Diagnostic Instructions
DTC Descriptor
DTC B1530: Discard Passenger Presence System 1
Circuit/System Description
When the ignition is turned ON, the inflatable restraint sensing and diagnostic module (SDM) performs tests to diagnose critical malfunctions within the passenger presence system (PPS) module. When the SDM has completed the power-up mode, the SDM will
establish communication with the PPS module. The SDM will increase a fault counter with each ignition cycle that a fault exists with the PPS module. The SDM will lock out the PPS module after a predetermined ignition cycle count maximum has been reached.
Conditions for Running the DTC
Ignition voltage is between 9-16 volts.
Conditions for Setting the DTC
• | The PPS module has a current fault. |
• | The PPS module fault counter in the SDM has reached 127 counts. |
Action Taken When the DTC Sets
• | The SDM disables the instrument panel (I/P) module deployment loop. |
• | The SDM requests the instrument panel cluster (IPC) to illuminate the AIR BAG indicator. |
• | The SDM will lock out the malfunctioning PPS module. |
Conditions for Clearing the DTC
• | The PPS module has been replaced. |
• | The SDM has been replaced. |
Diagnostic Aids
Important: DTC B0092 or DTC B0098 will set if the PPS has a malfunction, and has set any one of the following DTCs 023, 024, 063, 064, or 065. When DTC B0092 or DTC B0098 is present, it is important
to check the PPS for any current DTC. Refer to
Passenger Presence System Flash Code Procedures. If the PPS has any current DTC, address those DTC before performing this diagnostic procedure.
Any repair performed on the original PPS module will not clear DTC B1530.
