Hello,

My car was sitting for a while and wanted to take it for a ride last weekend but the car didnt start. ISTA tells me that there is no communication between the DME and the EKPM. But the pump doesnt run neither, normally it should run at 100% as failover.

The fuelpump runs if short wired. So i bougth a second hand EKPM2 but I have the same symptoms with the second unit.

So I began to check the wiring. The EKPM recieves 12v. The wakeup signal also has 12v.

On PT CAN high and low i get 2.25v and 2,55v.

The resistance between PT CAN high and low is 40ohms but should be 60 right? Resistance between PT CAN and ground is 12,5kohm

When I disconnect the EKPM from the bus I get 60ohm between high and low. I get the same result with both EKPM modules. Are both modules fried? Or may there be another issue?
