2000 v70 xc obd2 codes

Post by Greg2545 »

I recently bought a Volvo that ran terrible, missing like crazy. But the car had good history and good bones. Got it home and replaced coils and plugs
Cleaned the injectors and ran well shifts well. Check engine light on and had not received my scanner yet, so went to autozone and had it scanned. p0722. Speed sensor. Bought one on eBay and waiting arrival Replaced the hatch release relay and locking mechanism along with the fuel filler door hinge. Everything I got I bought on eBay or A1 auto. Today I got the scanner and got codes for all coils and ECM code. Figured the battery might be low with the doors opened so much so I charged it now the code I get is a p1618. The car runs and shifts fine. What can I do What should I do. Newbie to forums and Volvo. But dang this car is cool!!

That code is typically a ECU / TCU communications error. Since it runs and shifts OK it may just need to be reset and I'm not sure that a typical OBDII scanner can do it since technically it is a transmission code. VIDA / DICE would certainly reset it and then you could see if it comes back. Sometimes the edge connectors on the modules can get cruddy where they plug into the socket and contact cleaner can clean them up.

The rub on the '99/2000 modules is that they don't pop out like the older models and technically it takes a special release tool to remove the modules. It is a major battle but I've managed to remove them with a metal paint trim guard by getting it into the slides at the bottom of the socket and working them back a little bit at a time. Once you get about 1/4" exposed on the back then you can slide the levers from the rear and it goes fairly quickly.

The socket is a weird ZIF socket and there are plastic rails that draw the module into the socket. The special ECU tool is pricey, about $75.00 as I recall, and it isn't a tool that has any other utility to it.

I would try getting it reset with a DICE unit first. A bunch of us on the board have VIDA/DICE and I have scanned and reset stuff for some other members in the area. Perhaps one of our members in your area can give you a hand.
