This summary uses the existing diagnostic information shown in full below.
This code means that the computer system in charge of keeping the car stable and safe has detected a problem and is not working right.
The Vehicle Dynamics Control Module (VDCM) monitors the stability and traction of the vehicle. A watchdog error indicates that the module has detected an internal fault or has stopped responding properly.
The C1111 code is triggered when the Vehicle Dynamics Control Module's internal watchdog system detects a malfunction. This could be due to a software glitch, a hardware failure, or communication issues within the module or with other systems.
• Stability control warning light on
• Traction control system may be disabled
• Erratic vehicle handling
• Software glitch in the control module
• Hardware failure in the VDCM
• Communication issues between the VDCM and other modules
