INSPECTION PROCEDURE

1. When the master switch assembly door control switch is operated, check that the locked doors unlock.
   

   OK:

   Door locks operate normally.
   

1. Connect the intelligent tester to the DLC3.
   

2. Turn the engine switch on (IG).
   

3. Turn the intelligent tester on.
   

4. Enter the following menus: Body / Main Body / Data List.
   

5. Read the Data List according to the display on the intelligent tester.
   
   

   Main Body

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   D Door Lock Position SW	Driver side door lock position switch signal / ON or OFF	ON: Driver side door unlocked OFF: Driver side door locked	-

   OK:

   On the intelligent tester screen, the display changes between ON and OFF as shown in the chart above.
   

1. Using the intelligent tester, read the Data List.
   
   

   Entry & Start

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   D-Door Touch Sensor	Driver side door touch sensor / ON or OFF	ON: Touch sensor touched OFF: Touch sensor not touched	-
   D-Door Trigger Switch	Driver side door outside handle lock switch / ON or OFF	ON: Entry lock switch pushed OFF: Entry lock switch not pushed	-

   Result

   Result	Proceed to
   Display changes according to manual operation	A
   Display does not change according to manual operation	B

1. Bring the electrical key transmitter near the driver side door outside handle, and perform a driver side door entry lock and unlock operation check.
   

   NOTICE:

   If the key is brought within 0.2 m (0.656 ft.) of the door handle, communication is not possible.

   HINT:

   1. When the electrical key transmitter is brought near the driver side door outside handle, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
      
   2. If the operation check is normal, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.
      

   Result

   Result	Proceed to
   Operation check fails	A
   Operation check is normal	B

1. Diagnostic mode inspection (driver side door electrical key oscillator).
   

   1. Connect the intelligent tester to the DLC3.
      

   2. Turn the engine switch on (IG).
      

   3. Turn the intelligent tester on.
      

   4. Enter the following menus: Body / Entry & Start / Key Communication Check / Overhead + Driver Side.
      

   5. When the electrical key transmitter is in the position shown in the illustration, check that the wireless door lock buzzer sounds.
      

      HINT:

      If the buzzer sounds, it can be determined that the driver seat outside transmitter is operating normally.

      OK:

      Wireless door lock buzzer sounds.
