Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information SRS-B1A5587

Condition

The diagnostic trouble code (DTC) is stored if the control module detects that:
- No message regarding status of the collision signal.
- Incorrect value runs longer than 10 seconds.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
