I'm working on trying to get the board to function on the test bench so I can do this without going back and forth to the garage. Once I have that figured out I'll start trying some aldl messages.
I don't have all the equipment with me to test that so I'm working on mapping the ADC pins on the processor. It appears there's an unused analog input on E8 / AN6. The components aren't populated so it isn't actually connected to E8 but the pads and traces are there for it to be.
I can't tell for sure but it appears there's a voltage sense circuit on both AN0 and AN7. One heads towards the power supply section and the other receives power from rail side of the fuel level sense resistor. I'll have to dig into this with the board powered up to figure out which is which. One might be for battery voltage and the other for the 5v rail / brown out detection.
The rest are accounted for as such:
E7 - IP Dimmer - AN3
E9 - Fuel level - AN2
E10 - Ambient light sensor - AN5
E11 - DIC buttons - AN1
E12 - PASS resistor - AN4
Part # on the ones I have is 16223622. The other pn RockAuto has a cross reference for is 16230561.
