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.

List of Troubles Trouble Description
AD converter or EEPROM trouble (in
case of RAM and ROM failure, the
microcontroller will reset and the warning
light will light up.)

Nonexecution of circular diagnostic test
(Repeated algorithm calculation)
Close for 2 or more than 2 seconds
Safety sensor is open circuit when
calculating the trouble with algorithm
All the ignition currents are normal
when the current SRS is deployed
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).
