/ Problem: 4WD light stays on.
1. Check the front driveshaft under your car. If you press the 4WD button to the off position in your car and you can't turn your front driveshaft then your solenoid is probably burnt out.

4WD VSV Replacement: Toyota P/N 88690-89132
Part Name: Valve Assy, Magnet
Price from CruiserDan: 17.77
No Discount Price from Toyota: 23.70
This part is off a 1988 Toyota Pickup. It's off the 22R Engine.


Tools Needed:
1. 12 mm wrench or socket. (unbolt VSV bracket from firewall)
2. Screw driver (remove bad VSV from bracket)
3. Angle grinder or file or hack saw (modify metal notch on VSV to fit original bracket.)
4. File, pocket knife, or razor blade (remove connector lip to fit original clip)

For reference: VSV = Vacuum Solenoid Valve

Steps to repair electronic 4WD in an FJ62 (mine is a 1988)

1. Remove Bad VSV (red one) This picture shows the passenger side firewall. You need a 12 mm wrench to remove the bracket. Unclip the wires and hoses. Make sure to label everything or keep it half hanging and connected like I did.




2. Unscrew the new bracket from the new VSV. We don’t need it. Also, take off the 2 hoses that come with the new VSV as well (not shown in pics)


3. Now we need to modify the new VSV before it will fit. Compare the two VSV’s and it’s obvious that we need to trim the metal tab on the VSV and remove the lip off the new electric connector. I had already trimmed mine prior to this picture so use your imagination.


This second picture shows the two metal tabs. They are different sizes. The new one is too big and needs to be trimmed down.


Wear safety glasses and use proper tools and techniques. Don’t stab yourself with a pocket knife while trying to remove the electrical connector lip. Point is, be safe.

4. Now that you’re new VSV is modified; check to see if the electrical connectors fit. Also check and see if the metal tab on the VSV fits into the firewall bracket you unbolted. Connect up the proper hoses. The vertical hose coming straight out the old VSV is the Vacuum line one. The new VSV Vacuum line is the one on the outside. I hadn't trimmed the metal tab yet, so again, use your imagination. Sorry for the lack of proper pictures.


5. Attach everything and don’t worry about sucking on the tube or switching hoses anymore! I have only just installed this. ***DISCLAIMER: Worst case scenario this VSV may burn out early. Who knows, maybe it’s not supposed to be used for this. I hold no responsibility for you trying this. I tried it and it works but I cannot guarantee for how long. My guess is that everything will be ok but I’m just letting you know, do this at YOUR OWN RISK.***

Nice find!

This would probably work good for the AC idle solenoid in the 60s.

[RockDoc]

Thanks for posting this up, I'll have to pick one up for a spare next time I'm grabbing some OEM stuff.

[Bomar]

Someone needs to put this under FAQ

[PhilC64]

Excellent find and write up Randy!

[Randy88FJ62]

I'd like to make a more official writeup that is cleaner to put on the FAQ but this is a good start to help those of us with electronic 2WD to 4WD .

I assume this VSV will work for most, including the AC idle up. The question is how much modification will be needed for the connector or bracket.

Is everyone sure the part number listed is correct? I called Toyota with the number and they said the cost was about $225 and the nearest one was Japan.

[Randy88FJ62]

I can scan or take a picture of the receipt if it will help.

Make sure to ask for this off of a 1988 toyota pickup truck. The ones for the land cruiser cost more because they were made in low quantities whereas there are way more tucks so production cost was lower.

Good write up, thanks.

It's in the FAQ.

The origional bracket can also be used, just take your time pinching the four lock "V's" back together and slide out. New valve will seat just a touch higher within bracket, but still fits. Seperate "V's" again to lock in place. Either way, great fix!

I just called the local dealership that I deal with,
Their price is $227.30 list (in Canadian dollars)

I'm guessing a serious typo is happening somewhere
Look at the part, the number if pieces in it, the function it performs and remember it's coming from a dealership. Do you think $23 is right?

[Randy88FJ62]

Call cruiser dan. He got it "special ordered" for me for $17.77.

[Randy88FJ62]

This is the second comment from a Canadian user that has had this problem with price...

Try Cruiser Dan and check back in.

I hooked up my battery last weekend backwards and blew the fusible links. I just got it running again and noticed that my 4WD light stays on. I just ordered another one from my local Toyota Dealership in California without discout and it was $27....

Just got finished with this STUPID EASY mod!
Took me all of 10 min. start to finish.
The hardest part is grinding down the metal tab if you wanna get all technical and precise about it. Id recommend using a dremel to make it precise. I used an angle grinder....wasnt the prettiest, but it worked.
Thank you sooo much for pioneering this. Its saved me a BUNCH-O-CASH!

You're welcome. I just took the idea off ih8mud and did a write-up. I'm not sure who we should thank for the initial idea.

[stash12]

Good info thank you. When i click my 88 fj62 in h4 it engages all four wheels are locked in, but when i go from h4 to l4 4wd doesn't engage i only have the rear wheels working. The 4wd display lights up and then turns off during shifting to h4, can you help me out please.thanks.

I have never heard of the 4wd light going off when going from low to high. The vacuum solenoid valves hold it in place until you manually push the button. Get under your truck while it is in park and the parking brake is on. You will know you are in 4wd hi and 4wd lo if you can not turn the front driveshaft with your hand.

Please clarify your question for me.

Just ran over this post by Spook50.

I'm pretty sure it's in the case. Either that or connected to the mechanical linkage in one way or another. The switch allows current to go to the 4WD solenoid when you shift into low range, hence automatically shifting to 4WD at the same time......as long as the solenoids are working

http://forum.ih8mud.com/60-series-wa...n-writeup.html

Seems that you may have some connection problems at the tcase, either mechanical or electrical.

[stash12]

thanks for replying. when i click on the H4 button my 4wd display lights up and all 4 WHEELS are locked in , then when i switch from H4 TO L4 THe 4wd light display turns off and only my rear wheels are locked in , basically i have no 4 wheel drive when switching from h4 to 4L. thanks.

[stash12]

i'll get under my rig and try the hand turning the shaft thanks.

[DirtyLittleSecret]

Thanks for the thread. Ordered three (replace both with new, and got a spare). Will be in tomorrow!

[stash12]

if you don't mind me asking, where did you buy your vsv's from. thanks.

Maybe I'm being incredibly dense but what's the purpose of the 4WD button if shifting activates the solenoids?
