    So i have a 2010 Sport access cab.. snow and ice storms like crazy these last few days in North East Pennsylvania... if i turn Trac Control off.. the LSD kicks in.. why is this.. Ive found it better in other vehicles to go through this garbage without Trac Control.. any way to disengage both of them whne wanted?? i need some input.!!! Thanks.

    Now, for visual aid... all traction options possible (4WD OFF ROAD TRD):


    This was posted in its own thread... but may be helpful here as it shows the dial, buttons and lights that are touched and light up for the various drive modes:

    Recently some have posted that the truck was 'stuck' in '4WD' because the light was on or blinking... only to later learn it was just the differential lock switch pushed in! That light is below the 4WD light...

    The lights are different... So, I just took some photos so we all can see. Let's go through the levels of traction activation and see what it all looks like:

    [​IMG]

    Normal dial position for paved roads or where traction assistance of 4WD (four wheel drive) is not needed.

    [​IMG]

    The lower switch, next to mirror controls (car with skid lines below) is the VSC OFF switch. This also activates AUTO LSD when in 2WD with a quick push. Auto LSD is traction control without the engine output regulated.

    [​IMG]

    This is what comes on with AUTO LSD active. The VSC OFF light goes out above 30 mph.

    [​IMG]

    If you stop the truck and hold down the VSC OFF switch for 3+ seconds, VSC and TRAC both turn off for open differential(s) in H2 or H4.

    [​IMG]

    Go into H4 (4WD High Range) from 0-60 mph if you need more traction because of poor conditions or off highway needs.

    [​IMG]

    This is the 4WD High Range indicator light... two differentials and 4 tires. TRAC in H4 has no engine regulation, the same as AUTO LSD in H2.

    [​IMG]

    For more torque to power through deep snow or mud or to climb up or down steep grades, stop truck, put tranny into N (Neutral, not Park), and rotate dial to L4.

    [​IMG]

    Low Range 4WD indicator light. VSC goes off in L4 and both differentails are open.

    [​IMG]

    If your 4WD Tacoma is an '09 + Off Road TRD, you have 'Active Traction Control' (A-TRAC) that provides the 'brake-locking' of any non-traction (spinning) tires front or rear for tractor like crawling/ climbing. Gives traction control while in low range. Push this switch just once when in L4 and A-TRAC will activate when-ever needed to keep moving while in L4.

    [​IMG]

    A-TRAC activated light.

    REAR LOCKER:

    [​IMG]

    As Toyota states, use only as a last resort and turn off when out of trouble.

    [​IMG]

    While in L4 (for 4WD Tacomas), press the RR DIFF LOCK switch. (I engaged it twice today while stopped)

    [​IMG]

    The Rear Differential Lock indicator is the x'ed rear differential image. If it doesn't engage, or if it is pressed while in H4 or H2 (for 4WD Tacomas) it will BLINK! Remember, when locked there is no differential action to allow the tires to rotate at different speeds, as needed when turning.
