Hey I was wondering if anybody has run into this issue. I am not in the States but before I left I noticed my TC2 button would not light up on the dash or anything when pushed. I have used it before. I was wondering if this is a common thing. I have a Diablo Programmer in which I used the Performance Tune but, I don't know if this has an effect. My family is watching over my beloved H2 right now but I was wondering if anybody else has run into this issue Thanks in advance

 

The TC2, 4X4, and Tow Haul switches are notorious for going bad. Take a multimeter and test it based on ON/OFF I dont remember the pinout on the switches but its simple enough to pull it and test it.

I've had to replace my 4X4 switch module twice

 

just remember the H2 must be in Low Lock for Tc2 to work.

 

Good point, I assumed that was understood when I replied.
