brakes coming on at will

[maltb]

I have an 06 sport that is acting up. My mechanic pulled a communication error code ( dont know which one) a few weeks ago because my abs light s were on. Now I don't have any lights on but at speed or when accelerating it feels like my brakes are coming on intermittently. Any suggestions on where to start? Rest of story...about 2 weeks before the warning lights came on I was buried to the bottom of the doors in beach sand trying to launch my boat at a "really good" remote launch. Any help would be great. thanks maltb

When my alignment was Off the esp was bugging out on the road but a wheel speed sensor might do that but I really don't know.

What'd poor Will do to the brakes to make them come on at him?

you may have sand packed into your wheel speed sensors, and you may have an alignment issue like bubba said.

Is there any way you can get the code?

I've had wheel sensor problems before, but a wheel sensor code always came up. This time the code was communication error. I'll try to get the number tomorrow.

It's probably steering angle sensor. Go get your alignment checked. Most shops do it for free.

A "communications" error, may be just that. ChecK the wiring to the sensors. If buried to the doors, you may have compromized the insulation on the wires, or got water in the connectors or???

The mechanic cant rememeber the code so I'll check what I can on the wiring and get him to rescan if I cant find anything. Thanks

pulled the codes again today got 3:u1417 implausible left wheel distance signal received, c1027 l rear wheel speed sensor signal erratic performance, c 1020 left rear wheel speed sensor circuit. Obviously I need to check the l rear wheel speed sensor, any ideas on the u code?

they're all related; take the sensor itself out and clean it, then clean the tone ring.

Haven't worked on any '06-7s so not totally sure if it's an open tone ring, tjkj should be able to chime in.

Pulled the sensor, checked wires , cleaned it and re-installed. So far so good. Thanks for the advice. maltb
