2000 V70 XC Up Arrow Flashing

Postby eddym16 » Fri Jan 06, 2012 9:30 pm

Hello all,

I recently purchased a 2000 V70 XC SE back in June 2011, but about 3 weeks ago it started acting up. One day on my way home going about 55 MPH the up arrow on the dash started flashing (the one that lights up when in winter/wet traction mode). As I slowed down to make the upcoming turn the car started to buck and shake a little bit. As I then began to accelerate after making the turn the shaking continued and began to get worse, to the point where I pulled the car over and killed the engine.

I consulted the owner's manual to find that it was most likely something wrong with the automatic transmission. Knowing this I continued home shifting the car manually. The car drove fine.

The next day I drove the car to a specialty Volvo shop to have it checked out. They decided that the best course of action would be to reset the codes and do a transmission flush (which had probably never been done on this car and it has 150k miles on it). If that failed to fix the problem then they said it was probably the transmission and it would need to be replaced.

With the transmission flushed and the codes reset, the car ran perfectly for just over hundred mile (driving it in D), but then then same shaking began to happen when I was going about 50 MPH. Again I took it in for another diagnosis, this time to a Volvo dealership to get a second opinion. Their conclusion was also that the car would need a new transmission.

I have a heard time believing that this is the case though since if the transmission were indeed shot why would it have worked flawlessly for those hundred miles or work fine the rest of the time when shifting manually? As a side note the ABS light and TRACS light were both always on since I got the car, but my dad recently fixed the problem by making the ABS connection better. I think it involved a piece of plywood and plastic. Anyway it is no longer an issue. We're thinking it could be something to do with the computer or electrical system, since 90 percent of the time the car shifts and runs fine. We also recently disconnected the speed sensor to see if that would make a difference at all, and it may shift a little smoother but still hard to tell at this point. The check engine also is on most of the time but it's been that way since I've had the car due to a catalytic converter error code. The code that came up for the transmission though is 1618. Just wondering what the problem could be.

Thanks!

I am having a similar problem. My 98 S70 keeps shifting between Winter and Economy at one second intervals. My ABS and TRACS lights are also on. I believe the ABS and TRACS lights were on due to a bad ABS module. Maybe replacing the ABS module will fix our transmission problem also. Anyone else have any other thoughts?

1618 is a speed signal code stored in the TCM. It's there from when your ABS and TRACS lights were on, at that point the trans wasn't getting a speed signal or when you disconnected the speed sensor on top of the trans. You probably had a trans arrow and were starting out in third gear.

Any other codes in there, or just the 1618?

as for the 98, unless it's a late build 98, the ABS shouldn't be triggering the trans arrow/flashing e-s-w lights. Sounds like your trans arrow is flashing too?

Yeah, there was one other code but it had to do with the catalytic converter. Don't remember the number but that shouldn't have anything to do with the transmission. And yes sometimes the car would seem to start out in third gear, but not all the time when in Drive. So I guess the question is where do I go from here? Will a new TCM most likely fix the problem? Thanks again for the help!

A new tcm won't do anything. Something else is causing the transmission to act that way.

Are you reading the codes or a shop? Your regular obd reader isn't going to pick up the tcm codes.

So I just had my car rescanned with a different (more advanced) scanner by an auto mechanic I know and the 1618 code still came up but it also came up with "Fault in lead between AW 50-52 and motronic 4.3 (mil requested)." Hopefully this will give you a better idea of what's going on. Thanks.

Still sounds like your ABS module. You said the TRACS and ABS lights where on. Do they still turn on ever? Not quite sure what your dad did to fix it. Unless he took it apart and re-soldered the connection that go bad, then that most likely is your problem. I was having the same issues as you are describing. The up arrow would start flashing, car would buck and drive very poorly. would start out in third sometimes, and if I manually shifted it would drive fine. Check through my post history for more details. If it was me I would have my ABS module fixed by forum member Matty Moo at http://www.midwest-abs.com. I did and car has been great ever since.

So an update on the situation. The ABS module was recently sent out to Matty Moo, but my dad was driving it for about a week with no ABS module in the car and it seemed to shift perfectly, however the idle was a little rough. Once the replacement part came from Matty Moo my dad installed it and after about 40 or 50 miles the car went back into limp mode on the highway. The check engine light came on and the flashing arrow came back as well. The ABS and TRACS lights have not come back on though. Without an ABS module in the car the up arrow worked perfectly, coming on when in the winter/wet mode and also when in manual and the car needed to be shifted into the next gear. Not sure what the problem could be, but it seems to be something related to the ABS module but not the ABS module directly. My dad also rescanned the car with a new scanner and the codes that came back were P0756 and P0734. Thank you all again for the help, my dad and I really appreciate it!

What he said. Those codes are for tranny solenoid shift performance.

P0756 - "Shift Solenoid B Performance or Stuck Off/2-3 Shift Solenoid Valve Performance" code.
P0734 - "Gear 4 improper ratio".

How's the fluid look now? Another flush may or may not help...but usually the 'improper ratio' code is a bad sign.

I replaced the solenoids in mine, and it was a b@#$@ of a job. But it's fixed it to this day.
