2. Measure the resistance between the oscillator and the certification ECU to check for an open circuit in the wire harness.

   Resistance: 

   Below 1 Ω 

3. Measure the resistance between the oscillator and the certification ECU to check for an short circuit in the wire harness.

   Resistance: 

   10 kΩ or higher 

   HINT:

   Refer to the WIRING DIAGRAM  for connection of each terminal.

NG: REPAIR OR REPLACE HARNESS AND CONNECTOR 

OK: Go to next step 

1. Reconnect the ECU and the oscillator connectors.
2. Connect Techstream to the DLC3.
3. Turn the engine switch on (IG).
4. Turn the tester on.
5. Enter the following menus: Body Electrical / Smart Key / Active Test.
6. Perform the Active Test according to the display on the tester.

OK : PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE 

NG: Go to next step 

1. Replace the door oscillator.
2. Check that the entry LOCK / UNLOCK function operates normally.

   OK: 

   Entry LOCK / UNLOCK function operates normally.
