About C1104

C1104 is a manufacturer-specific chassis diagnostic trouble code. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C1104 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

Scanning & clearing: Chassis (C) codes are stored in the ABS, traction control, or stability-control modules. An enhanced or OEM-level scan tool is usually required to read and clear them.

C1104 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

DTC C1104 is a chassis code set by the traction control or ABS module when it detects a short to battery voltage in the traction control active lamp circuit. The module drives the traction control active indicator, the lamp that flashes to tell the driver the traction control system is intervening, and it monitors that circuit for electrical faults. C1104 sets when the lamp control circuit reads battery voltage at a time the module expects it to be controlled, indicating the circuit is shorted to a power feed. This commonly results from chafed wiring contacting a powered conductor or a fault a...
