When disconnecting the cable, some systems need to be initialized after the cable
is reconnected (See page ).
2. REMOVE NO. 2 SWITCH HOLE BASE
3. REMOVE LOWER INSTRUMENT PANEL FINISH PANEL ASSEMBLY
4. REMOVE INSTRUMENT CLUSTER FINISH PANEL SUB-ASSEMBLY
5. REMOVE COMBINATION METER ASSEMBLY
6. REMOVE COOLER THERMISTOR (ROOM TEMPERATURE SENSOR)
(a) Disconnect the connector and hose.
(b) Detach the 2 claws and remove the cooler thermistor.

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 |

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 (room temperature sensor).

Steering Angle Sensor Zero Point Malfunction (C1290)
DESCRIPTION
The skid control ECU acquires steering angle sensor zero point every time the
ignition switch is turned to ON and the vehicle is driven at 40 km/h (25 mph) or
more for approximately 10 seconds. The ECU also stores the previous zero point.
