1995 850 cruise control inoperative

Svenska · Post by **Svenska** » 10 Sep 2015, 16:51

My cruise control stopped working a few weeks ago. The code I retrieved says that there is no signal present (I think the code was 113 or 133...) Does anyone know where the sender/pickup is for that speed signal for the cc?

I am not familiar with that code but the speed sensor to the speedometer on a 95 is mounted on the transmission, sort of near where the oxygen sensor connectors are located. I would give it a look. Check out this recent thread for some pics: https://www.matthewsvolvosite.com/forums ... p?p=376652

Neither of those codes is a valid code for the cruise. Did you read those codes from port B-2?

Wow, I got that DTC number wrong... I did obtain the code from the B2 port. It's 122 "speed not been above 35 kph or no vehicle speed signal". Where is that speed signal? The speedometer works.

You always get the 1-2-2 if the car has been turned off. It is a silly code since you can't really read it while you are driving down the road.

There are a bunch of things that can fail with the cruise but the procedures and the Mode 2 diagnostics in the factory manual are an excellent resource to sort things out. If you don't have it the factory manual is here:

One of the most common failures isn't dealt with in the manual and that is the hard plastic line that goes between the area under the battery and the firewall, it has a tendency to crack and leak.

I fixed the cruise on my '99 S70 by changing out the stalk with a $10 junkyard part. a bad switch is a pretty common problem and pretty easy fix.
