Warning lights

[hotboxn]

Any idea why VSC, Trac control, ABS, and Hill Assist lights would all come on at once? I tried pulling the negative for 10 minutes and putting it back on, but no luck. The only thing I've done is install the shorter springs for the coilovers. Any ideas would be appreciated.

only happened to me once. After my car was on the dyno and i started the car for the first time after my car did that (which i later found out was normal). Went away in like 2 seconds.

Are the lights still on in your car or did they go away?

Had the codes run at Honda and it's throwing wheel sensor along w/ a few others because it was sitting for so long at Gthaus, the voltage read really low. Once its back up to full charge, they'll clear them and see if they stay away.

I bet a wheel speed sensor either broke, or the wires got pulled and are loose at the sensor.

All 4?

[MachVEvan]

Yeah,

The traction control would certainly be effected. The ABS light because it is a ABS sensor. The hill assist, I'm sure, is part of the ABS system. When the sensor is tripped, it will send all modules into limp mode, shutting them off and giving the driver a light show.

If the light persists like yours is, it means the fault is found on initial system boot. That means a broken wire or broken sensor. Unless it is a chassis computer fault (which is very rare), it's gotta be a wire or sensor.

And ofcourse the dealer doesn't want to touch it to try and find out which one it is. I appreciate the help, I'll prob end up trying a different dealer to see if they'll attempt to locate the problem.

Try a visual inspection, should be just that easy

[hotboxn]

It's the wire that goes in to the hub correct?

[MachVEvan]

Yes, there should be a brake line and an ABS sensor at every corner.
