INSPECTION PROCEDURE

NOTICE:

1. When replacing the door control receiver, read the transmitter IDs (tire pressure warning system) stored in the old ECU using the Techstream and write them down before removal (YARIS_NCP93 RM000000XN107WX.html).*1
   
2. It is necessary to perform initialization (YARIS_NCP93 RM000000XMZ073X.html) after registration (YARIS_NCP93 RM000000XN107WX.html) of the transmitter IDs into the door control receiver if the door control receiver has been replaced.*1
   
3. When replacing or inspecting the door control receiver and wire harness, do not change the position or length of the wire harness. If the wire harness is too close to the door control receiver and wireless function performance may be affected.
   
4. Inspect the fuses for circuits related to this system before performing the following inspection procedure.
   
1. *1: w/ Tire Pressure Warning System
   

1. When the door control switch on the power window regulator master switch assembly is operated, check that the locked doors unlock (YARIS_NCP93 RM000002T6K03IX.html).
   

OK:

Locked doors unlock.

1. Check that the key reminder warning buzzer operates normally (YARIS_NCP93 RM00000133203NX.html).
   

   OK:

   Key reminder warning buzzer operates normally.
   

1. Switch to self-diagnostic mode.
   

   1. Connect the Techstream to the DLC3.
      

   2. Turn the ignition switch to ON.
      

   3. Turn the Techstream on.
      

   4. Enter following menus: Body Electrical / Main Body / Utility / Wireless Door Lock Diagnosis Mode
      

   5. Proceed to the next step in accordance with the prompts on the Techstream screen.
      

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

   OK:

   Flash pattern is same as illustration on left.
   

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 map light assembly.
   

   
   
   
   
   

   Result

   Result	Proceed to
   Normal waves (light flash patterns) for lock and unlock switches are output	A
   Unmatching recognition code is output	B
   No diagnosis outputs	C

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. Prepare the door control transmitter from another vehicle.
   

2. Press and hold down the door control transmitter switch.
   

3. Check that an unmatching recognition code is output.
   

OK:

Unmatching recognition code is output.

1. w/o Tire Pressure Warning System
   

   1. Remove the battery from the door control transmitter module that does not operate. Attach a lead wire (0.6 mm (0.0236 in.)) or less in diameter including wire sheath) with tape or equivalent to the negative terminal (YARIS_NCP93 RM000002X5Z011X.html).
      

      NOTICE:

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

   
   
   

   2. Carefully pull 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 door control transmitter module set from being damaged.

      Standard Voltage:

      Tester Connection	Condition	Specified Condition
      Battery positive (+) - Battery negative (-)	Ignition switch off, all doors closed and lock or unlock switch pushed	2.5 to 3.2 V

2. w/ Tire Pressure Warning System
   

   1. Remove the battery from the door control transmitter module that does not operate. Attach a lead wire (0.6 mm (0.0236 in.)) or less in diameter including wire sheath) with tape or equivalent to the negative terminal (YARIS_NCP93 RM000002X5Z011X.html).
      

      NOTICE:

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

1. Replace the transmitter battery (YARIS_NCP93 RM000002X5Z011X.html).
   

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 No. 1 room light assembly.
   

   
   
   
   
   

   Result

   Result	Proceed to
   Normal waves (light flash patterns) for LOCK and UNLOCK switches are output	A
   Unmatching recognition code is output	B
   No diagnosis outputs

1. Bring the transmitter near the door control receiver, and perform a wireless operation check.
   

   OK:

   Wireless functions operate normally.
   

   HINT:

   1. When the transmitter is brought near the door control receiver, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
      
   2. 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.
