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.
WIRING DIAGRAM
INSPECTION PROCEDURE
Connect the intelligent tester to the DLC3.
Turn the ignition switch on (IG) and turn the tester ON.
By following the tester screen display, check whether any DTCs are output.
- OK:
- No DTC output.
| | Go to DIAGNOSTIC TROUBLE CODE CHART |
|
|
| 2.CHECK MANUAL DOOR UNLOCK OPERATION |
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.
| | Go to POWER DOOR LOCK CONTROL SYSTEM |
|
|
| 3.CHECK WIRELESS DOOR LOCK CONTROL OPERATION |
Check that the wireless door lock and unlock functions operate normally (RAV4_ACA30 RM000001VRW002X.html).
- OK:
- Wireless door lock and unlock functions operate normally.
| | Go to WIRELESS DOOR LOCK CONTROL SYSTEM (w/ ENTRY AND START SYSTEM) |
|
|
| 4.READ VALUE USING INTELLIGENT TESTER (DOOR COURTESY SWITCH) |
Check the Data List for proper functioning of the back door courtesy light switch.

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.
| 7.CHECK INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY (OPERATION) |
Temporarily replace the instrument panel junction block (main body ECU) with a new or normally functioning one.
Check that the entry back door unlock function operates normally.
- OK:
- Entry back door unlock function operates normally.
| | REPLACE INSTRUMENT PANEL JUNCTION BLOCK (MAIN BODY ECU) |
|
|
| OK |
|
|
|
| END (CERTIFICATION ECU IS DEFECTIVE) |
|
