Once calibration is completed, it is not necessary to perform the above procedures unless the magnetic
field strength is drastically changed.

CIRCUIT DESCRIPTION
When the brake pedal is depressed, the stop lamp switch assy sends a signal to the ECM. When the ECM
receives this signal, it cancels the cruise control.
Fail-safe function operates to enable normal driving even if there is a malfunction in the stop lamp signal
circuit.
The cancel condition occurs when positive battery voltage is applied to terminal STP.
When the brake is applied, battery positive voltage is normally applied to terminal STP of the ECM through the
STOP fuse and the stop lamp switch assy, and the ECM turns the cruise control off.

Fig. 5: Erasing Transmitter Codes In Garage Door Opener Clear Mode
Courtesy of TOYOTA MOTOR SALES, U.S.A., INC.
HINT:
All 3 registered transmitter codes will be erased. No option exists for only erasing one transmitter
code.
1. Press and hold the left and right switches of the garage door opener for 20 seconds. The LED
will begin to flash at a cycle of 5.6 Hz. Releasing the switches will end clear mode.
HINT:
If the switches are released within 10 seconds after the transmitter codes have been erased,
the garage door opener will enter registration mode.
If the switches are held for 10 seconds or more after the transmitter codes have been erased,
default codes will be set to the 3 switches of the garage door opener. Using these default
codes, operation of the garage door opener can be checked using a tester.
Timing chart of clear mode:

c. Low power mode:
1. If a garage door opener switch is held for 75 seconds or more, the garage door opener will
enter low power mode to economize on power consumption. When the garage door opener
has entered low power mode, the LED turns off.
1.INSPECT GARAGE DOOR OPENER
a. Press the switch and check that each red LED turns on. If one or more of the switches does not turn
on the LED, confirm normal operation of the fuse and wire harness, then replace the
garage door
