Inspection Procedure

HAVE VEHICLE IN INITIAL CONDITION
1. Check the initial condition of the vehicle.
  1. No key in the ignition key cylinder.
  2. All doors closed (door open indicator off).
  3. All doors locked.
CHECK FUNCTION BY STANDARD OPERATION
1. Check that the LOCK/UNLOCK switch operation can be performed once more after the operation is repeated 3 times or more in the standard operation.
HINT:

The standard operation here means to press the transmitter switch for 1 second, facing the transmitter to the vehicle, in 1 m (3.28 ft) away from the driver's door.
1. OK: NORMAL
2. NG: GO TO NEXT STEP
CHECK TRANSMITTER BATTERY SIMPLY
1. When the transmitter battery is exchanged for a new or normal one, check that the LOCK/UNLOCK switch operation can be performed once more after the operation is repeated 3 times or more in the standard operation.
1. OK: REPLACE TRANSMITTER BATTERY
2. NG: GO TO NEXT STEP
ENTER INTO SELF-DIAGNOSTIC MODE
1. Enter into the self-diagnostic mode by an operation of the hand-held tester.
HINT:
- If the hand-held tester demands to finish the self-diagnostic mode, the system enters into the normal mode.
- During the self-diagnostic mode, do not carry out the LOCK/UNLOCK operation.
1. Check that the system has entered into the self-diagnostic mode by the wireless door lock buzzer sound.

1. NG: Go to step 9
2. OK: GO TO NEXT STEP
CHECK BY SELF-DIAGNOSTIC MODE
1. Inspect the output of the diagnosis when the door control transmitter switch has been kept pressed (The diagnosis output can be checked by the output of the wireless door lock buzzer sound).

HINT:
- In case of no diagnosis outputs (wireless door lock buzzer off), go to step NG-A.
- In case of discord of recognition code (wireless door lock buzzer on), go to step NG-B.
- In case of a reception of the normal wave of the LOCK/UNLOCK switch (wireless door lock buzzer sounds), go to step OK.
1. NG-B: Go to step 9
2. OK: Go to step 10
3. NG-A
CHECK BASIC OPERATION BY NEW TRANSMITTER
1. Enters into the self-diagnostic mode by an operation of the hand-held tester.
2. When a new or normal transmitter switch for the same type of vehicle is operated in the standard operation, check whether a discord of the recognition code is output.
HINT:
- Standard operation here means to press the transmitter switch for 1 second, facing the transmitter to the vehicle, in 1 m (3.28 ft) away from the driver's door.
1. OK: REPLACE TRANSMITTER SUB-ASSY MODULE SET DOOR CONTROL
2. NG: GO TO NEXT STEP

PERFORM ACTIVE TEST BY HAND-HELD TESTER (THEFT WARNING ECU)

Connect the hand-held tester to the DLC3.

Enter into the active test using the hand-held tester.

Standard:

ACTIVE TEST ITEM REFERENCE

Item	Operation
Overhead tuner	OUTPUT/STOP

During the active test, check that 5 V is input to terminal 5 (+5) of the inner rear view mirror (receiver) (119), using the oscilloscope.

Standard:

ACTIVE TEST CONDITIONS

Symbols (Terminal No.)	Condition	Specified Condition
+5(I19-5) <--> E1 (119-8)	During the active test	Hz output

NG: REPAIR OR REPLACE WIRE HARNESS (wireless receiver +5 - theft warning ECU RCO)
OK: GO TO NEXT STEP

CHECK WIRE HARNESS (THEFT WARNING ECU <--> WIRELESS DOOR CONTROL RECEIVER)
1. Disconnect the connectors of the inner rear view mirror and theft warning ECU.

2. Check the continuity between the inner rear view mirror connector (119) terminal 5 (+5) and the theft warning ECU connector (T7) terminal 15 (RCO).
  Standard: Continuity
1. OK: REPLACE TRANSMITTER SUB-ASSY MODULE SET DOOR CONTROL
2. NG: REPAIR OR REPLACE WIRE HARNESS (wireless receiver +5 - theft warning ECU RCO)

PERFORM ACTIVE TEST BY HAND-HELD TESTER (THEFT WARNING ECU (SWITCH CONDITION))

Connect the hand-held tester to the DLC3.
Enter into the active test using the hand-held tester.
1. Check that the wireless door lock buzzer sounds by the active test.
Standard:

ACTIVE TEST REFERENCE

Item	Motor
Wireless buzzer	ON/OFF

NG: GO TO FLOW CHART OR PROBLEM SYMPTOMS TABLE (See BUZZER CIRCUIT )
OK: REPLACE THEFT WARNING ECU ASSY

10 RE-REGISTER RECOGNITION CODE OF TRANSMITTER
1. Re-register the transmitter in the add mode.
1. OK: COMPLETED (RE-REGISTRATION RECOGNITION CODE IS NORMAL)
2. NG: REPLACE THEFT WARNING ECU ASSY
CHECK WIRE HARNESS (THEFT WARNING ECU <--> WIRELESS DOOR CONTROL RECEIVER)
1. Disconnect the connectors of the inner rear view mirror and theft warning ECU.

2. Check the continuity between the inner rear view mirror connector (119) terminal 9 (RSSI) and theft warning ECU connector (T7) terminal 30 (RSSI).
  Standard: Continuity
1. NG: REPAIR OR REPLACE WIRE HARNESS
2. OK: GO TO NEXT STEP
CHECK BASIC OPERATION BY NEW TRANSMITTER
1. Enters into the self-diagnostic mode by an operation of the hand-held tester.
2. When a new or normal transmitter switch for the same type of vehicle is operated in the standard operation, check whether a discord of the recognition code is output.
HINT:

Standard operation here means to press the transmitter switch for 1 second, facing the transmitter to the vehicle, in 1 m (3.28 ft) away from the driver's door.
1. NG: REPLACE TRANSMITTER SUB-ASSY MODULE SET DOOR CONTROL
2. OK: REPLACE INNER REAR VIEW MIRROR ASSY (DOOR CONTROL RECEIVER MALFUNCTION)
