About C1219

C1219 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 C1219 is stored, the module has detected an open (broken or disconnected) electrical path 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.

C1219 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

The ABS module drives the ABS warning lamp in the instrument cluster on hard wired systems by switching the lamp output to ground while monitoring the line for an expected response. DTC C1219 sets when the module detects an open circuit on the ABS warning lamp output path, recognised by an absence of the expected return current or voltage when the lamp is commanded on. This is more specific than the generic circuit failure code and points the technician toward broken wires, blown bulbs, or open driver pins rather than shorts. When this code is set, the ABS warning lamp typically fails to illum...
