The video I mentioned before said, on his car, if you follow the wire bundle from the diagnostic port, there's a 'side branch dead-end' where a bunch of wires are joined, that you could remove the insulation and find shorts by selectively disconnecting wires. So something that's only powered when key is in run position, but not the ABS module itself? I don't know the expected result of port test with key off, so I don't know if that's relevant. (Just checking what I can without more tools.) Removed the key, pressed radio power, it plays. Turn key on, I saw it blink to red, back to green, then to red and stayed there.ĪBS module disconnected, key on, still K1 short.

What is the LED on the cable supposed to to? This time I watched it. I know it couldn't auto-detect and I had to choose the model. I think it's either a B6 or B7 A4, but I'll have to check. This was the day after I tried to scan it, and I didn't bring my laptop to try another scan. Solid green when connected and key off, solid red when key on. I saw a video where someone said his cable flashes red when there's a short and he connects the cable to the car, not even connected to the PC. Port test shows Status: Questionable, K1: SHORT TO GROUND, K2: OK, CAN: Not Ready Tried connecting specifically to engine and abs, and it couldn't connect. It looks like a stock radio, but I haven't asked yet. When the scan was complete, the only faults it found were for the radio.Ġ0858 - Connection Radio Intermediate Frequency (IF) Output to Antenna Amplifier Thought I'd run a full scan and give him the results. That's all I know about the problem, except he said the speedometer was not working. Trying to scan a friend's car, who said his ABS wasn't working, and he replaced the module, and it's still not working.
