DESCRIPTION
SRSCM MALFUNCTION

The SRSCM shall also cyclically monitors the following:

  1. Functional readiness of the firing circuit activation transistors (driver and passenger side)

  1. Adequacy of deployment energy reserves (driver and passenger o side)

  1. Safing sensor integrity: detection of faulty closure (longer than 4 seconds)

  1. Plausibility of accelerometer signal

  1. 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).

The SRSCM must be replaced once the fault codes above mentioned are confirmed.
