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. When the door control switch on the master switch assembly is operated, check that the locked doors unlock (CAMRY_ACV40 RM00000133302LX.html).
   

   OK:

   Locked doors unlock.
   

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.
   
   

   Entry & Start (Certification ECU (Smart Key ECU Assembly))

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   P Touch Sensor	Front passenger side door touch sensor / ON or OFF	ON: Touch sensor is touched OFF: Touch sensor is not touched	-
   P Trigger SW	Front passenger side door lock switch / ON or OFF	ON: Entry lock switch is pressed OFF: Entry lock switch is not pressed	-

   OK:

   On the intelligent tester screen, the display changes between ON and OFF according to the chart above.
   

1. 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.
   

   NOTICE:

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

   HINT:

   1. 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.
      
   2. When the electrical key transmitter is brought near the front door outside handle assembly (for front passenger side), the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
      
   3. If the inspection result is that 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.
      

   OK:

   Entry functions operate normally.
   

1. Diagnostic mode inspection (door electrical key oscillator (for front passenger side))
   

   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 / Utility / Key Communication Check / Overhead + Passenger Side.
      

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

      HINT:

      1. If the buzzer sounds, it can be determined that the door electrical key oscillator (for front passenger side) is operating normally.
         
      2. Hold the electrical key transmitter at the same height as the door outside handle (0.7 to 1.0 m (2.30 to 3.28 ft.)). Make sure that the direction of the key is as shown in the illustration.
         

      OK:

      Wireless door lock buzzer sounds.
      

1. Disconnect the certification ECU (smart key ECU assembly) connector.
   

2. Disconnect the door electrical key oscillator (for front passenger side) connector.
   

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