Seat Heat Control Circuit Short to Ground
A short circuit is detected in the seat heat control circuit.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The seat heating system is malfunctioning because there’s a wiring issue shorting out the circuit, likely due to frayed wires touching metal parts.
What the computer is actually seeing
The body control module (BCM) monitors the seat heater circuit. It expects a specific resistance level. A short can lead the BCM to see 0 ohms instead of 5 ohms, indicating a failure point.
What a healthy reading looks like
Resistance in the seat heater circuit should typically be between 5 - 15 ohms when not shorted. When shorted, it will read close to 0 ohms.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the seat heater harness for visible damage or frayed wires. Look for wires that may be touching metal. Decision: If damage is found, repair wiring. If not, continue.
- 22. Check the connectors for corrosion or poor connection. Use contact cleaner if necessary. Decision: If corrosion is found, clean or replace connectors. If connections are good, continue.
- 33. Measure resistance of the seat heater element with a multimeter. Disconnect the harness and check between terminals. Decision: If resistance is within 5-15 ohms, element is likely good. If < 5 ohms, replace seat heater element.
Common causes
- Frayed wiring in seat heater harness
- Corroded connectors
- Faulty seat heater element
