### WIRELESS DOOR LOCK CONTROL SYSTEM > Only Wireless Control Function is Inoperative

## DESCRIPTION

The door control receiver receives signals from the transmitter and sends these signals to the instrument panel junction block (integration relay). The instrument panel junction block (integration relay) then controls all doors by sending lock / unlock signals to each door and hazard flasher relay signals to the turn signals flasher relay (hazard warning lights).

## WIRING DIAGRAM

## INSPECTION PROCEDURE

1.CHECK WIRELESS DOOR LOCK CONTROL FUNCTIONS

OK:
  Each function of wireless door lock control system operates normally using transmitter switches (Click here).

| OK |

END

NG |

2.CHECK THAT TRANSMITTER LED ILLUMINATES

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 |

3.CHECK WIRELESS DOOR LOCK CONTROL FUNCTION (STANDARD OPERATION FUNCTION)

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.

1. 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 (Click here).

| NG |

Go to step 5

OK |

REPLACE DOOR CONTROL TRANSMITTER MODULE

4.REPLACE TRANSMITTER BATTERY

1. After replacing the transmitter battery (Click here), check that the doors can be locked and unlocked using the transmitter switches.

   OK:
     Doors can be locked and unlocked with transmitter (Click here).

| NG |

REPLACE DOOR CONTROL TRANSMITTER MODULE

OK |

END (TRANSMITTER BATTERY DEFECTIVE)

5.CHECK NO.1 ROOM LIGHT ASSEMBLY

1. Check that the No. 1 room light assembly illumination operates normally.

   OK:
     No. 1 room light assembly illumination operates normally.

| NG |

Go to LIGHTING SYSTEM

OK |

6.SWITCH TO SELF-DIAGNOSTIC MODE

1. Switch to self-diagnostic mode by operating the ignition key cylinder.

   1. Make sure the vehicle is in its initial condition (Click here). 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 9 times: turn the ignition switch ON and OFF.

      NOTICE:
        If the change to self-diagnostic mode has failed, the system will return to normal mode.

      HINT:
      1. Turning the ignition switch to ON after the above operations have been completed will end self-diagnostic mode.
      2. Do not lock or unlock doors during self-diagnostic mode.

1. Check that the system has switched to self-diagnostic mode by checking the No. 1 room light assembly flash pattern.

   OK:
     Flash pattern should be same as illustration on left.

| NG |

Go to step 11

OK |

7.CHECK BY SELF-DIAGNOSTIC MODE

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
   Unmatching recognition code is output | A
   Normal waves (light flash patterns) for LOCK and UNLOCK switches are output | B
   No diagnosis outputs are present | C

| B |

REPLACE INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY (INTEGRATION RELAY)

| C |

Go to step 9

A |

8.REGISTER RECOGNITION CODE

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.

| NG |

Go to step 15

OK |

END

9.CHECK RESPONSE OF DOOR CONTROL RECEIVER

1. When a new or normally functioning door lock control transmitter switch for the same type vehicle is held down, check that an unmatching recognition code is output.

   OK:
     Unmatching recognition code is output.

| OK |

REPLACE DOOR CONTROL TRANSMITTER MODULE

NG |

10.REPLACE DOOR CONTROL RECEIVER

1. After replacing the door control receiver (Click here), check that the doors can be locked and unlocked by using the transmitter LOCK / UNLOCK switch.

   OK:
     Doors can be locked and unlocked with transmitter.

| NG |

REPLACE INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY (INTEGRATION RELAY)

OK |

END

11.CONFIRM INPUT METHOD OF SELF-DIAGNOSTIC MODE

Result:
Result | Proceed to
Method for changing system to self-diagnostic mode works | A
Method for changing system to self-diagnostic mode does not work | B

| B |

Go to step 6

A |

12.INSPECT UNLOCK WARNING SWITCH ASSEMBLY

1. Remove the switch.

1. Measure the voltage and resistance of the switch.

   Standard resistance:

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

| NG |

REPLACE UNLOCK WARNING SWITCH ASSEMBLY

OK |

13.CHECK WIRE HARNESS (DOOR CONTROL RECEIVER - INSTRUMENT PANEL JUNCTION BLOCK)

1. Disconnect the D10 receiver connector.

1. Disconnect the 2D junction block connector.

1. Measure the resistance of the wire harness side connectors.

   Standard resistance:

     Tester Connection | Specified Condition
     D10-3 (PRG) - 2D-2 | Below 1 Ω
     D10-2 (RDA) - 2D-5 | Below 1 Ω

| NG |

REPAIR OR REPLACE HARNESS AND CONNECTOR

OK |

14.CHECK DOOR CONTROL RECEIVER (OUTPUT)

1. Reconnect the D10 receiver connector.

1. Measure the resistance of the connector.

   Standard voltage:

     Tester Connection | Condition | Specified Condition
     D10-2 (RDA) - Body ground | Transmitter switch ON → OFF (No key in ignition key cylinder, all doors closed) | Below 1 V → 6 to 7 V → Below 1 V

| OK |

REPLACE INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY (INTEGRATION RELAY)

NG |

15.REPLACE DOOR CONTROL TRANSMITTER MODULE

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

   OK:
     Doors can be locked and unlocked with transmitter.

| NG |

REPLACE DOOR CONTROL RECEIVER

OK |

END (DOOR CONTROL TRANSMITTER MODULE IS DEFECTIVE)
