INSPECTION
PROCEDURE
1. INSPECT COOLER THERMISTOR (AMBIENT TEMPERATURE SENSOR)
(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

Specified Condition |
---|---|---|
1 - 2 |
10°C (50°F) |
3.00 to 3.73 kΩ |
15°C (59°F) |
2.45 to 2.88 kΩ |
|
20°C (68°F) |
1.95 to 2.30 kΩ |
|
25°C (77°F) |
1.60 to 1.80 kΩ |
|
30°C (86°F) |
1.28 to 1.47 kΩ |
|
35°C (95°F) |
1.00 to 1.22 kΩ |
|
40°C (104°F) |
0.80 to 1.00 kΩ |
|
45°C (113°F) |
0.65 to 0.85 kΩ |
|
50°C (122°F) |
0.50 to 0.70 kΩ |
|
55°C (131°F) |
0.44 to 0.60 kΩ |
|
60°C (140°F) |
0.36 to 0.50 kΩ |
HINT:
As the temperature increases, the resistance decreases (refer to the graph).
NOTICE:
If the result is not as specified, replace the cooler thermistor (ambient temperature sensor).

Open Circuit in IG1/IG2 Power Source Circuit (C1242)
DESCRIPTION
If there is a problem with the master cylinder solenoid (skid control ECU) power
supply circuit, the skid control ECU stores DTCs and prohibits operation under the
fail-safe function.
If the voltage supplied to the IG2 terminal is within the ...
