Vehicle Speed Information Circuit
Body & comfort
A fault has been identified in the circuit providing vehicle speed data to the control systems. Manufacturer-specific definition; confirm applicability in the service information for the exact vehicle.
General code
Driver frontal airbag — stage 1 deployment control
Body & comfort · Supplemental restraint system (SRS)
B0001 identifies the stage 1 circuit of the driver's frontal airbag. The full subcode matters: excessive resistance, an electrical short and crossed circuits require different fault paths. It does not establish that the airbag itself needs replacement. Jaguar and GM examples below concern the vehicles listed in those bulletins; they are not universal repair instructions.
General code
Driver frontal airbag — stage 2 deployment control
Body & comfort · Supplemental restraint system (SRS)
B0002 identifies the stage 2 circuit of the driver's frontal airbag. The full subcode matters: excessive resistance, an electrical short and crossed circuits require different fault paths. It does not establish that the airbag itself needs replacement. Jaguar and GM examples below concern the vehicles listed in those bulletins; they are not universal repair instructions.
General code
Driver frontal airbag — stage 3 deployment control
Body & comfort · Supplemental restraint system (SRS)
B0003 concerns the driver's third frontal-airbag deployment circuit where that system is fitted. FCA documents the particular B0003-2B wiring-short case alongside steering-column communication errors. The base code alone does not distinguish that case from other manufacturer subfaults or justify replacing the airbag.
General code
Driver Knee Bolster Deployment Control
Body & comfort
Driver Knee Bolster Deployment Control. Basic catalogue definition; diagnostic details have not yet been reviewed.
General code
Collapsible steering column — deployment control
Body & comfort · Supplemental restraint system (SRS)
In the referenced restraint-system definition, B0005 concerns deployment control of a collapsible steering column. Its suffix can change the diagnosis completely. JLR documents B0005-56 as an incompatible RCM configuration after module replacement on specified North American Evoque L538 vehicles; that software case must not be generalised to every car.
