1999 V70 Shifter Up Arrow Problem

[Matty Moo]

Yes, that's the strange thing. I can see the ABS and SRS. I even reset the SRS light after I fixed a lose wire for the side airbag. ABS is good. All this when in the Volvo 1998 V70 library mode specific for this engine...But NO TCM there.

Do you have a 98 or 99? Thread title says 99.

On my Autel, TCM shows up for 98 s70 but not 98 v70. If you have a 98, then select 98 s70.

precopster - Thanks for the location, I am out into the garage again

Matty Moo - It's a 99 V70, B5254S Denso injection with an AW50-42 tranny. Ya, I noticed that anomaly on the Autel analyzer. I have used to other selections (98, 2000, S70, etc) and seen the TCM, but as I indicated, I see no TCM codes. I can reset the TCM, but no success of relieving the blinking up arrow light. BTW - the 98 models are quite different engine wise (coil packs vs distributor for starters) but I believe both FWD cars have the same 4 speed Automatic (an AW50-42)

Did you press the "W" button on the center console by chance?

[DavidsVolvo]

That was the first thing I tried, but it appears that the W button has no effect at all. You may know this better, when the winter mode is on, doesn't the light on the dash stay solid and not blink? Blinking arrow only means TCM fault, correct?

Summary to Matty Moo and precopster... I found that on the Autel MD-801 I am able to see the TCM when setting for a 1998 S70 and a 1999 V70 both having the AW50-42 tranny. HOWEVER, there are no codes present on the TCM for either of these diagnostic library selections when used. Regardless, I reset te TCM anyway. I also cleaned the Temic TCM pins, but they were very clean.

Now that I am quite sure that there are no tranny faults registered on the TCM, how about a faulty "W" switch? If this switch has failed in the on mode, would the up-arrow light always blink? BTW...I appreciate you guys hanging with me on this, I hate losing! However, I'm beat and quitting for tonight. More tomorrow.

The W switch is a simple on/off arrangement. You may be needing more advanced diagnostics for that vehicle and your particular fault. It can be as simple as a faulty PNP switch

The only solution I can suggest is to try something really simple like a Torque Pro on an Android device (reads my TCM just fine on the 2000 V70 with Temic computer) or borrow a different scanner and if this doesn't work then get hold of Vida/Dice.

In fact I had a trans code afew weeks ago which gave me a flashing arrow while driving with Torque connected. The car was taking off in 2nd or 3rd gear (felt more like 3rd) Unfortunately I only performed a clear without reading however later hooked up Vida/Dice and found a stored transmission code.

I just don't think that particular Autel has the correct setup for your car or has a corrupted file in it. Is that model programmable? Does it come with an application to add or delete car maker files?

[DavidsVolvo]

Yup, after reading about the Autel MD801...it is not supported by the Mfg and has no SW updates available even by 3rd party suppliers. Autel seems to have dumped it for some reason (bad product?). What I am reading from this analyzer is all I am going to get. Time to invest in the Android App and an interface...I have the droid phone. Do you have more details on the Torque App and the Blue tooth reader?

precopster, Matty Moo and whoever else may give me the next diagnostic test to go after...Here is the latest.

+The TCM connections are clean
+The PNP has been removed, cleaned and replaced
+While up on blocks and in drive; No TCM, ABS SRS or Engine codes present with Autel MD801 MaxDiag tool.
+Up arrow is still blinking
+The car has 3rd and 4th gear and shifts fine between then when in "L", "3rd" and "D" on the shifter
+There is NO 1st or 2nd gear present.

If I am missing 1st and 2nd, does one of the solenoids control those two gears? Like S1 or S2?
What next?

[precopster]

A Vida/Dice is perfect for your situation because it has Activations where you can switch on individual solenoids and listen for their co-operation.

A great company to get tech info is ATSG. For a small fee you can download a tech manual for that transmission so you can learn about the solenoids and what they do.

Vida/Dice has little in the way of info about the transmissions apart from servicing with fluid. However it has great info on removal and replacement procedures.
There's a Matthews valve body removal in the Repair Database under P2 V70 which can be used for your P80 to get at the valve body cover.

For now however READING your trans is so important. A ELM327 bluetooth reader iand a Android device with bluetooth is all you need to get started. It can be a pad or a phone.

Thanks precopster, you've been a great help. For $20 (Bluetooth & Torque Pro) I can't go wrong, so I ordered it. You are correct, I must get more analysis info before randomly replacing expensive parts. So, I will get the Torque pro & ATSG info, if that doesn't pinpoint it, I will move to investigating the Vida/Dice. BTW - I already took off the tranny pan and looked at the solenoid pack...what did I expect...it looks clean, but no gross problems like wires broken.

You know, it's real strange that I can't read the TCM and if I read it for another year, it says no codes present. So, I believe either I have a bad control module (TCM) or one of the solenoids is bad...or the stupid Autel is lying to me.

BTW - I have 3 Volvo wagons. 1998 V70 Standard shift, 1999 V70 Automatic, 1999 V70 XC. The Autel works on all present modules on the other two cars, but not the 1999 V70.
