However, I don’t have any serious expertise Together with the service 4WD light. As I stated to my visitor beneath (just the get I answered the posts), it always indicates a difficulty inside the transfer case — hassle codes need to be established, so that you may need to own it scanned by your mechanic.
Dan claims: December seventeen, 2007 at 8:33 am I have a ninety nine′ S10 Pickup and 4wd functions good although the front generate shaft is not going to disengage within the axles when switched to 2wd. Essentially the transfer case is switching from 4wd to 2wd however the front axle is often engaged. I traced the cable cable again to the vacuum actuator beneath tha batery and located the cable just isn't sure up however the actuator alway has vaccuum to it regardless Should the auto is in 2wd or 4wd.
In the event you look at the schematics, it is possible to see the motor is actually “managed” via the TCCM by way of signal wires. I suppose it’s probable that if one of many motor wires had been being shorted it might lead to damage to the TCCM — do I feel This is actually the case?
When your toes hit anything on the appropriate… you have found the kick panel! This panel is snapped on, nonetheless it does hook under a number of other plastic panels, so be a little bit watchful with it.
I really don’t provide the knowledge to state definitively yes, or no — but I desire you the ideal of luck. Make sure you, let's know how you make out.
Loosen the lock nuts. Concerning the tie rod and each tie rod finish can be a nut that holds it set up. You'll need to loosen this nut with a wrench. Remember that on some vehicles, the motive force's side lock nut may be threaded counterclockwise, even though the passenger facet is threaded clockwise.
I’m likely to email you, as I would want to receive a hold of your diagram — hopefully you’ll let me write-up it below to save folks some time (and you from having to e-mail it out to personal individuals constantly).
Some how the procedure thinks the 4Lo button is staying pressed, Which’s what you must find. Sad to say, intermittent complications would be the hardest to search out.
Apart from that, it’s possible that you just obtained a bum encoder in the components store, but how likely can it be genuinely? Test what I've said higher than and publish back here if items nonetheless aren’t Functioning as they must and we’ll see what else we can consider then.
Greg suggests: December 19, 2007 at one:22 pm Thanks for the additional ideas. I wound up just getting it in to the shop for the reason that I was in more than my head as soon as I obtained beyond observing the shaft turning and the necessity was urgent (truck doesn’t drive really worth a darn in ANY number of snow w/o 4wd).
Now, if you DO listen to the “click on-click on”, then your TCCM is Functioning and wanting to change into 4WD — the problem, IMO, would then be While using the module that is definitely over the transfer scenario (I fail to remember the term for it at the moment) — it is an easy “motor” set up that merely moves the transfer situation gears to the correct method.
I’ve intended to look at the heating technique since like final Wintertime — just never manage to get all-around to it (probably ’bring about I don’t utilize it in the summer… WHEN I come to feel like repairing it!
In essence, take a look at Each individual of your strains — if they are all warm even though in 2Hi, then when you attempt to change to 2Lo, among the list of traces really should go low (0VDC) — the exact same should really take place with 4Hi. So, if you are trying to engage 4Hi and you also’re guaranteed There exists energy at pin five (4Hi button signal), and none visit their website of the strains alter when seeking to change to 4Hi, I'd suspect the TCCM. In the event the encoder signal line DOES change, then the transfer situation encoder motor module is undesirable.
What it looks like, to me, is really a wiring challenge — most certainly between the encoder as well as TCCM (underneath the kick panel). Have you ever pulled the kick panel and had a think about the TCCM wiring (as pictured int he 1st submit of this web site entry)?
