Those position faults are likely from a power cycle. Common with the BP inputs over LON. TAC20s will drop MCC1 to turn off the starter with certain fa...

Ya, since you found the actual problem, I’d put all the old boards back in

2nd that, their videos are excellent. With an I2, my money would be on the lowering or check valve seats. These valves are super easy to pull apart an...

Not TAC20, it’s a TAC20-03. Try a GET command.

That’s a TAC20-03. If the GET doesn’t clear it up you’ll probably have to replace the CPU. You could try re-loading the software if you had a backup b...

It shouldn’t need it since it’s not actually doing anything but I found an old note that this fixed some odd syncing problems. It’s possible this was ...

Add it

You do have BLO in your IO map right? It should be port 8 bit 2.

If the original CPUA is still functional you can download the software right out of it and upload it to the new board. If it’s dead and there is no US...

You need to do an FJR to make sure the car can do a proper resync. You shouldn’t be getting a low pressure fault on a resync unless something is wrong...
