Only Wireless Control Function Is Inoperative
DOOR LOCK: WIRELESS DOOR LOCK CONTROL SYSTEM (w/o Smart Key System): Only Wireless Control Function is Inoperative
Only Wireless Control Function is Inoperative
DESCRIPTION
The door control receiver receives signals from the transmitter and sends these signals to the main body ECU. The main body ECU then controls all doors by sending lock/unlock signals to each door lock.

INSPECTION PROCEDURE
PROCEDURE
1. CHECK WIRELESS DOOR LOCK CONTROL FUNCTION
(a) Check the wireless door lock control functions Operation Check.
OK:
Each function of wireless door lock control system operates normally using transmitter switches.
OK -- NORMAL
NG -- Continue to next step.
2. CHECK THAT TRANSMITTER LED LIGHT UP
(a) 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 -- CHECK TRANSMITTER BATTERY (OPERATION)
OK -- Continue to next step.
3. CHECK WIRELESS DOOR LOCK CONTROL FUNCTION (STANDARD OPERATION)
(a) Check standard UNLOCK/LOCK switch operation.
NOTE: Standardized test procedures:
Press the transmitter switch for 1 second, directing the transmitter to the driver side door outside handle from a distance of 1 m (3.28 ft.). The transmitter should be pointed directly at the handle, i.e. a 90° angle to vehicle body.
OK:
Doors can be locked and unlocked with transmitter.
NG -- SWITCH TO SELF-DIAGNOSTIC MODE
OK -- REPLACE DOOR CONTROL TRANSMITTER
4. CHECK TRANSMITTER BATTERY (OPERATION)
(a) Temporarily replace the transmitter battery with a new or normally functioning one.
(b) 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 switch.
NG -- REPLACE DOOR CONTROL TRANSMITTER
OK -- END (TRANSMITTER BATTERY IS DEFECTIVE)
5. SWITCH TO SELF-DIAGNOSTIC MODE
(a) Switch to self diagnostic mode using the Techstream.
(1) Connect the Techstream (with CAN VIM) to the DLC3.
(2) Turn the power switch ON (IG) and push the Techstream main switch ON.
HINT: Please refer to the Techstream operator's manual for further details.
(b) Switch to self diagnostic mode by operating the key.
(1) Put the vehicle under the vehicle's initial condition Operation Check, insert the key into the key slot and remove it.
(2) Within 5 seconds of removing the key (above step), insert the key into the key slot. Then turn the power switch ON (IG) and OFF.
(3) Within 30 seconds of switching the power switch OFF (step above), perform the following 9 times:.
Turn the power switch ON (IG) and OFF*
NOTE: If the change to self diagnostic mode has failed, the system will return to normal mode.
HINT:
- Turning the power switch ON (IG) after step * has been completed will end self-diagnostic mode.
- Do not lock or unlock doors during the self-diagnostic mode.
(c) Check that the system has switched to self diagnostic mode by checking the flashes of the room light (dome light or key slot light). Compare the flash patterns of the room light to the timing chart on the illustration.
OK:
Flash pattern of room light should be the same as that shown in timing chart on illustration.
NG -- CONFIRM INPUT METHOD OF SELF-DIAGNOSTIC MODE
OK -- Continue to next step.
6. CHECK BY SELF-DIAGNOSTIC MODE
(a) Inspect the diagnosis outputs when the door control transmitter switch is held down. The diagnosis outputs can be checked by flash patterns of the room light.
Result:
C -- CHECK DOOR CONTROL RECEIVER (RESPONSE)
B -- REPLACE DRIVER SIDE JUNCTION BLOCK ASSEMBLY (MAIN BODY ECU)
A -- Continue to next step.
7. REGISTER RECOGNITION CODE
(a) Check that the system can switch to rewrite mode or add mode and recognition code can be registered.
OK:
System can switch to rewrite mode or add mode and recognition code can be registered.
NG -- CHECK DOOR CONTROL TRANSMITTER (OPERATION)
OK -- END
8. CHECK DOOR CONTROL RECEIVER (RESPONSE)
(a) Temporarily replace the door control receiver with a new or normally functioning one.
(b) Check that an unmatching recognition code is output when the door lock control transmitter switch is held down.
OK:
Unmatching recognition code is output.
NG -- CHECK WIRE HARNESS (DOOR CONTROL RECEIVER - BATTERY AND BODY GROUND)
OK -- REPLACE DOOR CONTROL TRANSMITTER
9. CONFIRM INPUT METHOD OF SELF-DIAGNOSTIC MODE
Result:
B -- SWITCH TO SELF-DIAGNOSTIC MODE
A -- Continue to next step.
10. INSPECT KEY SLOT
(a) Measure the resistance of the halfway switch.
Standard resistance:
NG -- REPLACE KEY SLOT
OK -- Continue to next step.
11. CHECK WIRE HARNESS (KEY SLOT - DRIVER SIDE JUNCTION BLOCK AND BODY GROUND)
(a) Disconnect the K2 slot connector.
(b) Disconnect the 1E junction block connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
12. CHECK WIRE HARNESS (DOOR CONTROL RECEIVER - BATTERY AND BODY GROUND)
(a) Disconnect the D4 receiver connector.
(b) Measure the resistance and voltage of the wire harness side connector.
Standard resistance:
Standard voltage:
NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
13. CHECK WIRE HARNESS (DOOR CONTROL RECEIVER - MAIN BODY ECU)
(a) Disconnect the D4 receiver connector.
(b) Disconnect the B7 ECU connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
14. CHECK DOOR CONTROL RECEIVER (OUTPUT)
(a) Reconnect the D4 receiver connector.
(b) Measure the voltage of the connector.
Standard voltage:
OK -- REPLACE DRIVER SIDE JUNCTION BLOCK ASSEMBLY (MAIN BODY ECU)
NG -- Continue to next step.
15. CHECK DOOR CONTROL TRANSMITTER (OPERATION)
(a) Temporarily replace the door control receiver with a new or normally functioning one.
(b) 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 IS DEFECTIVE)
