INSPECTION
PROCEDURE
1. INSPECT SEAT HEATER SWITCH LH
(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection |
Switch Condition |
Specified Condition |
---|---|---|
3 (SW) - 7 (RV) |
Switch off |
2.7 to 4.1 kΩ |
Switch on (Min.) |
||
Switch on (Max.) |
0.28 to 0.42 kΩ |
HINT:
As the dial is being turned, the resistance changes gradually.
If the result is not as specified, replace the seat heater switch.

Ambient Temperature Sensor Circuit (B1412)
DESCRIPTION
The cooler thermistor (ambient temperature sensor) is installed in the front
part of the cooler condenser assembly. This sensor is connected to the air conditioning
amplifier assembly and detects fluctuations in the ambient temperature. The se ...
