Ryan says: April two, 2008 at 9:24 pm Thanks for that response to my article before, and i experienced pep boys do a vacuum test about the method plus they explained each individual matter was seemed to be Okay, so I purchased that 4 wheel drive swith from napa and put in it,(it went in to the front axle right where the cable in the actuator attaches), nonetheless no luck. so i could see some form of sensor in addition to the transfer circumstance with three vacuum strains connected to it, so i replaced i, and Once more even now absolutely nothing, so i have a couple far more inquiries…their is an additional sensor on the tail pice with the transfer scenario, I had been instructed it's the pace Management sensor, could that be the situation?
You will have to offer me some additional information — like what, specifically, have been you undertaking after you received the service light-weight to go out? Exactly what is the system undertaking now, if something? Have you checked ALL your fuses (even the ones beneath the hood?). Did you look for corrosion on with the TCCM?
Regrettably, I have not experienced expertise with your unique issue — nevertheless it does sound like it could either become a) the same dilemma as I used to be obtaining (ie. inside gears / forks in the transfer scenario not permitting comprehensive shifting from a single mode to the other), or b) a front axle swap difficulty (which is located within the Electricity Control Module (PCM) — but that’s about all I will let you Using the PCM as I don’t even know where by it’s Found).
The very first thing I'd personally Check out will be the 4Hi light — (hold it basic) — does the 4Hi light ever arrive on?
My 4 lo will perform. And that i listen to the module click on when it moves into 4lo. but Once i consider to move into four hi the lights flash then goes directly to 2hi. I used to be questioning If you're able to plaese assistance?

PS – the flashing swap lights suggest the procedure is trying to talk to the remainder of the procedure. When it stops, it means it couldn't communicate with Component of the technique.
No, I don’t Going Here have just about anything AFAIK — but I do Possess a buddy that has the All-Information system and might have it (he printed out some great schematics for my TCCM yesterday) — I’ll talk to him these days and when so I'll post it below for yourself.
Repeat at the method at the back of Each individual tire. So long as you use string or wire that does not extend, you can get an exceedingly correct measurement in this manner.[six]

As for the encoder motor being fried as the TCCM “received corroded and shorted it out” — once more, it doesn’t seem prone to me. There are (off-the-prime of my head) seven wires between the TCCM and also the encoder motor. two of these are electrical power (+/-) and therefore are FUSE safeguarded. four of them are sign strains and the final just one is sign ground. If the ground wire was corroded and shorted (to what?
Hi Les — I didn’t know that Raymond experienced uploaded them to your file server — I assumed they were part of a web-site that saved that facts (ie.

It doesn’t audio like it’s the same sort of system, so I’m not really certain what to recommend to you personally. My system is often a purely electronic a single (where you thrust a button, which activates a motor to change modes in your case)… yours seems like a mechanical process in which you engage the 4WD manually (ground shifter) and The sunshine comes on only being an indicator.
