NG: REPAIR OR REPLACE HARNESS OR CONNECTOR

OK: Go to next step

CHECK AND REPLACE ELECTRICAL KEY OSCILLATOR (CHECK OPERATION OF OSCILLATOR)
1. Replace the door oscillator.
2. 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 BY 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:

SMART ACCESS ACTIVE TEST REFERENCE

Tester Display	Test Part	Control Range
D Transmitter	Driver door electrical key oscillator	ON/OFF
P Transmitter	Passenger door electrical key oscillator	ON/OFF
DR Transmitter	Rear door electrical key oscillator RH	ON/OFF
PR Transmitter	Rear door electrical key oscillator LH	ON/OFF

Measure the frequency according to the value(s) in the table below.

Standard:

Front LH side
