NO code ? the first thing is to make sure all the fuse are good, the next thing is to connect a scan tool and check for readings to speed sensors.
Some of these use the wheel speed sensors to control the speedo and abs , the speed sensors in the transmission are used to control gear shifting, make sure the wheel sensors are working, the most common problems are the wiring to the rear sensor and the rear sensor itself, check on the rear end on the top and make sure connection is good and maybe replace that sensor and see what happens, i have run into this problem a few time but some were diffrent. one was a bad rear speed sensor another one was the cluster and the last was the abs module.
I would start with checking all the fuses first, then move on to replacing the rear speed sensor located on the rear top of the diffrential . good day.
The most common problem is with the ABS control unit. You will most likely have to replace it. It is located under the brake hydraulic unit (not the master cylinder). This part can be purchaced from a Volvo dealer, or sent to one of the many places that repair them. If you choose to fix it yourself, and would like the name of one of the companys that repair them, let me know.
This problem may be a fuse blown, or a faulty speed sensor, wiring for speedo, or other problems with speedo cluster. You said check engine light was on, this may be related to speedo. As computer reads vehicle speed it controls trans, engine, even radio volume as vehicle changes speed. Try looking for any blown fuses first.
i have the same problem with me 2000 montana. i was told that it was the tcc switch. it means that the torque converter is stuck in the on postion. to fix the problem i was told either to swap out the tranny with another used one or to have the switch replaced. the switch is internal and they need to drop the trans down to access the panel on the front driver side. the part is only $90 but its 3 hours labour.
there would either be a shorted wire or the computer is malfunctioning. The only way to fix this problem is to have a mechanic put a scanner on your car and test it. AUTOZONE DOES IT FREE other wise it's about $40
Check fuses because the one that controls ciggarette lighter can often blow and this can be a sympton of that,could be loose. Looks like a bad connection from one of the speed sensors which control the abs, do you get abs light stay on. Could be wiring under the bonnet,check all visible wiring too. Failing them it`ll have to be an auto electrician.
