DESCRIPTION

When an ID code from the door electrical key oscillator (back door) matches the ID code from the key, the certification ECU outputs an SEL signal (Lo when output) to the door electrical key oscillator (back door), activates the touch sensor located on the backside of the outside door handle, and enters unlock standby mode. When the touch sensor is touched, the door electrical key oscillator (back door) sends an SENS signal (Lo when output) to the certification ECU and the certification ECU sends an unlock signal to the back door lock.

INSPECTION PROCEDURE

1.CHECK FOR DTC
  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch on (IG) and turn the tester ON.

  1. By following the tester screen display, check whether any DTCs are output.

    OK:
    No DTC output.


NG
Go to DIAGNOSTIC TROUBLE CODE CHART
OK


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

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


NG
Go to POWER DOOR LOCK CONTROL SYSTEM
OK


3.CHECK WIRELESS DOOR LOCK CONTROL OPERATION
  1. Check that the wireless door lock and unlock functions operate normally (RAV4_ACA30 RM000001VRW002X.html).

    OK:
    Wireless door lock and unlock functions operate normally.


NG
Go to WIRELESS DOOR LOCK CONTROL SYSTEM (w/ ENTRY AND START SYSTEM)
OK


4.READ VALUE USING INTELLIGENT TESTER (DOOR COURTESY SWITCH)
  1. Check the Data List for proper functioning of the back door courtesy light switch.

    Main body ECU:
    Item
    Measurement Item / Range (Display)
    Normal Condition
    Diagnostic Note
    Back Door Courtesy SW
    Back door courtesy light switch signal / ON or OFF
    ON: Back door is open
    OFF: Back door is closed
    -
    OK:
    On tester screen, item changes between ON and OFF according to above chart.


NG
Go to LIGHTING SYSTEM
OK


5.PERFORM ACTIVE TEST USING INTELLIGENT TESTER (BACK DOOR SELECT)
  1. Select the Active Test, use the intelligent tester to generate a control command, and then check that the door electrical key oscillator operates.

    Certification ECU:
    Item
    Test Details
    Diagnostic Note
    Back Door Select
    Door electrical key oscillator (back door) ON / OFF
    -
    OK:
    ON (Outside Trunk/Backdoor Transmitter is ON) appears on screen.


NG
REPLACE ECU AGGREGATION BOX (CERTIFICATION ECU)
OK


6.READ VALUE USING INTELLIGENT TESTER (BACK DOOR UNLOCK SWITCH)
  1. With "Back Door Select" ON, check the Data List to confirm the operation of the touch sensor.

    Certification ECU:
    Item
    Measurement Item / Range (Display)
    Normal Condition
    Diagnostic Note
    B-Door Touch Sensor
    Back door touch sensor / ON or OFF
    ON: Sensor touch is touched
    OFF: Sensor touch is not touched
    -
    OK:
    When back door sensor is set to ON, ON (sensor is touched) appears on screen.


NG
Go to step 8
OK


7.CHECK INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY (OPERATION)
  1. Temporarily replace the instrument panel junction block (main body ECU) with a new or normally functioning one.

  1. Check that the entry back door unlock function operates normally.

    OK:
    Entry back door unlock function operates normally.


NG
REPLACE INSTRUMENT PANEL JUNCTION BLOCK (MAIN BODY ECU)
OK

END (CERTIFICATION ECU IS DEFECTIVE)

8.CHECK DOOR ELECTRICAL KEY OSCILLATOR (for Back Door)
Toyota Rav4. Aca30, 33, 38 Gsa33 Zsa30, 35.Door Lock.Power Door Lock Control System.Entry And Start System  Back Door Entry Unlock Function Does Not Operate
  1. Measure the resistance of the oscillator.

    Standard voltage:
    Tester Connection
    Condition
    Specified Condition
