Hyundai Palisade (LX2): SRSCM / Front Impact Sensor (FIS)
Components and components location
1. Front impact sensor (FIS)
|
2. Front impact sensor (FIS)
|
Description and operation
The front impact sensor (FIS) is installed in the Front End Module (FEM). They
are remote sensors that detect acceleration due to a collision at its mounting
location. The primary purpose of the Front Impact Sensor (FIS) is to provide
an indication of a collision. The Front Impact Sensor (FIS) sends acceleration
data to the SRSCM.
Repair procedures
| • |
Do not turn the ignition switch ON and do not connect the battery
cable while replacing the front impact sensor.
|
|
| 1. |
Disconnect the battery negative cable, and wait for at least three minutes
before beginning work.
|
| 2. |
Disconnect the front impact sensor connector (B) and then remove the
front impact sensor (A) after loosening the mounting bolt.
|
| • |
Do not turn the ignition switch ON and do not connect the battery
cable while replacing the front impact sensor.
|
|
| 1. |
Install a new front impact sensor.
|
| 2. |
Tighten the front impact sensor mounting nut.
|
Tightening torque :
7.8 - 10.8 N.m (0.8 - 1.0 kgf.m, 5.7 - 7.2 lb-ft)
|
|
| 3. |
Connect the front impact sensor connector.
|
| 4. |
Install the radiator assembly.
|
| 5. |
Reconnect the battery negative cable.
