Got this error message today. Any thoughts on where to begin?

Marginally slower than the blink of an eye. (The average time it takes for a complete human blink is about 300 to 400 milliseconds or 3/10ths to 4/10ths of a second.)

Nothing helpful there?

Well, yes, the internets turn up about a dozen things it *could* be. Ranging from ABS ring, speed sensor and steering angle sensor. Usually, its been my experience that there's one thing that is most common when things like this pop up. That's why I asked the forum.

I pulled some codes that indicated something amiss with the left front. I pulled the speed sensor and everything looked OK. It did have a bunch of grease on the end of it, I assume this is lube to keep it from getting stuck (I've had that happen on a Subaru before). I cleaned it, re-installed and the error went away. We'll see if it stays away.

LoL r u related to bedrck?

List the codes and maybe someone can assist.

Codes C1201 and C1141

 

[chuck s]

c1201
c1141

As you suspect both codes point to the left front wheel/ABS system. C1141 decodes to "missing tooth" on the ring. Any damage there? Despite the computers in the car the sensor is just a steel toothed ring running by a sensor.

Do the ABS brakes work?

[Matt_N]

No idea. If I ever need to brake hard enough to activate the ABS, I'm doing something wrong.

I think it may have just been a dirty sensor. I removed and cleaned it, and it seems to have reset and hasn't come back on. So far.

Did you unplug it too? The code specifically mentions "short to ground", it's possible the seal in the connector is cracked and some water got in and shorted the connection.

Whenever I unplug a connector for any reason, I always spray it out with electronic cleaner spray, and before it goes back together it gets swabbed with dielectric grease. I imagine it saves me a lot of future headaches and keeps the contacts and spades clean and corrosion free. Cheap insurance. Glad you fixed it for free! That’s always a win.
