In my owner’s manual (2008), in the section on TCS (traction control system), it states that
“If you press and hold the TC button for five seconds, the traction control system will turn off and a TRAC OFF message will appear on the DIC.”
However, in the next section on StabiliTrac System, it states that
“If you press and hold the TC button for five seconds, the StabiliTrak system and the traction control system will turn off. When this is done, the STAB SYS OFF message will be displayed on the DIC.” It also states that StabiliTrak is automatically disabled in 4LO Lock mode.
I don’t remember which message (TRAC OFF or STAB SYS OFF) shows up when I press and hold my TC button; I’ll have to check when I get home tonight. Maybe it depends on which mode (4HI, 4HI Lock, 4LO Lock) you are currently in? I’ll have to try them and see if the DIC message is different, and then I'll report back here.
So it is still unclear on whether you can disable BOTH systems by turning off the TC button. Don’t you just love corporate doublespeak?
EDIT: OK, checked the operation of the TC switch last night; regardless of mode (4HI, 4HI Lock, 4LO Lock, 4LO Lock w/rear diff locked), the TC button results in "STAB SYS OFF" message in the DIC. Never does the "TRAC OFF" message appear. The only time I've ever seen a TRAC message was when I was having electrical issues that gave me "TRACTION FAILED, STAB SYS OFF, REDUCED POWER", and that had nothing to do with the TC button.
