When ever you get caught in the rain you WANT to turn OFF the 'nannies' push and hold 'traction button' until both the traction control light and ABS come on. You want control NOT the computer. Same a do NOT drive a car/truck in cruse control in bad weather.
Agree entirely with EjFord on this. The nanny computer is designed for dry roads. In wet weather if one front wheel slows in a bit of water, the nanny puts the breaks on the other wheel an sends you into a skid.
I was very lucky, I was in the outer lane of I-40 and the right front wheel hit a puddle. Nanny slammed brakes on LEFT front tire causing me to skid anti-clockwise and slide left across 3 lanes of interstate.
I counter steered (turn right INTO the skid), foot off the gas. Wheel speed eventually equalized and I regained control of the vehicle. I was close enough to the concrete divider to literally reach out and touch it. God was with me and my Wisconsin winter driving skills helped save my life.
Pulled off the interstate, got a hotel to shower, cry a bit, and change my underwear, then headed back home. Still raining much of the way, but with all nannies OFF, Ruby behaved like a real lady & gave no more trouble.
Remember: one click of the T/C switch turns off Traction Control (REAR wheel only.)
Holding the switch for 5 seconds or so turns off Stability Control (FRONT wheels only).
Would LOVE it if I could mod this into two different switches, but as it is ECU software, I don't think this one will happen.
Just be aware of how your vehicle works and drive appropriately. Y'all be SAFE out there!
