DTC B0082 Coupe
Circuit Description
When the ignition is turned ON, the SDM performs self-test to diagnose malfunctions
inside the module. The SDM provides input power to the SIS. When input power is first
detected, the SIS responds by performing internal diagnostics. Next the SIS sends
an ID message to the SDM. The SDM will consider this to be a valid ID if the response
time is less than 5 seconds after the SIS is powered up. The SIS will continually
communicate a status message to the SDM. The SDM can reset the SIS by removing and
applying power to it.
DTC Parameters

conditions must be met to set this DTC:
• | Ignition voltage is present at the SDM and continuous. |
• | The SDM has received an internal fault message from the right SIS. |
Action Taken
• | The air bag telltale will be ON. |
Diagnostic Aids
