B0051
DTC B0051 - Diagnostic Chart:
CIRCUIT DESCRIPTION
Schematic:
The SDM contains a sensing device that converts vehicle velocity changes to an electrical signal. The electrical signal is generated by the SDM and compared to a value stored in memory. When the generated signals exceed the stored values, the SDM deploys the air bags and stores a DTC in its memory.
DTC PARAMETERS:
DTC B0051 sets when the SDM commands the inflator modules to deploy air bags. The following conditions must be met to set this DTC.
^ Ignition voltage is present at the SDM and continuous.
^ The SDM detects a frontal crash up to 30 degrees off vehicle centerline.
^ Crash was of sufficient force to warrant deployment of air bags.
ACTION TAKEN:
^ DTC B0051 will set.
^ The air bag telltale will be On.
^ DTC is latched in SDM memory.
DIAGNOSTIC AIDS:
^ Always start diagnosis of SIR DTCs with an inspection of vehicle, including its wiring and SIR components for visible damage.
IMPORTANT: DTC B0051 is a latched code and can not be cleared from SDM memory.
^ Always replace SDMs with DTC B0051 set, only after all collision repairs have been completed.
^ Always perform the "SIR Diagnostic System Check" procedure before using this chart. Diagnostic System Check
