Circuit/System Description |
The passenger 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 seat belt reminder sensor.
|
2. |
Test for less than 30 Ω between the ground circuit terminal 2 and ground.
|
3. |
If greater than the specified range, test the ground circuit for an open/high resistance. If the circuit tests normal replace the K36 SDM.
|
4. |
Ignition ON, test for 4.75-5.25 V between the signal circuit terminal 1 and ground.
|
5. |
If less than the specified range, test the signal circuit for short to ground or an open/high resistance. If the circuit tests normal replace the K36 SDM.
|
6. |
If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal replace the K36 SDM.
|
7. |
If all circuits test normal, replace the B60 seat belt reminder sensor.
|
Repair Instructions |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
