button 4x4 dash console,I had been without 4x4 for a bout 7 months and
finally came across a part I needed which was the TCCM computer, after
replacing it my 4x4 started working ..., it worked for about 1.5 months
and I am having issues with it again.,
what is happening when I first installed the TCCM I heard 2 clicks from
the box upon the ignition start and the 4x4 was working great shifting
all modes, however after a while my service 4x4 light came on again and
I was stuck in 4 hi, after checking the connection to TCCM replugging it
I was able to free my truck off 4 hi to 2.
Now I am scared to even switch , I noticed upon te ignition start the
TCCM now clicks 4 time and goes into blank mode showing "service 4x4"
dash light..., I am gonna inspect all the hoses today and the vaccuum
actuator, I also tried to clear the computer unplugging the battery for
more than 1 hour...., can anyone help , what do the 4 clicks coming from
TCCM mean ??? ,
Could that be some electrical problem ??? I also noticed that in my
Jimmy when I turn the ignition half way to get the dash on with the
radio the TCCM engages and then when I start the engine it resets and
engages again.. , is that normal ??, how many clicks should the TCCM
make on vehicle start, when it was workinig it made 2 clicks upon
ignition start and again 2 clicks upon engine start, now its double at
each stage and it goes into the service 4x4 mode...
any help would be greatly appreciated.
thanks,
Andrew
There is still no 4wd. Is there a problem in the differential? If so, is there something specific I should look for?
Anyone have any ideas how to fix this?
i got lucky.... hope it works for you!
