An external watchdog can check the operation situation of the microcontroller. The failure of the microcontroller
can trigger the watchdog, which in turn can reset the microcontroller and turn on the warning light.

calculating the trouble with algorithm
13 Ignition current

All the ignition currents are normal
when the current SRS is deployed
14 No confirmation of side SRS ignition

Even if the SRS ECU (HAE2.5) have
received for 5 times the ignition information
during the HSIS ignition cycle, the side SRS
airbag ignition can not be verified by SRS
ECU (HAE2.5).
