Description and operation
Mounted inside the Manifold Absolute Pressure Sensor, Intake Air Temperature
Sensor (IATS) detects the intake air temperature.
To precisely calculate the amount of air, correction of the air temperature is
required as the air density varies with the temperature. So the ECM uses not only
MAPS signal but also IATS signal. This sensor has a Negative Temperature Coefficient
(NTC) thermistor with resistance in reverse proportion to the temperature.

Repair procedures
| 1. |
Switch "OFF" the ignition.
|
| 2. |
Disconnect the IATS connector.
|
| 3. |
Measure resistance between the IATS terminals 3 and 4.
|
| 4. |
Check that the resistance is within the specification.

|
| • |
Install the component to the specified torques.
|
| • |
Note that internal damage may occur when the component is dropped.
If the component has been dropped, inspect before installing.
|
| • |
Insert the sensor in the installation hole and be careful not
to damage it.
|
|
| 1. |
Install in the reverse order of removal.

Description and operation
Description
The primary purpose of the SRSCM (Supplemental Restraints System Control Module)
is to discriminate between an event that warrants restraint system deployment and
an event that does not. The SRSCM must decide whether to deploy the restraint system
or not. After determining that pretensioners and/or airbag deployment is required,
the SRSCM must supply sufficient power to the pretensioners and airbag igniters
to initiate deployment.

General Safety Information
and Caution
Be careful when driving the vehicle using the smart cruise control system as
follows.
•
The smart cruise control system may be restricted to detect distance
to the vehicle ahead due to road and traffic conditions.
