The one other matter which i can recommend is often a “house fixâ€. Definitely, I do not know what sort of trouble you are possessing, but Permit’s suppose that you've got sprint lights and The sunshine DOES Visit the four×4 substantial (or small) place — at this stage, hear see if you listen to a definitive “click on-click†coming within the TCCM.
Anyway, skip forward… all went nicely final weekend, but I even now had a broken four×4 to cope with. And, like Murphy hasn’t already done ample, it’s the vacation period and many places are only open some odd times. That made items tricky After i learned what I required to look for!
I'm able to’t show you which way is which, but mark it where it truly is when you start and go from there (A method will probably be 4Hi, one other 4Lo).
I pulled in excess of and checked the fuse — every thing was excellent there, but I decided to transform it just in case. Nevertheless very little. After trying every thing I could think about, I just experienced to manage it and carry on on in 2 wheel generate.
Ryan suggests: April 2, 2008 at 9:24 pm Many thanks with the reaction to my write-up previously, And that i had pep boys do a vacuum check to the technique plus they stated every matter was seemed to be Okay, so i bought that four wheel push swith from napa and put in it,(it went into your front axle ideal where the cable with the actuator attaches), nonetheless no luck. so i could see some sort of sensor on top of the transfer case with 3 vacuum traces connected to it, so i changed i, and Yet again nevertheless very little, so I've a pair far more issues…their is yet another sensor on the tail pice in the transfer situation, i was told it's the velocity control sensor, could that be the situation?
Fastened that and nevertheless no 2hi. Once i attempt to modify from 4hi to 2hi I'm able to listen to the encoder motor & vacuum solenoid to the firewall do their work and also the Handle module clicking so I presume it’s undertaking it’s job. I've two lights on dash leading to worry, ‘Assistance 4wd’ & ‘ABS’. Would the abs program fault stop it from likely into 2hi? I know your not a mechanic but have you any facts for me?
I ment to say, I had my transmission rebuilt 2 months ago and the 4wd worked then. I put my Blazer on jack stands and began tracing the hissing seem (air leaking?). I’ve discoverd the hissing sounds is coming through the transfer case.
I actually sat right down to do a little Focus on the website yesterday, coupled with updating my backup travel — that’s when the issues started out. Anyway, before I flip this write-up right into a rant… I possess the schematics sitting suitable in front of me, all set to be scanned the moment I am able to get this machine restored.
I can be wrong using this, but primary logics (as well as schematics) tells me to start investigating the wire that stops the TC from shifting Should the A/T is in gear.
Effectively, that’s one which I haven’t read still. The “ATS†fuse (which can be marked “ATC†on this schematic) supplies 12VDC to 2 significant orange wires extra resources with the TCCM (marked as pins C18 and C19 over the schematic). As I stated, I haven’t seen this issue right before, so I haven’t traced that part of the process. I am able to only think (yeah, I understand!) that the for the reason that these wires offer 12VDC, These are used to operate heavier items such as the encoder motor (5VDC, which can be The sunshine guage orange wire, is useful for logic — ie. to run the “chips†on the circuit board). With any luck ,, it is possible to see where I’m likely with this particular. I’m just striving to consider it logically — If your fuse is blowing that materials 12VDC, what during the 4WD process would use 12VDC?
For each your aforementioned assistance, I've checked the module to check out if there is any obvious corrosion but there isnt any. have any plan regarding how to deal with this??
The flashing gentle signifies the method is attempting to enter that manner. If it stops flashing before it does, there was a dilemma getting to that mode. Sad to say, I’d say cease driving it and acquire it to a mechanic ASAP, if You can not more diagnose the situation.
Upon chatting to a few yards, they seemingly just take these modules out ($$$$$$$) and simply cut the connector off and promote it with the module. So, that basically only leaves me into a scrap lawn that permits you to walk around… and haven’t eliminated the module… don’t wanna go there.
No difficulty in any way… which was my sole intention… to aid others with an identical challenge (and help save a ton of cash also!).
