INSTALLATION
Temporarily install the new parts and measure each part of the new parts in accordance with the body dimension
diagram. (See the body dimension diagram)
Inspect the fitting of the related parts around the new parts before welding. This affects the appearance of the
finish.
After welding, apply the polyurethane foam to the corresponding parts.
After welding, apply body sealer and under-coating to the corresponding parts.
After applying the top coat layer, apply anti-rust agent to the inside of the necked section structural weld spots.

- DIAGNOSTICSWIRELESS DOOR LOCK CONTROL SYSTEM
2160 Author: Date:
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.
NG REPLACE TRANSMITTER (LITHIUM) BATTERY
OK
2 CONFIRM ROOM LAMP ON
(a) Check that the room lamp comes on.
HINT:
When the lamp does not come on, proceed with the self-diagnostic mode after repairing the room lamp.

3 ENTER INTO SELF-DIAGNOSTIC MODE
(a) Enter into the self-diagnostic mode by operating the ignition switch lock cylinder.
(1) Insert the key into the ignition switch lock cylinder under the vehicle's initial condition, and then
operate the ignition switch assembly OFF "ON "OFF once within 5 seconds after the key is
pulled out.
(2) Within 30 seconds after the ignition switch assembly is turned OFF, operate the ignition switch
assembly OFF "ON "OFF 9 times.
NOTICE:
The mode returns to the normal mode if even one of the above conditions has not been met.
HINT:
The operation of the ignition switch assembly OFF "ON will finish the self-diagnostic mode.
Do not carry out the lock/unlock operations during the self-diagnostic mode.
(b) Check that the system has entered into the self-diagnostic mode by blinks of the room lamp.
