I have sent a 5v square straight from the sensor on the diff. Watched it with a scope to make sure it was a clean signal. I cleared the code also but DME is just not translating the message.
Pin 83 has 12v on it without any speed input.. that's why I tried tapping it to ground trying to fool it into thinking it was a 12v square.
I dont know if it should be 5v or12v signal and if it should be pure square or a pull down signal.
The ABS module does effectively connect through the Rxd line, pin 88 I believe, but I don't know if they share data on it.
My frustration level is escalating. Its pretty fabulous otherwise, if you can live with the lumpy idle. And I can! |
