COMPONENT LOCATION |
GENERAL DESCRIPTION |
Front Impact Sensor(FIS)located at both sides of the front of engine room detects head-on collision.
When FIS delivers collision signal to SRSCM, SRSCM checks if safing sensor located in SRSCM detects collusion.
and if both FIS and safing sensor detects collision simultaneously, SRSCM operates front air bag.
DTC DESCRIPTION |
The SRSCM sets DTC B1330 if DFIS with wrong ID is detected

DIAGNOSTIC CIRCUIT DIAGRAM |
TERMINAL AND CONNECTOR INSPECTION |
1. | Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage. |
2. | Thoroughly check shorting connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. |
3. | Has a problem been found?
|
COMPONENT INSPECTION |
1. | Ignition “ON” & Engine “OFF” and Using a scan tool, clear the DTC. |
2. | Ignition “OFF”. |
3. | Disconnect the battery (-) terminal cable from the battery, and wait at least one minutes. |
4. | Disconnect DFIS connector . |
5. | Substitute the DFIS and check for proper operation. |
6. | Is DTC present problem ?
