Some possible causes for demanding an ECU.

• Spiked by careless welding, i, e. MIG welding without disconecting the battery. True
• Obvious sign of mechanical damage to the to the encloser. False
• Encloser seal damaged and with obvious sign of water ingress. Tru

Often the ECU will be misdiagnosed as faulty, usually because the techician is inexperienced in faultfinding.

• Faults are much more likely to be with connections or sensors. True

Discuse how these ECU issues shold be incorpirated into diagnostic practices to test an ABS system:

Then control signal to the hydrolic moderator which brake pressure in the system. Vhecle use anti lock brake system monitor it self and if a fault will switched it off, and the ABS warning in the dashboard, will remine an in show that there is a fault in the system.
