Troubleshooting Extinct Platforms

trouble codes showed ABS pump, swapping it didn’t help

Apparently a common hack

I see jumper cables, guessing that’s a 12 volt battery access point

CEL = Check Engine Light

Power Limit means no high voltage

OBD or CAN port on Win7

OBD = Onboard Diagnostics

CAN = Controller Area Network

He is only running can low and can high, common misconception. It can work but it is unreliable. At a third wire. Ground.

I don’t care what anybody says, CAN IS A GROUND REFERENCED DIFFERENTIAL SIGNAL.

Yes I know the difference between single and it and differential communication. Yes differential communication is still ground referenced. Yes you can get it to work without ground. Yes you will waste hours and hours and hours and hours and hours and hours and hours.

I don’t care if that’s how an OEM did it, they did it wrong.

COM 3.08

That’s just a standard packet logger presumably, with some basic parsing, Running at 38,400 baud

You have to make sure CAN low and can hi are oriented correctly

Looks like he is about to use sublime, That’s a free editor. He’s probably going to be parsing hex (hexadecimal)

Now he’s using something called savvy can which he says he got off of GitHub. No doubt it just has a lookup table of different parsing patterns

He is parsing against this DBC file downloaded from the think forums. That’s just going to extract the packets and interpret them

It’s just pattern matching, You can do it by hand but it takes a while

PAUSE

Let’s go do it on the real thing
