NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to next step
- CHECK AND REPLACE ELECTRICAL KEY OSCILLATOR (CHECK OPERATION OF OSCILLATOR)
- Replace the door oscillator.
- Check that the entry LOCK/UNLOCK function operates normally.
OK
Entry LOCK/UNLOCK function operates normally.
OK → END (ELECTRICAL KEY OSCILLATOR IS DEFECTIVE)
NG: Go to next step
- PERFORM ACTIVE TEST USING TECHSTREAM (CERTIFICATION ECU OUTPUT SIGNAL)
- Reconnect the ECU and the oscillator connectors.
- Connect Techstream to the DLC3.
- Turn the engine switch on (IG).
- Turn the tester on.
- Enter the following menus: Body Electrical/Smart Access/Active Test.
- Perform the Active Test according to the display on the tester.SMART ACCESS:
