Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information SRS-B1D7512

Condition
The Supplemental restraint system module (SRS) checks the direct current (DC) voltage in the circuit for the switch, airbag, passenger front.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Direct current (DC) is too high.
- 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 to supply voltage in the cable.
- Short-circuit in connections.
- Contact resistance or oxidation in the terminals.
