DIAGNOSTIC TROUBLE CODE CHART
HINT:
If a malfunction code is displayed during the DTC check, check the circuit indicated by the DTC. For
details of each code, turn to the page for the respective ºDTC No.º in the DTC chart.
When U0121/94, U0123/62, U0124/95 or U0126/63 are output, inspect and repair the trouble areas
indicated by U0121/94, U0123/62, U0124/95 or U0126/63 first.

*1, *2:
Even after the trouble areas are repaired, the ABS warning light will not go off unless the following operations
are performed.
*1:
(1) Drive the vehicle at 12 mph (20 km/h) for 30 seconds or more and check that the ABS warning
light goes off.
(2) Clear the DTC (see page 05-765).
*2:
(1) Keep the vehicle in a stationary condition for 5 seconds or more and depress the brake pedal
lightly 2 or 3 times.
(2) Drive the vehicle at a vehicle speed of 31 mph (50 km/h). Then depress the brake pedal strongly
for about 3 seconds.
(3) Repeat the above operation 3 times or more and check that the ABS warning light goes off.
(4) Clear the DTC (see page 05-765).

B HOW TO USE THIS MANUAL
Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.
When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flows
through the rear lights warning light to TERMINAL 4 of the light failure sensor.
Stop Light Disconnection Warning
When the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the current
flowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects the
disconnection and the warning circuit of the light failure sensor is activated.
As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lights
warning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warning
circuit on and holds the warning light on until the ignition SW is turned off.

2005 HIGHLANDER from Nov. '04 Prod. (OM48570U)
In order to be effective, the SRS airbags must deploy with
tremendous speed. The rapid deployment of the SRS air-
bags makes the SRS airbags themselves potential sources
of serious injury if an occupant is too close to an airbag,
or if an object or some part of his or her body has been
placed between the occupant and the airbag at the time of
deployment. This is just one example of how the instruc-
tions in Section 1- 3 of this Owner 's Manual will help en-
sure proper use of the occupant restraint systems, and
increase the safety they can provide to you and your fami-
ly in the event of an accident.
Toyota recommends you to read the provisions in Section
1- 3 carefully and refer to them as needed during your time
of ownership of this vehicle.Event data recorder
Your vehicle has computers that monitor and control cer-
tain aspects of your vehicle. These computers assist in
driving and maintaining optimal vehicle performance. Be-
sides storing data useful for troubleshooting, there is a
system to record data in a crash or a near car crash
event. This is called an Event Data Recorder (EDR).
The SRS airbag sensor assembly contains the EDR. In a
crash or a near car crash event, this device records some
or all of the following information:
Engine speed
Whether the brake pedal was applied or not
Vehicle speed
To what extent the accelerator pedal was depressed
Position of the transmission selector lever
Whether the driver and front passenger wore the seat
belts or not
Driver 's seat position
Front passenger 's occupant classification
