Why Do Engine ECU and Vehicle Electronics Faults Occur in Winter?

ABS and ESP warning lights and the engine management light coming on after a cold night do not necessarily mean that a control unit has failed. Voltage drops, a discharged or ageing battery, moisture or water entering the vehicle’s electronic modules may be the cause.
