Diagnostic Fault Information
Circuit/System Description
The inflatable restraint front end sensor utilizes a unidirectional 2-wire circuit. The front end sensor modulates current on the interface to send ID,
state of health, and deployment commands to the inflatable restraint sensing and diagnostic module (SDM). The SDM serves as a power source and
a ground for the front end sensor. When the ignition is turned ON and input power from the SDM is first detected, the front end sensor responds by
performing internal diagnostics and sending an ID to the SDM. The SDM considers the ID to be valid if the response time is less than 5 seconds.
The front end sensor continually communicates status messages to the SDM, which determines if a fault is present in the front end sensor circuit.
When a fault is detected, the SDM may reset the front end sensor up to 2 times by removing and reapplying power to it. If the fault is still present,
the SDM will set a DTC.
Conditions for Running the DTC
Ignition voltage is between 9-16 volts.
Conditions for Setting the DTC
Any of the following conditions exist for 2.5 seconds:
B0083 00, B0084 00, B0085 00, B0086 00, B0087 00, B0088 00
