2. Disconnect the oscillator connectors.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Inside Luggage Compartment 

   Outside Luggage Compartment 

   Tester Connection (Symbols)	Condition	Specified Condition
   E13-16 (CG7B) - R2-3 (CLGB)	Always	Below 1 Ω
   E13-15 (CLG7) - R2-1 (CLG6)	Always	Below 1 Ω
   E13-16 (CG7B) - Body ground	Always	10 kΩ or higher
   E13-15 (CLG7) - Body ground	Always	10 kΩ or higher

   Tester Connection (Symbols)	Condition	Specified Condition
   E13-32 (CG8B) - R3-2 (CLGB)	Always	Below 1 Ω
   E13-31 (CLG8) - R3-1 (CLG5)	Always	Below 1 Ω
   E13-32 (CG8B) - Body ground	Always	10 kΩ or higher
   E13-31 (CLG8) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

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

   OK

   Luggage compartment door entry LOCK/UNLOCK function operates normally.

OK → END (ELECTRICAL KEY OSCILLATOR IS DEFECTIVE) 

NG: Go to next step 

1. Reconnect the oscillator and the ECU 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 Access / Active Test.
6. Perform the Active Test according to the display on the tester.
   SMART ACCESS:
   
   

   Tester Display	Test Part	Control Range	Diagnostic Note
   In-Bdr Transmitter	Luggage compartment door inner oscillator	ON/OFF	-
   Bdoor Transmitter	Luggage compartment door outer oscillator	ON/OFF	-

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