Silverado 1500 2WD V8-4.8L VIN V (2006)
Malfunction Lamp / Indicator: Description and Operation
Passenger Air Bag On/Off Indicators
INFLATABLE RESTRAINT PASSENGER AIR BAG ON/OFF INDICATORS
The PASSENGER AIR BAG ON/OFF indicators located on the rearview mirror are used to notify the driver when the passenger presence system (PPS)
has enabled or disabled the instrument panel (I/P) inflator module. The PPS air bag indicators will also inform the driver of any PPS malfunctions. When
the ignition is turned on, the PPS module is supplied with ignition 1 voltage and commands both PASSENGER AIR BAG ON/OFF indicators ON for 5
seconds. The PPS module conducts tests on the PPS components and circuits while both ON/OFF indicators are ON. If no malfunctions are detected the
PPS module will turn the PASSENGER AIR BAG indicator ON or OFF depending on the status of the PPS. If a malfunction is detected, the PPS
module will store a DTC, default the PPS to the OFF state and communicate with the sensing and diagnostic module (SDM) that a DTC has been set.
When the SDM detects that the PPS has set a DTC, the SDM will set either DTC B0092 or B0098 and request the instrument panel cluster (IPC) to turn
the AIR BAG indicator located on the IPC ON. This is done to notify the driver of any PPS malfunctions. The presence of a SIR system malfunction
could result in non-deployment of the air bags. The AIR BAG indicator will remain ON until the malfunction has been repaired.
