proceed to
      Unmatched recognition code is output A
      Normal waves (patterns of room light) for LOCK, UNLOCK and PANIC switches are output B
      No diagnosis outputs are present C

    B : REPLACE DRIVER SIDE JUNCTION BLOCK ASSEMBLY (MAIN BODY ECU) 

    C : Go to step   8 

    A : Go to next step 

  7. REGISTER RECOGNITION CODE 
    1. Check that the system can switch to rewrite mode or add mode and recognition code can be registered.

      OK : System can switch to rewrite mode or add mode and recognition code can be registered. 

    NG : Go to step   15 

    OK : END 

  8. CHECK DOOR CONTROL RECEIVER (RESPONSE) 
    1. Temporarily replace the door control receiver with a new or normally functioning one.
    2. Check that an unmatching recognition code is output when the door lock control transmitter switch is held down.

      OK : Unmatching recognition code is output. 

    NG : Go to step   12 

    OK : REPLACE DOOR CONTROL TRANSMITTER 

  9. CONFIRM INPUT METHOD OF SELF-DIAGNOSTIC MODE 

    Result: 

    RESULT REFERENCE

    Result Proceed to
    Method for changing system self diagnostic mode works A
    Method for changing system self diagnostic mode does not work B

    B : Go to step   5 

    A : Go to next step 

  10. INSPECT KEY SLOT 
    1. Measure the resistance of the halfway switch.
