Inspection Procedure

1. Check the wireless door lock control functions (see OPERATION CHECK  ).

   OK: 

   Each function of wireless door lock control system operates normally using transmitter switch. 

NG: Go to step 2 

OK : USE SIMULATION METHOD TO CHECK  (See HOW TO PROCEED WITH TROUBLESHOOTING )

1. Check that the transmitter's LED illuminates 3 times when the switch is pressed 3 times.

   OK: 

   Transmitter's LED illuminates 3 times when switch is pressed 3 times. 

NG:  Go to step  4

OK: Go to next step 

HINT:

Use the following standard test procedure to check the transmitter again.

1. Hold the transmitter approximately 1 m (3.28 ft.) from the driver side door outside handle. The transmitter must be held parallel to the ground and perpendicular to the side of the vehicle.
2. Press and hold either the LOCK or UNLOCK transmitter switch for 1 second, and check that the doors are locked or unlocked accordingly.

   OK: 

   Doors can be locked and unlocked with transmitter switches. 

NG:  Go to step  5

OK: Go to next step 

1. Remove the battery from the inoperative wireless door control transmitter (See REPLACEMENT  ).
2. Measure the voltage according to the value(s) in the table below.

   Standard voltage 

   VOLTAGE SPECIFICATION
   
   

   Tester Connection	Condition	Specified Condition
   Battery positive (+) side - Battery negative (-) side	Always	2.5 to 3.2 V

NG : REPLACE TRANSMITTER BATTERY  (See REPLACEMENT  )

OK : REPLACE DOOR CONTROL TRANSMITTER MODULE  (See REMOVAL  )

1. Check that the room light illumination operates normally.

   OK: 

   Room light operation normally. 

NG: Go to  LIGHTING SYSTEM  .

OK: Go to next step 

1. Switch to self-diagnostic mode by operating the ignition key cylinder
   1. Make sure the vehicle is in its initial condition. Then insert the key into the ignition key cylinder and remove it.
   2. Within 5 seconds of removing the key, insert the key into the ignition key cylinder (ignition switch OFF). Then turn the ignition switch ON and OFF.
   3. Within 30 seconds of turning the ignition switch OFF, perform the following operation 9 times: turn the ignition switch ON and OFF.
      NOTE: If the system cannot enter self-diagnostic mode, the system returns to normal mode.

      HINT:

      • Turning the ignition switch ON after the above operations have been completed ends self-diagnostic mode.
      • Do not lock or unlock doors during self-diagnostic mode.

2. Check that the system has switched to self-diagnostic mode by checking the room light flash pattern.

   OK: 

   Flash pattern is same as illustration. 

NG:  Go to step  13

OK: Go to next step

1. Inspect the diagnosis outputs when the door control transmitter switch is held down. The diagnosis outputs can be checked by the flash patterns of the room light.

   Result: 

   RESULT REFERENCE
   
   

   Result	Proceed to
   Unmatching recognition code is output	A
   Normal waves (light flash patterns) is output	B
   No diagnosis outputs	C

B : REPLACE MAIN BODY ECU 

C:  Go to step  9

A: Go to next step 

1. Check that the system can be switched to rewrite mode or add mode, and that a recognition code can be registered (see REGISTRATION  ).

   OK: 

   Recognition code can be registered. 

NG:  Go to step  16

OK : END 

1. Prepare the door control transmitter of another vehicle.
2. Held down the door control transmitters switch.
3. Check that an unmatching recognition code is output.

   OK: 

   Unmatching recognition code is output. 

NG: Go to step 10 

OK : REPLACE DOOR CONTROL TRANSMITTER MODULE  (See REMOVAL  )

1. Temporarily replace the door lock control receiver with a new or normally functioning one (see REMOVAL  ).

1. Perform the REGISTRATION procedures (see REGISTRATION  ).

1. Check that the doors can be locked and unlocked by using the transmitter LOCK and UNLOCK switches.

   OK: 

   Doors can be locked and unlocked with transmitter. 

NG : REPLACE MAIN BODY ECU 

OK : END (DOOR CONTROL RECEIVER IS DEFECTIVE) 

1. Remove the unlock warning switch (see REMOVAL  ).
2. Measure the resistance according to the value(s) in the table below.

   Standard resistance 

   RESISTANCE SPECIFICATION
   
   

   Tester Connection	Switch Condition	Specified Condition
   1 - 2	Free	10 kΩ or higher
   	Pushed	Below 1 Ω

3. Reconnect the unlock warning switch.

NG : REPLACE UNLOCK WARNING SWITCH ASSEMBLY  (See REMOVAL  )

OK: Go to next step 

1. Disconnect the C6 unlock warning switch connector.
2. Disconnect the 2E main body ECU connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard resistance 

   RESISTANCE SPECIFICATION
   
   

   Tester Connection	Condition	Specified Condition
   2E-23 (KSW) - C6-1	Always	Below 1 Ω
   C6-2 - Body ground
   2E-23 (KSW) or C6-1 -Body ground	Always	10 kΩ or higher

4. Reconnect the unlock warning switch connector.
5. Reconnect the main body ECU connector
