INSPECTION PROCEDURE

NOTICE:

1. Inspect the fuses for circuits related to this system before performing the following inspection procedure.
   
2. When replacing the door control receiver or door control transmitter sub-assembly, refer to the registration procedures (HILUX_TGN26 RM000000Z4Z01LX.html).
   

1. Check the power door lock operation (HILUX_TGN26 RM000004PRU00DX.html).
   

   OK:

   Each door locks and unlocks normally.
   

1. Check whether the wireless door lock control functions operate normally with another registered transmitter.
   

   OK:

   Wireless door lock control functions operate normally.
   

1. Press and hold the lock switch of the door control transmitter assembly for 5 seconds and check the number of times that the transmitter LED illuminates.
   

   Result

   Result	Proceed to
   Transmitter LED does not illuminate when switch is pressed and held	A
   Transmitter LED illuminates 3 times or more when switch is pressed and held	B
   Transmitter LED illuminates once or twice but not third time	C

1. Remove the battery from the door control transmitter assembly that does not operate (HILUX_TGN26 RM000003ZV300OX.html).
   

2. Attach a lead wire (0.6 mm (0.0236 in.) in diameter or less including wire sheath) with tape or equivalent to the negative terminal.
   

   NOTICE:

   Do not wrap the lead wire around a terminal, wedge it between the terminals or solder it. A terminal may be deformed or damaged, and the battery will not be able to be installed correctly.

3. Carefully extend the lead wire out from the position shown in the illustration and install the previously removed transmitter battery.
   

   NOTICE:

   When replacing the transmitter battery, before starting work, remove any static electricity that has built up by touching, for example, the vehicle to prevent the transmitter module set sub-assembly door control from being damaged.

4. Measure the voltage according to the value(s) in the table below.
   

   HINT:

   1. Measure the transmitter battery voltage while pressing the lock or unlock switch on the door control transmitter assembly.
      
   2. Perform the measurement when the door control transmitter assembly is at room temperature.
      

   Standard Voltage:

   Tester Connection	Condition	Specified Condition
   Battery positive (+) - Battery negative (-)	Ignition switch off, all doors closed and lock or unlock switch pushed	2.2 to 3.2 V

1. Move the door control transmitter assembly in the vicinity of the door control receiver.
   

   HINT:

   Refer to Parts Location for the location of the door control receiver (HILUX_TGN26 RM000002XXH00CX.html).

   OK:

   Room No. 1 light illumination operates normally.
   

2. Press and hold either the lock or unlock transmitter switch for 1 second and check that the doors lock or unlock accordingly.
   

   OK:

   Wireless door lock control functions operate normally.
   

   HINT:

   1. Check if electrical noise is the cause by moving the door control transmitter assembly closer to the door control receiver. Moving it closer will decrease the effects of electrical noise.
      
   2. If the operation check can be performed normally, there is a high probability that electrical noise or a decrease in output from the door control transmitter assembly is the cause of the malfunction. There is a high probability that electrical noise is the cause if the problem occurs only in a certain location or only during a certain time of day. Also, custom components may be causing electrical noise. If custom components are installed in the vehicle, remove them and perform the operation check again.
      

1. Disconnect the G82 door lock control receiver connector.
   

2. Disconnect the 2D and 2S driver side junction block assembly connectors.
   

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

   G82-1 (GND) - Body ground	Always	Below 1 Ω

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

   Standard Voltage:

   Tester Connection	Condition	Specified Condition
   G82-5 (+B) - Body ground	Always	11 to 14 V

1. Measure the voltage according to the value(s) in the table below.
   

   Standard Voltage:

   Tester Connection	Condition	Specified Condition
   G82-2 (RDA) - Body ground	Ignition switch off, all doors closed and transmitter switch not pressed	11 to 14 V
   	Ignition switch off, all doors closed and transmitter switch pressed	Pulse generation
