Side Impact Sensor(SIS) is located in both side of C 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 B1452 if there is short to power harness in RDSIS harness.
Item | Detecting Condition | Possible Cause |
DTC Strategy | ● Check current(PWM type) | ● Short to power in RDSIS harness. ● Faulty RDSIS. ● Faulty SRSCM. |
Enable Conditions | ● Ignition "ON" | |
Threshold Value | ● SIS/FIS no acceleration data, and line voltage >11V | |
Diagnostic Time | Qualification | ● More than 2.2 sec |
De-Qualification | ● More than 1 time |
