Diagnostic Fault Information
Circuit/System Description
The seat belt reminder sensor is within 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
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

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. Disconnect the harness connector at the B60 passenger presence sensor.
2. Test for less than 30 ohms between the low reference circuit terminal 2 and ground.
• If 30 ohms or greater
1. Ignition OFF, disconnect the X2 harness connector at the K36 SDM.
2. Test for less than 2 ohms in the low reference circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, replace the K36 SDM.
• If less than 30 ohms
3. Ignition ON.
4. Test for 4.75-5.25 V between the signal circuit terminal 1 and ground.
• If less than 4.75 V
1. Disconnect the X2 harness connector at the K36 SDM.
2. Test for infinite resistance between the signal circuit and ground.
• If less than infinite resistance, repair the short to ground on the circuit.
3. Test for less than 2 ohms in the signal circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, replace the K36 SDM.
• If greater than 5.25 V
1. Ignition OFF. Disconnect the X2 harness connector at the K36 SDM. Ignition ON.
2. 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.
• If between 4.75-5.25 V
5. Replace the B60 passenger presences sensor.
