Side Impact Sensor(SIS) is located in both side of center pillar detects broad collision. When SIS delivers collision signal to SRSCM, SRSCM checks if safing sensor located in SRSCM detects collusion. and if both SIS and safing sensor detects collision simultaneously, SRSCM operates side air bag.
The SRSCM sets DTC B1415 if PSIS with wrong ID is detected.
Item | Detecting Condition | Possible Cause | |
DTC Strategy | ● When use incorrect Side Impact Sensor for the system. | ● Poor connection of connected part. ● Faulty PSIS. ● Faulty SRSCM. | |
Enable Conditions | ● Ignition "ON" | ||
Threshold Value | ● SIS sends the "Wrong ID" continously | ||
Diagnostic Time | Qualification | ● Less than 1 sec after SIS/FIS power on. | |
De-Qualification | ● On the Next ACU Ignition cycle. | ||
