Notice: 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 DTC B1071 to set. When a scan tool clear codes command is issued and the malfunction is no longer present, DTC B1019 or B1025 and DTC 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.
