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 passenger presence sensor.
|
2. |
Test for less than 30 Ω
between the ground circuit terminal 2 and ground. |
⇒ |
If greater than the specified range, test the
ground circuit for an open/high resistance. If the circuit tests
normal, replace the K36 inflatable restraint sensing and diagnostic
module. |
3. |
Ignition ON, test for
4.75-5.25 V between the signal circuit terminal 1 and
ground. |
⇒ |
If less than the specified range, test the signal
circuit for a short to ground or an open/high resistance. If the
circuit tests normal, replace the K36 inflatable restraint sensing
and diagnostic module. |
⇒ |
If greater than the specified range, test the
signal circuit for a short to voltage. If the circuit tests normal,
replace the K36 inflatable restraint sensing and diagnostic
module. |
4. |
If all circuits test normal,
replace the B60 passenger presence sensor. |
Repair Instructions
Perform the
Diagnostic Repair Verification after completing the repair.
