That's awesome. I've always been somewhat perplexed why the PEM wasn't designed to communicate over CAN to monitor ECU duty cycle input and pump PWM control /supply voltages and report basic faults. When you open the thing up the board certainly appears to be far more complex than what, quite frankly, need merely be a relatively simple solid state PWM current signal relay. I find it interesting that Bosch/Ford/Volvo designed this critical system so that proper diagnostics in every single case requires aftermarket tools as the DICE units don't have external probe/scope functions.
