Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information SRS-B00821A

Condition
The Supplemental restraint system module (SRS) checks the resistance for the adaptive seat belt force limiter, passenger front.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The resistance is too low.
- Incorrect value runs longer than 2.5 seconds.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition position II and III.

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.





Substitute value
- None.

Possible source
- Short-circuit in wiring.
- Short-circuit in connections.
- Short-circuit in adaptive seat belt force limiter, passenger front (resistance too low in igniter).

Fault symptom[s]
- SRS warning light on
- SRS warning message displayed
