Have a 97’e420 that’s got some weird stuff going on. When I crank it. I get the following errors. I get a check engine electronics and also ASR …ACC.skid control. It’s also in limp home mode. ( 2nd gear). And it also says to check break pads. Pads and sensor wires are fine.. Ran a code check on my scan tool. And I get a P1747.. Any idea what could be going on?
