“Acd/ayc pump has completely stop working in my vehicle. I took my vehicle to be service and the person who was doing the service on my car told me that the acd/ayc pump has gone out and I need a replacement. I found that weird, because I have not driven my car for roughly about a month and for an issue to pop up was very weird. After doing research, I seems that multiple people have the same issue were these pumps go out unexpected. There are only 1400-1600 of these cars made year in the states and to see many people have this problem in the u.s. …”

“My car began to have a flashing active yaw control light on the instrument panel. It was determined that ayc/acd pump was failing due to severe corrosion. When this happens, the awd stops functioning, so the car is now in two wheel drive mode. Mitsubishi mounted the ayc pump in the rear fenderwell area where it is openly exposed to the winter elements such as snow, salt and sand. This is a very well known problem and the dealer I went to has done about 6 cars in the last month or so just for this problem. The car was taken to a local Mitsubishi dealer for warranty repair. …”

“Tarmac icon blinks incessantly on the display panel, as one drives. The blinking can cause photosensitive epilepsy (pse), which is a form of epilepsy seizures triggered by visual stimuli that form patterns in time or space, such as flashing lights, bold, regular patterns, or regular moving patterns. I found out later, the blinking is an indicator the acd pump - active center differential - is failing and it's only a matter of time before the component completely gives out. …”

“When cold temperature comes (around 20f) or below you can hear a very loud whine coming from the ayd/acd pump located in the passenger side wheel well when first staying vehicle. When this happens there will be a moment where the tarmac/gravel/snow indicator lights on the dashboard blink and puts the pump into failsafe mode. If you drive while the pump is in failsafe mode the handling is terrible and any engine braking is non existent. Over the past few winters I have experienced this up until this write up. …”

“The ayc pump failed by displaying a blinking tarmac light. It constantly flashes while driving. The ayc pump correlates with the steering and stability control for the rear differential. This is a big hazard. The ayc pump should be relocated to the trunk compartment so it is not exposed to weather conditions like snow and rain. This will protect the ayc pump from failing. The warranty will not cover this failed pump at all.”
