I tried using my 4wd for the first time the other day. When I pushed the button I could hear a relay click down towards the center console and the light on the dash starts blinking but the light never goes solid. I waited about 2 minutes before I finally shut it off. I've never had a 4wd vehicle before so I'm not sure if I'm not waiting long enough or if I should hear sounds when the system engages or what. I haven't looked at my Hayne's yet to troubleshoot but if someone can provide any headstarts I'd much appreciate it. :D

Hello,
Could you give us a little more info on your truck? Is it a Trooper, Rodeo, Amigo(Rodeo Sport)? Also, what year is it. Where you moving, and if so, how fast. Post back, and I am sure someone will be able to assist.

Sure. It's a 2001 Rodeo. The manual states to drive under 60 mph while engaging, so I've ranged anywhere from 15 to 50 mph the numerous times I've tried to engage - all to the same results. I also checked my Haynes manual and there's virtually no troubleshooting information for the 4wd system.

Sounds like your shift on the fly (SOTF) actuator is rusted/seized. On the rodeos it's a small electric motor operated gear box that's attached to the drivers side front axle tube. They are prone to moisture contamination & will lock up if you don't "exersize" them. The only preventative measure I know of is you have to remember to engage & disengage your 4wd a few times a month to keep it lubed/freed up. I do it as I pull out of my driveway & disengage before I hit the street. Atleast that way you dont shock the drivetrain too bad. There is a very small gear lube resevuoir on the SOTF where it attaches to the axle, that should be okay for you since your truck is only a 2001. You either have to take apart & clean the SOTF actuator, or replace it.

Joel,

Do you happen to know what the actuator looks like? Is it hard to remove for cleaning (i.e., do I have to remove a lot of other components?)? Thanks!

Wow, I was staring right at that thing yesterday and didn't know it! Oh well. I ended up dropping it off at Isuzu this morning to just let them fix it under my warranty. Would've liked to try to fix it myself but ah! no time this week. I'll post the end result. Thanks for the info guys!

Yep. The SOTF actuator should be covered under the 3yr/50Kmi isuzu warranty. It is not covered under the 10yr/120Kmi p-train warranty.

Good deal! :D Remeber to turn the 4wd on/off every couple of weeks & you'll be good to go.
