Inspection Procedure

  1. CHECK FOR DTC 
    1. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG) and turn the Techstream ON.
    3. By following the Techstream screen display, check whether any DTCs are output.

    OK: No DTC output.

    B: Go to DIAGNOSTIC TROUBLE CODE CHART  (See DIAGNOSTIC TROUBLE CODE CHART )

    C: Go to DIAGNOSTIC TROUBLE CODE CHART  (See DIAGNOSTIC TROUBLE CODE CHART )

    A: Go to next step 

  2. CHECK MANUAL DOOR LOCK AND UNLOCK OPERATION 
    1. Check that all the doors lock when the door control switch (for manual operation) is turned to LOCK and all doors unlock when turned to UNLOCK.

    OK: All doors can be locked and unlocked with door control switch. 

    NG: Go to POWER DOOR LOCK CONTROL SYSTEM  (See OPERATION CHECK )

    OK: Go to next step 

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

    P-Seat Outside Transmitter Front passenger side door electrical key oscillator ON or OFF -

    OK: When key is brought close to door oscillator that is ON, indicator light on key illuminates. 

    NG: Go to step 4 

    OK: REPLACE ECU AGGREGATION ECU (CERTIFICATION ECU)  (See CERTIFICATION ECU (W/ SMART KEY SYSTEM) )

  4. CHECK WIRE HARNESS (CERTIFICATION ECU - DOOR ELECTRICAL KEY OSCILLATOR) 
    1. Disconnect the E84 ECU connector.
    2. Disconnect the f2 oscillator connector.
    3. Measure the resistance of the wire harness side connectors.

    Standard resistance
