Hyundai Common ECU Faults

This is a very common problem that causes the ABS light to come on and/or the "ESP button" to illuminate.

The engine ECU's fitted to these models are notoriously prone to failure. The problem lies with the type of capacitors used in side the unit that are prone to damage from voltage spikes. Even the voltage spike from an starter motor has been known to blow one of these ECU's.
