DESCRIPTION

INSPECTION PROCEDURE

NOTICE:

1. The entry and start system (for entry function) uses a multiplex communication system (LIN communication system) and CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting (CAMRY_ACV40 RM000000XU703SX.html). Troubleshoot the entry and start system (for entry function) after confirming that the communication system is functioning properly.
   
2. Check that there are no electrical key transmitters in the vehicle.
   

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 / Data List.
   

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

   Result:

   Result	Proceed to
   Entry function cancel is OFF	A
   Entry function cancel is ON	B

1. Move the electrical key transmitter as described below and perform the operation inspection.
   

   HINT:

   1. When the electrical key transmitter is brought near the door outside handle assembly or electrical key antenna, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
      
   2. The transmitting waves of the wireless functions and entry functions are the same, but the wave logic is different. Therefore, it is possible that only the wireless functions or only the entry functions are affected by wave interference.
      

2. Bring the electrical key transmitter near the front door outside handle assembly (for driver side), and perform a front driver door entry lock and unlock operation check.
   

   HINT:

   When pressing the lock switch, hold the electrical key transmitter about 1 m (3.28 ft.) above the ground and about 0.3 m (0.984 ft.) away from the vehicle as shown in the illustration.

   NOTICE:

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

3. Bring the electrical key transmitter near the front door outside handle assembly (for front passenger side), and perform a front passenger door entry lock and unlock operation check.
   

   HINT:

   When pressing the lock switch, hold the electrical key transmitter about 1 m (3.28 ft.) above the ground and about 0.3 m (0.984 ft.) away from the vehicle as shown in the illustration.

   NOTICE:

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

4. Bring the electrical key transmitter near the outside electrical key oscillator (for luggage compartment), and perform an entry luggage compartment door open function check.
   

   HINT:

   When pressing the luggage compartment door opener outer switch, hold the electrical key transmitter about 1 m (3.28 ft.) above the ground and about 0.3 m (0.984 ft.) away from the vehicle as shown in the illustration.

   NOTICE:

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

   HINT:

   If the inspection result is that the problem only occurs in certain locations or times of day, 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
   All operation checks fail	A
   Some operation checks are normal	B
