DESCRIPTION

1. for LHD:
   When an ID code from the door electrical key oscillator LH matches the ID code from the key, the certification ECU outputs an SEL signal (Lo when output) to the door electrical key oscillator LH, 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 LH sends a SENS signal (Lo when output) to the certification ECU and the certification ECU sends an unlock signal to the driver side door lock.
   

1. for RHD:
   When an ID code from the door electrical key oscillator RH matches the ID code from the key, the certification ECU outputs an SEL signal (Lo when output) to the door electrical key oscillator RH, 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 RH sends a SENS signal (Lo when output) to the certification ECU and the certification ECU sends an unlock signal to the driver side door lock.

INSPECTION PROCEDURE

1. Connect the intelligent tester to the DLC3.
   

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

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

   OK:

   No DTC output.
   

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.
   

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.
   

1. Check the Data List to confirm the operation of the door courtesy light switch (driver side).
   
   

   Main body ECU:

   Item	Measurement Item / Range (Display)	Normal Condition	Diagnostic Note
   D Door Courtesy SW	Driver side door courtesy light switch signal ON / OFF	ON: Driver side door is open OFF: Driver side door is closed	-

   OK:

   On tester screen, item changes between ON and OFF according to above chart.
   

1. Connect the intelligent tester to the DLC3.
   

2. Turn the ignition switch on (IG).
   

3. Turn the intelligent tester on.
   

4. Enter the following menus: Body / Main Body / Data List.
   

5. Read the Data List according to the display on the intelligent tester.
   
   

   Main body ECU:

   Item	Measurement Item / Range (Display)	Normal Condition	Diagnostic Note
   D-Door Lock Pos SW	Driver side door lock position switch signal / ON or OFF	ON: Driver side door is unlocked OFF: Driver side door is closed	-

   OK:

   On the intelligent tester screen, the display changes between ON and OFF as shown in the chart above.
   

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
   D-Seat Select	Driver side electrical key oscillator ON / OFF	-

   OK:

   ON (D-Seat Select is ON) appears on screen.
   

1. With "D-Seat Select" ON, check the Data List to confirm the operation of the touch sensor (driver side).
   
   

   Certification ECU:

   Item	Measurement Item / Range (Display)	Normal Condition	Diagnostic Note
   D-Door Touch Sensor	Driver side door touch sensor / ON or OFF	ON: Sensor is touched OFF: Sensor is not touched	-

   OK:

   When driver side door touch sensor is set to ON, ON (sensor is touched) appears on screen.
   

1. Temporarily replace the ECU aggregation box (certification ECU) with a new or normally functioning one.
   

2. Check that the entry unlock function operates normally (RAV4_ACA30 RM000001VGF003X.html).
   

   OK:

   Entry unlock function operates normally.
   

1. Measure the voltage of the oscillator.
   

   Standard voltage:

   Tester Connection	Condition	Specified Condition
   4 (SEL) - Body ground	During Active Test	Below 1 V
   6 (SENS) - Body ground	Touch sensor is touched during Active Test	Below 1 V
   	Touch sensor is not touched during Active Test	10 to 14 V

1. Disconnect the Z2*1 or Y2*2 oscillator connector.
   

2. Disconnect the Z1*1 or Y1*2 antenna connector.
   

3. Measure the resistance of the wire harness side connectors.
   

   HINT:

   *1: for LHD

   *2: for RHD
