ABS and Advantrac Warnings

I went over a speed bump to fast and now I am having issues with the ABS and Advantrac Warnings lights now going off. I went to Advanced AutoParts and the only code that came up was B1234. Any ideas?

You could've smashed the rear ABS sensor or it's wiring. It is located on the top of the rear differential.

BTW the B1234 code means: Mirror Switch Invalid Code. Perhaps this has something to do with the programming for preset buttons 1 & 2. Try setting your seat and mirror positions again then saving them as presets.

How do you know it is the rear ABS Sensor?

I don't know for sure, I'm not there to inspect it. I'm theorizing that the impact from driving too fast over the speed bump forced the rear axle to bounce to the point of damaging the sensor.

Assuming we're talking about his namesake (2003Navi), it has independent rear so the differential is mounted solid to the chassis. Each wheel has a sensor/ring and I'd suspect one of them was jarred loose or out of alignment.

Was the scanner at Advance able to read chassis codes? If not, you will not see the the trouble code for any abs/advancetrac problems.
