About C118C

C118C is a manufacturer-specific chassis diagnostic trouble code recorded for Infiniti vehicles. 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.

C118C 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 Vehicle Dynamic Control (VDC) / ABS control module communicates with the Hybrid Electric Vehicle (HEV) or Electric Vehicle (EV) control system to coordinate regenerative braking, torque control, and stability functions. DTC C118C is set when the VDC/ABS module receives a fault status message from the HEV/EV control module, or when HEV/EV system operation is restricted due to an internal hybrid system fault. This indicates that stability or brake control functions are being limited because the hybrid or electric drive system is not operating normally.
