PROCEDURE
1. |
CHECK FREQUENCY RECEIVING CONDITION |
(a) Check that the following conditions are not met:
(1) Facilities or devices that use similar radio frequencies are located in the vicinity of the vehicle.
HINT:
If the vehicle is located in an area such as the one described above, the tire pressure warning light may illuminate after blinking for 1 minute due to interfering radio frequencies.
(2) Devices using similar radio frequencies are used in the vehicle.
OK:
Facilities or devices that use similar radio frequencies are not located in the vicinity of the vehicle.
HINT:
Radio wave transmissions may be interrupted due to the surroundings, or devices installed by the user.

Mirror Heater does not Operate with Rear Defogger Switch
DESCRIPTION
When the mirror heater switch on the air conditioning control assembly is pressed,
the operation signal is sent to the air conditioning amplifier assembly. When the
air conditioning amplifier assembly receives the signal, it turns on a relay in
the air conditioning amplifier assem ...
