PROCEDURE

1. INSPECT THERMISTOR ASSEMBLY

(a) Check the resistance.

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection

Condition

Specified Condition

A3-1 - A3-2

10°C (50°F)

3.00 to 3.73 kΩ

A3-1 - A3-2

15°C (59°F)

2.45 to 2.88 kΩ

A3-1 - A3-2

20°C (68°F)

1.95 to 2.30 kΩ

A3-1 - A3-2

25°C (77°F)

1.60 to 1.80 kΩ

A3-1 - A3-2

30°C (86°F)

1.28 to 1.47 kΩ

A3-1 - A3-2

35°C (95°F)

1.00 to 1.22 kΩ

A3-1 - A3-2

40°C (104°F)

0.80 to 1.00 kΩ

A3-1 - A3-2

45°C (113°F)

0.65 to 0.85 kΩ

A3-1 - A3-2

50°C (122°F)

0.50 to 0.70 kΩ

A3-1 - A3-2

55°C (131°F)

0.44 to 0.60 kΩ

A3-1 - A3-2

60°C (140°F)

0.36 to 0.50 kΩ

NOTICE:

  • Hold the sensor only by its connector. Touching the sensing portion may change the resistance value.
  • When measuring, the sensor temperature must be the same as the ambient temperature.

HINT:

As the temperature increases, the resistance decreases (see the graph).

If the result is not as specified, replace the thermistor assembly.

     Compressor Solenoid Circuit Short to Ground or Open (P06A014)

    DESCRIPTION In this circuit, the compressor with pulley assembly receives refrigerant compression demand signals from the air conditioning amplifier assembly. Based on this signal, the compressor with pulley assembly changes the amount of compressor output. DTC No. Detection Item DTC

     Stop Lamp Relay Actuator Stuck (C138071)

    DESCRIPTION Stop light switch and skid control ECU (brake actuator assembly) outputs a stop light signal. When the skid control ECU (brake actuator assembly) detects a circuit malfunction related to the stop light, it communicates to the forward recognition camera via CAN and outputs DTC C138
