About C1299

C1299 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.

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.

C1299 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 C1299 indicates that the control module has detected an interruption or fault in the four wheel drive (4WD) control system, either as an electrical fault or as a loss of communication between the transfer case control module and related drivetrain modules. The system uses a transfer case control module, an electric shift or actuator motor, mode and range switches, and network messages shared with the ABS, ECM, and BCM to engage and monitor 4WD. C1299 sets when that control or feedback is lost, when a circuit is open or shorted, or when the transfer case cannot reach or confirm the commande...
