INSPECTION
PROCEDURE
1. INSPECT NO. 1 COOLER THERMISTOR
(a) Measure the resistance according to the value(s) in the table below.
|
*a | Component without harness connected
(No. 1 Cooler Thermistor) |
*b | Sensing Portion |
|
*c | Resistance (kΩ) |
*d | Temperature (°C (°F)) |
|
*e | Allowable Range |
- | - |
Standard Resistance:
|
Tester Connection | Condition |
Specified Condition |
|
1 - 2 | -10°C (14°F) |
7.30 to 9.10 kΩ |
|
-5°C (23°F) | 5.65 to 6.95 kΩ |
|
0°C (32°F) | 4.40 to 5.35 kΩ |
|
5°C (41°F) | 3.40 to 4.15 kΩ |
|
10°C (50°F) | 2.70 to 3.25 kΩ |
|
15°C (59°F) | 2.14 to 2.58 kΩ |
|
20°C (68°F) | 1.71 to 2.05 kΩ |
|
25°C (77°F) | 1.38 to 1.64 kΩ |
|
30°C (86°F) | 1.11 to 1.32 kΩ |
If the resistance is not as specified, replace the No. 1 cooler thermistor.
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).
Installation
INSTALLATION
PROCEDURE
1. INSTALL NO. 1 COOLER THERMISTOR
(a) for 2GR-FKS:
| (1) Install the No. 1 cooler thermistor as shown in the illustration.
Installation Position: |
Part | Length | |
A | 50.0 mm (1.97 in.) | |
B | 61.1 mm (2.41 in.) |
NOTICE:
- Be sure to insert the No. 1 cooler thermistor only once because
reinserting it into the same position will not allow it to be firmly
secured.
- When reusing the No. 1 cooler evaporator sub-assembly, insert the No. 1
cooler thermistor one row next to the one that has been used previously
(X in the illustration).
- After inserting the No. 1 cooler thermistor, do not apply excessive force to the wire.
- Directly insert the No. 1 cooler thermistor until the edge of the
plastic case "a" comes into contact with the No. 1 cooler evaporator
sub-assembly "b".
|
 |
|
*a | Securing Part | |
*b | Sensor Part | | |
(b) for A25A-FXS:
| (1) Install the No. 1 cooler thermistor as shown in the illustration.
Installation Position: |
Part | Length | |
A | 50.0 mm (1.97 in.) | |
B | 87.9 mm (3.46 in.) | |
C | 188.3 mm (7.41 in.) |
NOTICE:
- Be sure to insert the No. 1 cooler thermistor only once because
reinserting it into the same position will not allow it to be firmly
secured.
- When reusing the No. 1 cooler evaporator sub-assembly, insert the No. 1
cooler thermistor one row next to the one that has been used previously
(X in the illustration).
- After inserting the No. 1 cooler thermistor, do not apply excessive force to the wire.
- Directly insert the No. 1 cooler thermistor until the edge of the
plastic case "a" comes into contact with the No. 1 cooler evaporator
sub-assembly "b".
