The fuel pump on my 2009 smart car quit. I puled the pump and checked it out to verify that it had actual failed. It had but the car still would not work so i started looking at the SAM unit. Sure enough the pump relay in the SAM unit had failed. I did some checking and a new SAM unit will cost $1500 plus the cost of reprogramming the car to accept the unit. The car is only worth $1500. I have a rule that i will pay no more for repairs than the car is worth.
I have made the decision that as the current SAM unit is worthless as is i decided to open it up and see what is inside. I removed the circuit board and found the relay. The relay is a $1 item ($16 plus shipping in the US). The problem is with removing and replacing it. There is another circuit board mounted directly over the top of the relay. It looks like the only way to remove the upper circuit board is to un-solder it.
Has anyone else worked on a SAM unit and have information on how to remove the upper circuit board.
