Code C2116 Description

The C2116 diagnostic trouble code indicates that there is a low voltage condition in the ABS pump motor supply. The ABS (Anti-lock Braking System) pump motor is responsible for pressurizing the brake fluid in the ABS system to prevent wheel lock-up during braking. When the voltage supplied to the motor is insufficient, it can lead to decreased performance of the ABS system, potentially compromising the vehicle's braking capabilities and overall safety.
