Diagnostic Fault Information
Circuit/System Description
The seat belt reminder sensor is in the passenger seat cushion and provides
an input to the inflatable restraint
sensing and diagnostic module (SDM). The SDM supplies a low reference circuit
and a seat belt reminder sensor
signal circuit to determine seated or unseated condition of passenger seat.
Conditions for Running the DTC
Ignition voltage is between 9 - 16 V.
Conditions for Setting the DTC
B0082 01
The SDM detects a short to voltage in the seat belt reminder sensor signal
circuit.
B0082 02
The SDM detects a short to ground in the seat belt reminder sensor signal
circuit
B0082 04
The SDM detects an open/high resistance in the seat belt reminder sensor
signal circuit or the seat belt reminder
sensor ground circuit
B0082 05
The inflatable restraint sensing and diagnostic module detects short to
voltage or an open/high resistance in the
seat belt reminder sensor signal circuit or an open/high resistance in the seat
belt reminder sensor ground circuit.
Action Taken When the DTC Sets
The SIR System is disabled and no deployments are allowed.
Conditions for Clearing the DTC
- The DTC will be current for as long as the fault is present
- When the fault is no longer present, the DTC will be a history DTC
- A history DTC will clear after 50 ignition cycles.

Scan Tool Reference
Refer to Control Module References for scan tool information.
Circuit/System Verification
1. Ignition ON, with the passenger seat unoccupied, verify the scan tool
Passenger Seat Occupancy Status
parameter is Empty Seat.
2. With the passenger seat occupied, verify the scan tool Passenger Seat
Occupancy Status parameter is
Occupied.
Circuit/System Testing
1. Ignition OFF.
2. Disconnect the harness connector at the B60 seat belt reminder sensor.
3. Test for less than 30 Ω between the ground circuit terminal 2 and ground.
- Ignition OFF, disconnect the harness connector at the K36 SDM.
- Test for less than 2 Ω in the passenger air bag disable switch ground
circuit end to end.
- If 2 Ω or greater, replace the coil or repair the open/high
resistance in the circuit.
- If less than 2 Ω, replace the K36 SDM.
- Go to next step: If less than 30 Ω
4. Ignition ON, test for 4.75 - 5.25 V between the signal circuit terminal 1
and ground.
- Disconnect the harness connector at the K36 SDM.
- Test for infinite resistance between the signal circuit and ground.
- If less than infinite resistance, repair the short to ground on the
circuit.
- Test for less than 2 Ω in the signal circuit end to end.
- If 2 Ω or greater, repair the open/high resistance in the circuit.
- If less than 2 Ω, replace the K36 SDM.
- Ignition OFF.
- Disconnect the harness connector at the K36 SDM.
- Ignition ON.
- Test for less than 1 V between the signal circuit and ground.
- If 1 V or greater, repair the short to voltage on the circuit.
- If less than 1 V, replace the K36 SDM.
- Go to next step: If between 4.75 - 5.25V
5. Replace the B60 seat belt reminder sensor.
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic
procedure.
- Refer to Control Module References for SDM replacement, setup, and
programming.
