Traction Control Active Lamp – Circuit Short to Battery
Last updated: July 2026
C1104 is a manufacturer-specific chassis diagnostic trouble code. It is defined as "Traction Control Active Lamp – Circuit Short to Battery". It falls under the chassis systems area of the vehicle’s chassis system, and its exact meaning can vary between manufacturers.
The onboard diagnostic system sets C1104 when it detects a condition matching "traction control active lamp – circuit short to battery" in the chassis systems circuit or system. When the fault is confirmed, the module stores the code and, in most cases, turns on a warning light.
This code is generally considered serious. Continued driving may worsen the fault or affect safety and drivability. Have it diagnosed promptly.
C1104 means "Traction Control Active Lamp – Circuit Short to Battery". It is a manufacturer-specific chassis trouble code in the chassis systems area.
Because this code is often serious, it is best to limit driving and have the vehicle diagnosed as soon as possible. Continuing to drive may worsen the fault or affect safety.
There is no single fix. Start by confirming the code with a scan tool, then work through the likely causes and checks above — inspecting wiring, connectors and the relevant components before replacing any parts. On your specific make, confirm the diagnosis before repairs.
You can clear the code with an OBD-II scan tool, but if the underlying fault is still present it will usually return. Clearing without repair is only useful to confirm whether the fault is active.
