Circuit Description
Ignition voltage is supplied through ABS enable relay. EBCM energizes pull-in coil by completing ground circuit at EBCM ABS relay control terminal. Magnetic field created will close ABS enable relay contacts to supply battery voltage to EBCM, providing power to motors and solenoids.
Code 14 can be set anytime after EBCM commands ABS enable relay on. This test checks availability of current/voltage to motors and solenoids. Code 14 indicates voltage is not available, and ABS operation is not possible. When a malfunction code is stored, ABS is disabled and ABS warning light illuminated.
