Diagnostic Trouble Code (DTC) Information SRS-B000511

Condition

The Supplemental restraint system module (SRS) checks the direct current (DC) in the circuit for the adaptive steering column.

The diagnostic trouble code (DTC) is stored if the control module detects that:

Direct current (DC) 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.
