Supplemental restraint system monitoring and diagnostic self-testing on the 2023 Cadillac CT5 are regulated by Restraint Control Module (RCM) logic, instrument cluster warning lamps, and CAN-bus sensor networks.
How to Fix It:
-
Turn Ignition On: Switch the ignition to the on position without starting the engine to initiate the automatic system self-test.
-
Observe SRS Indicator: Watch the red airbag warning icon on the instrument panel flash briefly and then turn off, confirming normal readiness.
-
Service Active Faults: Schedule professional diagnostics if the airbag light stays illuminated or flashes continuously, indicating a stored fault code.
