ABS Diode: Description and Operation
DESCRIPTION
The system diode allows electrical current to flow in one direction only. It acts as a short (closed) circuit in one direction and an open circuit in the
other direction. This diode enables the four-wheel ABS warning light to illuminate when the ignition switch is "ON", the system is disabled and
the system relay is in the default position.
