TRAC on/off switch question(s)

Postby instarx » 14 May 2008, 11:09

I don't have one. Do I want one? The wiring and connector is present behind a dummy switch in the dash so I think just getting a switch would set me up. Saw one on Ebay for $20.

Is a TRAC on/off switch useful, and if so why didn't Volvo put one in my car - because it's AWD, maybe? Does anyone know under what conditions it would be useful to turn TRAC off?

For some reason Volvo decided to leave off the switch on 99 00 XC's and R's but you are correct, it IS hot and it WILL work if you install the switch.
A few of us just did with our R's.
When pushed it will DISconnect the tracs from the AWD system
You would turn it OFF if you were stuck in the snow and the other time would be if you're "drifting", something you probably don't have enough power to do in an XC

Thanks, seems worth it to get one if it could help get unstuck. I see some today on Ebay for $1. But I really don't understand how turning TRACS off could help getting unstuck in snow since that is what the TRACS system is designed to do when it is ON. Confused.

TRACS was a promise, not an actual functional feature. In my opinion. I believe the brakes were not programmed to be strong enough upon trigger of the TRACS system.

I've always been able to spin the tires on wet pavement or snow with application of throttle. I can hear the ABS system trying to slow the wheels, but it's simply a matter of the brakes not being applied strongly enough by the system.

When I was instructing advanced drivers I always found the noise the ABS made was enough to get them to ease off the power thereby restoring traction.

It is just something else to go wrong.
