Actually, it looks like the program is checking the neutral switch and may only actuate in neutral. 4Lo is alleged to function this way, but 4Hi really should switch on the fly.
I'm able to right here the encoder motor activating and deactivating. I'm wondering In the event the mechanics did anything on the transfer circumstance throughout rebuilding with the transmission. Anyway, what may very well be making this hissing sound in or near this transfer situation.

My initial concern will be, Exactly what are the lights on the sprint carrying out (the 4wd pushbuttons)? And 2nd, what yr of car or truck are we conversing? (I’m also assuming we’re even now talking about a Chevy Blazer.)
Push the vehicle on to a flat area, jack up the entrance conclude, and location the car on jack stands. Make sure the steering wheel is unlocked.
However it reveals in “4 wheel lower” I really feel my upcoming go is eradicating the front drive shaft , and pulling the servo shift motor within the transmission , it appears as In the event the are close to 9 wires likely to that servo motor, I’m I on Visit THIS Site the best tranck ?
Like I claimed, I'll try to make sure to get some additional pictures — ideally this will let you obtain your module even though! Regards;
$ten to repair your 4WD — great! Many thanks for sharing that info with myself and my viewers — I’m positive it may help a number of people today conserve a huge amount of $$$!
perplexed states: January 4, 2009 at 2:52 am I've a 4WD 2000 BLazer that gained’t disengage from 4HI. Once i press 2HI I am able to hear the TCCM clicking along with the lights flash on 2HI but goes again into 4HI. I also attempted 4LO Which does the exact same point. On the other hand, it does go into Automobile 4WD with no issue. I’ve experienced the turn on the sprint replaced (the letters within the old one particular wouldn’t light-weight up).
Rudy claims: March 24, 2008 at 3:38 pm I am acquiring a difficulty with my 4WD not likely into 4HI, I press the button and very little happens. I set the truck in neutral and hit 4LO it goes in, then I push 2HI and it goes back again. After i have it in neutral and press 4HI equally 4HI and 4LO lights flash after which you can goes again to 2HI. I go through that when you jumper pin 13 on the data hyperlink cable to floor, then convert vital on the ON position the lights over the 4WD buttons flash a code, so I attempted it and guaranteed ample a code of 2 flashed meaning motor/encoder failure.
There is a schematic (on site one) in the front axle swap — it seems to be tied to ground by way of a “pull-down” resistor. When engaged, it ought to be pulled substantial (+5VDC or +12VDC, I don’t know what it’s working with with the change).
As I said to a poster over (two up from this one particular), it Seems to me like it may be a button assembly, wire among the button assembly and TCCM or possibly a TCCM difficulty.
