B1096 - Front Right Seat Heater Control Circuit Low






For a complete wiring diagram, refer to.

• When Monitored: Ignition ON, during the heated seat operation.

• Set Condition: This code is set immediately after the heated seat module detects the right seat heater B+ driver circuit shorted to ground.






Test Step 1 - Test For Intermittent Condition

• Turn the ignition ON.

• With the scan tool, clear all DTCs.

• Operate the heated seat switch in both positions several times.

• Adjust the seat forward and rearward as well as the seat back position while performing this test. This can help uncover an intermittent wiring problem with the heating element in the seat.

• With the scan tool, read DTCs.

Does the scan tool display B1096 - Front Right Seat Heater Control Circuit Low?

Yes

• Go to Test Step 2 => [ Test
Step 2 - Right Seat Heater B+ Driver Circuit Short to Ground ]

No

• The condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.

Test Step 2 - Right Seat Heater B+ Driver Circuit Short to Ground

• Turn the ignition OFF.

• Disconnect the driver seat C376 14 way assembly harness connector.

• Check connectors - Clean and repair as necessary.

• Measure the resistance of the right seat heater B+ driver circuit to the ground circuit at the driver seat C376 14 way assembly harness connector (body side).

Is the resistance below 1.0 ohm?

Yes

• Go to Test Step 3 => [ Test
Step 3 - Right Seat Heater B+ Driver Circuit Shorted to Ground ]

No

• Go to Test Step 4 => [ Test
Step 4 - Right Seat Heater B+ Circuit Shorted to Ground ]

Test Step 3 - Right Seat Heater B+ Driver Circuit Shorted to Ground

• Disconnect the passenger seat assembly 10 way harness connector.

• Check connectors - Clean and repair as necessary.

• Measure the resistance of the right seat heater B+ driver circuit to the ground circuit at the driver seat assembly 14 way harness connector (body side).

Is the resistance below 1.0 ohm?

Yes

• Repair the right seat heater B+ driver circuit for a short to ground.

• Perform Body Verification Test. Refer to => Non
- DTC Based Diagnostics. Body Interior

No

• Repair/replace the passenger seat pigtail/heating elements or seat harness as necessary for a short to ground.

• Perform Body Verification Test. Refer to => Non

Test Step 4 - Right Seat Heater B+ Circuit Shorted to Ground

• Ensure the seat assembly 14 way harness connector is still disconnected.

• Disconnect the heated seat module harness connector.

• Check connectors - Clean and repair as necessary.

• Measure the resistance between ground and the right seat heater B+ driver circuit at the HSM harness connector.

Is the resistance below 10k ohms?

Yes

• Repair the right seat heater B+ driver circuit for a short to ground.

• Perform Body Verification Test. Refer to => Non
