Volvo vnl Multiple ecm's problems out of nowhere

Ok.

 

One more find. If I have my ohm meter on pins C D. Red tester lead on C, black tester lead on D then I have 34.4 ohms if I switch it black on C red on D then I get 84.4 ohms . Key off battery connected. If I disconnect negative battery cable on either testing position then reading 59.7 or so. What the hell is going.

 

Hi Andy i m there i have my controller in my hands and the PN is Ok but mine it s a older version i think. A -7349 A. I already checked the data link pin out and the value red. Are you confortable to give me a phone number Face time ?

 

Ok

 

Ben,Thank you thank you and many more thanks.

 

Guys, did you figure out the problem?

 

The (shifter key pad) was the problem. Long time ago.
