Generally, that is certainly telling you that there is a difficulty within the transfer circumstance — hassle codes ought to be set, so have your automobile scanned by your mechanic. I haven't any working experience Together with the 4WD company mild, so in addition to that, I have no more data.
We want to admit you and your business to your fantastic determination to customer service....
But my automobile appeared so superior, I had been reacting like I gained a whole new auto. Jon along with the receptionists were being Specialist and delivered excellent service. The icing on best was the vehicle detailing at the top. That's it, we're married.
Hmmm… doesn’t sound just like a TCCM issue… Appears much more like an encoder motor dilemma, or potentially a transfer situation problem.
You are going to have to give me some more details — like what, specially, have been you accomplishing after you bought the support light-weight to head out? What is the process carrying out now, if everything? Have you ever checked All of your fuses (even those underneath the hood?). Did you look for corrosion on at the TCCM?
OUCH! That hurts. Yeah, this is basically the reason which i put this details up to begin with. I had a absurd quotation initially, and they (the dealership) hadn’t even checked out it — they had been just likely to begin replacing pieces.
Rudy states: March 24, 2008 at 3:38 pm I'm obtaining a problem with my 4WD not likely into 4HI, I press the button and nothing at all transpires. I place the truck in neutral and hit 4LO it goes in, then I press 2HI and it goes back. Once i have it in neutral and press 4HI both 4HI and 4LO lights flash and afterwards goes again to Visit THIS WebSite 2HI. I study that should you jumper pin 13 on the info connection cable to floor, then switch critical to your ON place the lights about the 4WD buttons flash a code, so I attempted it and positive sufficient a code of 2 flashed meaning motor/encoder failure.
Essentially, it feels like the method is examining the neutral swap and may only actuate in neutral. 4Lo is purported to operate by doing this, but 4Hi need to activate the fly.
You have a cordless telephone — you choose it up and push the speak button to get a dial tone, however you don’t have a dial tone — alternatively, you obtain a number of beeps following a couple seconds. What is happening is, you push the button on the cell phone (buttons with your dash) — a signal is distributed within the mobile phone to The bottom device (Transfer Situation Command Module) — the base unit is not plugged in, so it does not respond to the sign within the cellphone — the phone doesn’t know what to try and do, so it beeps at you to convey there is an error. This is often, basically, how your 4WD procedure functions.
I have Chevy 2001 Blazer. The challenge I had is I am able to’t turn on the 4Hi. So I went to dealership. The repair service costed me $900 to switch the TCCM.
The very first thing I might Look at is definitely the 4Hi light — (keep it very simple) — does the 4Hi light ever appear on?
Okay, so how the heck am I likely to deal with this? I can only imaging what GM would wish to do (browse as “harness substituteâ€â€¦ $$$$$$$$$$$$$$). And from asking around about obtaining a alternative plug, my only possibility will be a scrap garden.
Basically, I am amazed it engaged as though I keep in mind accurately, the vacuum swap communicates With all the TCCM and generally leads to the dash switches to flash if no conversation is gained. It's been a while because I labored on this automobile though (and marketed it in ’07), so I could possibly be mistaken.
