OBD2 Codes after car wash
#1
![Default](/forum/images/icons/icon1.gif)
Took XK in for car wash, ran some errands, the next day I started up the car
and got the following codes:
P057B - Brake pedal sensor
P0500 - Vehicle speed sensor "A"
U0121 - ABS
U0122 - Vehicle dynamics control module
I would suspect the car wash got one of my speed sensors dirty, and need to clean it?
Any other suggestions appreciated.

It does sound like one the speed sensors on each wheel is playing up but is it actually showing faults on the dashboard as these could be one-off faults which are now historical.
If the speedo is also showing inconsistent readings it will be one of the rear wheels, I believe, and will be a live issue. In that case, as a first step, I would unplug each sensor, spray contact cleaner of both side of the connector, and the plug and unplug the connector a few times. If that does not result in the faults disappearing, then you need to do a search to see which sensor is "A" and replace it.

Update: indeed it was a low battery from the car wash.
what bothers me is l if the battery is low usually my infotainment system will warn me and shut off the stereo.
this time there was no such warning, just failure to power
Up my modules (central junction box?) Leading to
no ABS, adaptive dynamics, traction control and parking brake,
