Front Console Box (W/ Cool Box) -- Inspection |
1. INSPECT COOLER CONTROL SWITCH SUB-ASSEMBLY |
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection
| Switch Condition
| Specified Condition
|
1 - 2
| On
| Below 1 Ω
|
1 - 2
| Off
| 10 kΩ or higher
|
Apply battery voltage to the cooler control switch connector and check that the indicator illuminates.
- OK:
Measurement Condition
| Specified Condition
|
Battery positive (+) → Terminal 3 Battery negative (-) → Terminal 4
| indicator illuminates
|
If the result is not as specified, replace the cooler control switch.
2. INSPECT NO. 1 COOLER BLOWER MOTOR SUB-ASSEMBLY |
Apply battery voltage to the blower motor connector and check the operation of the blower motor.
- OK:
Measurement Condition
| Specified Condition
|
Battery positive (+) → Terminal 1 Battery negative (-) → Terminal 2
| Motor operates smoothly
|
If the result is not as specified, replace the blower motor.
3. INSPECT NO. 3 COOLER THERMISTOR |

- NOTICE:
- Even slightly touching the sensor may change the resistance value. Be sure to hold the connector of the sensor.
- 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 cooler thermistor.
