INSPECTION PROCEDURE

OK:

Each function of wireless door lock control system operates normally using transmitter switches (Toyota Fortuner RM000000Z4Y00AX.html).

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.
   

1. After replacing the transmitter battery (Toyota Fortuner RM0000010W9004X.html), check that the doors can be locked and unlocked using the transmitter switches.
   

   OK:

   Doors can be locked and unlocked with transmitter switches (Toyota Fortuner RM000000Z4Y00AX.html).
   

HINT:

Use the following standardized 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 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 lock or unlock, respectively.
   

   OK:

   Doors can be locked and unlocked with transmitter switches (Toyota Fortuner RM000000Z4Y00AX.html).
   

1. Remove the ECU-B and DCC fuses from the engine room relay block.
   

2. Remove the DOOR fuse from the No. 3 relay block.
   

3. Measure the resistance of the fuses.
   

   Standard resistance:

   Below 1 Ω
   

1. Remove the unlock warning switch.
   

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

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   1 - 2	Not pushed	10 kΩ or higher
   	Pushed	Below 1 Ω

1. Disconnect the U1 unlock warning switch connector.
   

2. Disconnect the T36 theft warning ECU connector.
   

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

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   U1-1 - T36-5 (KSW)	Always	Below 1 Ω
   U1-2 - Body ground	Always	Below 1 Ω

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

   OK:

   Recognition code can be registered.
   

1. Disconnect the T36 theft warning ECU connector.
   

   
   
   
   

2. Disconnect the 2A and 2D instrument panel junction block connectors.
   

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

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   T36-21 (L2) - 2A-4 (L1)	Always	Below 1 Ω
   T36-20 (UL3) - 2D-4 (UL1)	Always	Below 1 Ω

1. Disconnect the T36 theft warning ECU connector.
   

2. Measure the resistance and voltage according to the value(s) in the table below.
   

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   T36-1 (E) - Body ground	Always	Below 1 Ω

   Standard Voltage:

   Tester Connection	Condition	Specified Condition
   T36-3 (+B1) - Body ground	Always	11 to 14 V
   T36-12 (+B2) - Body ground	Always	11 to 14 V
