Ok, first off I'd like to say that I've seen many posts about this issue. However, I've isolated my problem to a specific problem that I think warrants a new post regarding my particular situation. I have a 2003 Sorento EX that only has the Auto and 4wd low switch. When I put it in Neutral and switch it to 4wd low, it goes in no problem. But when I switch it back toAuto, it stays stuck in 4 Low and won't come out and the drivetrain lightblinks on the dash. I have an OBD2 scanner tool and donít get any codes. So, I pulled the small electric motor off of the transfer case and can turn the rod clockwise until it stops and that essentially puts it back into Auto. I've tested the motor with a 12 volt power supply (battery charger) and it will turnboth clockwise and counterclockwise, no problem. But when it's connected to the vehicle, it will only go into 4 Low, turning counterclockwise looking at the triangular rod coming out of the transfer case. It won't go back to Auto, which is when the motor should turn clockwise. Iím thinking itís the TCCM, but would hate to throw $150 at it if itís actually something else.
Brief history on my rig: When I bought it I didnít know anything about Sorentoís. I had a Hyundai Santa Fe that got wrecked. So I got the Sorento with the insurance money. I have loved it ever since, but was not impressed with the 4wd. I have gotten stuck several times with only the driverís side rear wheel spinning. I finally researched enough to find the elusive fuse#13 was blown. I put a new fuse in, and viola! The TOD worked great and it even went into 4wd Low. But it wonít come back out. For only $150, I think itís worth replacing the TCCM, but thought I would ask around first. By the way, the Stealership (I love that phrase!) wants $150 to look at it and is already telling me the motor is bad, even though they haven't seen it and I can make it turn both ways with an external power source.
