DTC 14

SRSCM MALFUNCTION





- The SRSCM (SRS Control Module) shall also cyclically monitor the following:
a. Functional readiness of the firing circuit activation transistors (driver and passenger side)
b. Adequacy of deployment energy reserves (driver and passenger-side)
c. Safing sensor integrity: detection of faulty closure (longer than 4 seconds)
d. Plausibility of accelerometer signal
e. Operation of SRSCM components (A/D-converter, etc.)

The timely completion of all tests is monitored by a separate hardware watchdog. During normal operation, the watchdog is triggered periodically by the SRSCM; if the SRSCM fails to trigger the watchdog, the watchdog will reset the SRSCM and activate the SRI (Service Reminder Indicator).
