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 left front seat heater has a wiring issue where it's creating a path to ground, causing the system to trigger a fault. This usually means that there's damaged wiring or a malfunctioning heater element.
What the computer is actually seeing
The airbag or body control module detects low resistance in the seat heater circuit, indicating a fault with the circuit possibly being shorted to ground.
What a healthy reading looks like
Resistance between the heater terminals should typically be around 5-20 ohms. Voltage at the connector should be around 12V when the heater is activated.
