Hummer H3. Manual — part 584

A history DTC will clear once 255 malfunction-free ignition cycles have occurred.

Diagnostic Aids

The following can cause an intermittent condition:

A short between the SPS signal and low reference circuits

High or low resistance in the SPS signal and low reference circuits

Inspect the SPS signal and return circuits carefully for cutting and/or chafing.

Circuit/System Testing

1. With the ignition OFF, disconnect the SPS connector.

If DTC B0083 is present, disconnect the right SPS located on the RF outboard seat
track.

If DTC B0084 is present, disconnect the left SPS located on the LF outboard seat
track.

2. Test and inspect the component signal and ground circuits for damage or corrosion.

3. Replace the defective SPS.

If DTC B0083 is present, replace the right SPS located on the RF outboard seat track.

If DTC B0084 is present, replace the left SPS located on the LF outboard seat track.

4. With the ignition ON, use a scan tool to observe the SIR DTC display. Verify DTC B0083

and/or B0084 is cleared.

5. If DTC does not clear remove the inflatable restraint SDM connector. Inspect the SDM

connector for damage or corrosion that may cause a malfunction in the SPS high and/or low
circuits.

If damage or corrosion is found make the appropriate repair.

6. Test the high and low circuits between the SDM and SPS for a short to voltage, short to

ground or open/low resistance.

If circuits test good then replace the SDM.

DTC Descriptor

DTC B0092

Passenger Presence System Performance

Circuit/System Description

When the ignition is turned ON, the inflatable restraint sensing and diagnostic module (SDM)
performs tests to diagnose critical malfunctions within itself. When the SDM has completed the
power-up mode, the SDM will establish communication with the passenger presence system
(PPS). The PPS will respond by commanding both the PASSENGER AIR BAG ON/OFF
indicators ON for 5 seconds. The SDM will transmit a request message to the PPS to receive the
PPS verification ID. The PPS will transmit the verification ID to the SDM and the SDM will
compare the ID received to data stored in memory. The SDM will also set DTC B0092 to notify
the driver that the PPS has a current malfunction present. When the SDM detects that the PPS has

2007 RESTRAINTS Supplemental Inflatable Restraints - H3

set any one of the following DTCs 023, 024, 063, 064 or 065, the SDM will disable the
instrument panel (I/P) module deployment loop, set DTC B0092 and command the AIR BAG
indicator ON.

Conditions for Running the DTC

Ignition 1 voltage is within the normal operating voltage range.

Conditions for Setting the DTC

The PPS has a current fault.

The SDM has not received the correct verification ID from the PPS.

Action Taken When the DTC Sets

The SDM disables the I/P module deployment loop.

The SDM commands the AIR BAG indicator ON via class 2 serial data.

Conditions for Clearing the DTC

The condition responsible for setting the DTC no longer exists.

The scan tool CLEAR DTC command has been issued.

A history DTC will clear once 255 malfunction-free ignition cycles have occurred.

Diagnostic Aids

DTC B0092 is an indication that the SDM has received an incorrect PPS verification ID or has
lost communication with the PPS. The SDM will continue to request the verification ID from the
PPS for 5 seconds. If the SDM does not receive the correct verification ID from the PPS within 5
seconds, the SDM will set the DTC as current, illuminate the AIR BAG indicator and disable the
I/P module deployment loop.

IMPORTANT: DTC B0092 will also set, if the PPS has a current malfunction and

has set any one of the following DTCs 023, 024, 064 or 065. The
SDM will set DTC B0092 as current and command the AIR BAG
indictor ON. This is done to notify the driver of any PPS
malfunctions. When DTC B0092 is present, it is important to
check the PPS for any current DTC. Refer to Passenger Presence
System Flash Code Procedures. Any current PPS DTC must be
diagnosed before performing this diagnostic procedure.

Circuit/System Testing

1. With the scan tool, check for PPS DTC. Refer to Passenger Presence System Flash Code

Procedures.

Diagnose all PPS DTC. Refer to Diagnostic Trouble Code (DTC) List - Vehicle .

2. Inspect the PPS and passenger seat inline connector for corrosion or damage.

If any of the above conditions are found, make the appropriate repair.

3. Test the voltage circuits for the PPS for a short to ground or open/high resistance.

If any of the above conditions are found, make the appropriate repair.

4. Reconnect all components, with ignition ON use the scan tool to clear DTC. Recheck for

DTC. When all PPS faults have been repaired, rezero the PPS.

5. Verify that DTC B0092 does not set as a current DTC. If DTC B0092 does set as a current

DTC, replace and rezero the PPS.

After replacement and the rezeroing of the PPS are completed, perform the repair
verification.

Repair Procedures

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

IMPORTANT: If the PPS has any current or history DTC stored, you must

address the PPS DTC before continuing with this diagnostic
procedure.
