B2182

B2182-HEATED SEAT MODULE POWER SUPPLY HIGH





For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams.

- When Monitored:
With ignition on.

- Set Condition:
If the Heated Seat Module detects voltage over 16.0 volts on the on the (F937) Fused Ignition Switch Output (Run) circuit.





1. CHECK FOR CHARGING SYSTEM DIAGNOSTIC TROUBLE CODES (DTCs)
1. Turn the ignition on.
2. With the scan tool, read Engine Control Module (ECM) or Powertrain Control Module (PCM) DTCs.

Are there any Charging System DTCs set in the ECM or PCM?

Yes

- Testing and Inspection for Charging System diagnostic procedures.

No

- Go To 2

2. VERIFY DTC B2182-HEATED SEAT MODULE POWER SUPPLY HIGH IS ACTIVE
1. With the scan tool, record and erase DTCs.
2. Turn the ignition off.
3. Start the engine and let it run for one minute.
4. With the scan tool, read DTCs.

Is DTC B2182-HEATED SEAT MODULE POWER SUPPLY HIGH active?

Yes

- Go To 3

No

- The conditions that caused this code to set are not present at this time. Verify seat harness is routed correctly to the HSM. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform BODY VERIFICATION TEST. Body Verification Test.

3. CHECK (F937) FUSED IGNITION SWITCH OUTPUT (RUN) CIRCUIT VOLTAGE




1. Turn the ignition off.
2. Disconnect the HSM connector.

NOTE: Check connectors. Clean and repair as necessary.

3. Start the engine and let idle.
4. Measure the voltage of the (F937) Fused Ignition Switch Output (Run) circuit between the HSM connector and ground and compare it to the voltage at the vehicle battery.

Is the voltage measured at the HSM connector the same as the voltage measured at the battery?

Yes

- Replace the Heated Seat Module (HSM).
- Perform BODY VERIFICATION TEST. Body Verification Test.

No

- Repair the (F937) Fused Ignition Switch Output (Run) circuit for the cause of the high voltage condition at the HSM.
- Perform BODY VERIFICATION TEST. Body Verification Test.
