The MPM (Multi Power Module) manages power distribution and voltage conversion for various electrical systems, often bridging between the vehicle’s main battery and a secondary electrical circuit.
If you notice any of the following, the part likely needs replacement:
Multiple electrical systems malfunctioning simultaneously
Warning light related to the electrical/power system
Diagnostic fault code related to the module itself
Installation information
Mounted centrally in the vehicle, connecting to multiple electrical circuits via the wiring harness.
Frequently asked questions
This module distributes power to several connected systems, so a fault here can disrupt power supply to multiple circuits simultaneously, even though each system itself may be perfectly healthy.
Super good! They came through with the part I needed, quickly and at a fair price! Thanks, and I definitely recommend!

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
