Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information FSM-U045268

Condition

Note! This diagnostic trouble code (DTC) status is an event controlled diagnostic trouble code (DTC). An event controlled diagnostic trouble code (DTC) does not mean that there is a fault in the control module when it is active, but is designed as information.

The control module is continuously supplied with necessary information from Supplemental restraint system module (SRS) via CAN-communication. The control module checks the quality of the information coming from the Supplemental restraint system module (SRS).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Transmitting control module indicates a lower quality level of the information than what Forward Sensing Module (FSM) accepts.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Engine running.
- Control module supplied with power.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.
