DTC B1071 Internal SDM Failure:

CIRCUIT DESCRIPTION
DTC B1071 is an indication of a potential internal inflatable restraint Sensing and Diagnostic Module (SDM) malfunction. DTC B1071 is set by the detection of any condition in the table below.




CONDITIONS FOR SETTING THE DTC

ACTION TAKEN WHEN THE DTC SETS
^ The SDM sets a diagnostic trouble code.
^ The SDM attempts to turn on the AIR BAG warning lamp.

CONDITIONS FOR CLEARING THE DTC
^ Current DTC
The malfunction has not been detected for 500 milliseconds.
^ History DTC
- You issue a scan tool CLEAR CODES command.
- 250 ignition cycles have occurred without a malfunction.

DIAGNOSTIC AIDS
DTC B1071 indicates a fault within the SDM. Replace the SDM if DIG B1071 indicates a fault within the SDM. Replace the SDM if DTC B1071 sets, current or history.

NOTE: When DTC B1019 or B1025 is set, it is necessary to replace the inflatable restraint Sensing and Diagnostic Module (SDM). Setting DTC B1019 or B1025 also causes DIG B1071 to set. When a scan tool clear codes command is issued and the malfunction is no longer present, DIG B1019 or B1025 and DIG B1071 will remain current. Ensure that the short to ground condition is repaired prior to installing a replacement SDM in order to avoid damaging the SDM.
