Seat Belt Reminder Sensor Short to Battery

DTC B0082 02
Seat Belt Reminder Sensor Short to Ground

DTC B0082 04
Seat Belt Reminder Sensor Open Circuit

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 whether or not the seat is occupied.

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.
2. Disconnect the harness connector at the B60 seat belt reminder sensor.
3. Test for less than 30 ohm between the ground circuit terminal 2 and ground.
3.1. Ignition OFF, disconnect the harness connector at the K36 SDM.
3.2. Test for less than 2 ohm in the passenger air bag disable switch ground circuit end to end.

4. Ignition ON, test for 4.75-5.25 V between the signal circuit terminal 1 and ground.
4.1. Disconnect the harness connector at the K36 SDM.
4.2. Test for infinite resistance between the signal circuit and ground.
4.3. Test for less than 2 ohm in the signal circuit end to end.
4.1. Ignition OFF.
4.2. Disconnect the harness connector at the K36 SDM.
4.3. Ignition ON.
4.4. Test for less than 1 V between the signal circuit and ground.

5. Replace the B60 seat belt reminder sensor.

Repair Instructions
