Code C1200 Lincoln Description

When the driver stops too fast, and one or more wheels begin to lock up, the ABS system takes over. It sees the wheel or wheels slowing down too rapidly by way of wheel speed sensors. When this happens, it shuts off brake fluid to the wheel with the inlet valve/coil, and releases the pressure with an outlet valve/coil. The ABS Inlet Valve Coil Left Front is typically found on vehicles with 4 Wheel Anti-Lock Brakes. The ABS system checks to be sure that the coil electrical circuit is ok every time the key is turned on and the ABS module is powered up. If there is a problem with the wiring to the coil or the coil itself, the ABS module will communicate over a data bus to the instrument cluster to turn on the amber Anti-Lock Light and the Red Brake Warning Light, and ABS will be disabled. In this case, the module has checked the wiring to the left front inlet valve and has found battery voltage when it should have much less. This sets a C1200 in memory.
