2005 HIGHLANDER REPAIR MANUAL (RM1144U)
ONLY WIRELESS CONTROL FUNCTION IS INOPERATIVE
CIRCUIT DESCRIPTION
The door control receiver receives a signal from transmitter and sends it to body ECU by line.
And the body ECU transmits the signal to the door lock assembly to control the door lock/unlock operation.
NOTICE:
The wireless door lock control system has a function with a large-scale multiplex communication
system. First of all, inspect the communication function depending on the ºHOW TO PROCEED WITH
TROUBLESHOOTINGº, and check that the communication system has no malfunction. Then finally
proceed with the troubleshooting. Also, in case that the wire harness between the body ECU and door
control receiver has been short-circuited, diagnostic code 42 will be output and the wireless control
will not function.
INSPECTION PROCEDURE
HINT:
The initial condition that the customizing function by the hand-held tester is not chosen is shown.
1. VEHICLE'S INITIAL CONDITION (CONDITION OF WIRELESS CONTROL POSSIBLE)
(a) No key in the ignition key cylinder.
(b) All doors closed (door open indicator off).
(c) All doors locked.
HINT:
The switch described in this text is a LOCK/ UNLOCK switch for transmitting, and it is built in the door control
transmitter.
1 CHECK TRANSMITTER BATTERY SIMPLY
(a) Check that the LED of the transmitter lights up 3 times when the switch has been pressed 3 times.
HINT:
If the LED does not light up when the switch has been pressed 3 times or more, it may be caused by the
dead battery. Replace the battery with a new or normal one, and then check that doors will be locked or un-
locked by the standard operation.
NOTICE:
Standard operation means to press and hold the transmitter switch for 1 second, facing the transmit-
ter to the vehicle, in 1 m (3.28 ft) away from the driver's door outside handle in the right direction.
