ABS Codes

Hi, all,

I'm new to TW.
2005 Tacoma I4 2.4L


Yesterday I got my ABS light on. I've been searching Google and TW and haven't found much. It threw four codes on the reader:

C0205: Front Speed Sensor LH Circuit
C0215: Rear Speed Sensor LH Circuit
C1241: Low or High Power Supply Voltage
C1249: Open Circuit In Stop Light Switch Circuit

At the same time my ABS light came on my left turn signal arrow on the dash illuminated. The turn signals all still seem to work but the left indicator on the dash stays permanently green back-lit.

Edit: I cleared the codes and they all came back on at the next start-up.

I have no idea what could have caused all four codes to throw at once. I took my truck to the self wash and power-washed underneath (nothing crazy, I do it all the time) -- maybe that could have done something? Other than that, I just went on a 500mile trip. I have no clue where to start with these codes or even what they're related to. If it were just a sensor I'd probably be fine, but this seems more complicated. Any help?

Thanks so much, from a newbie.

 

That's very interesting, I can't find anything that would cause all those codes to set at once unless you got water in the ABS module connector.
Have you tried clearing them and seeing if they all return?

 

Yep, I cleared them and they came back. Where is the ABS module? Is it underneath the car or in the engine bay?

 

It's in the engine bay on the right fender, has a bunch of brake lines and an electrical connector.

 

Looks like this
