open connectors at wheel well? - gudgeonpin - 11-17-2020

I've had an intermittent (ok, mostly on) ABS light for about a year.  So, I've been wondering why.  The other day, I was looking at the inside of the driver-side wheel for the millionth time and noticed two connectors that were not connected to anything.  At first, I thought they were mates (short optimism), but then saw they are both male connectors.  
Tucked up in front of the wheel on the driver side with a bundle of wires- there is a plastic anchor as well that isn't anchored.

Anybody else see this on their vehicle?  This is a 2017 Venice.  Other than the ABS light, it runs just fine.

lol.  What dealer?  Nearest one is 200 miles away.  And I bought the vehicle in a different state.

Send the dealer a pic.

I have a 2018 VV.  If you look under the hood and the cowling (behind the dash) you will find a dozen unused connectors.  I believe they just used the standard wiring harness from the Chevy Cruz (or Sonic) which had a lot more components to connect.  I don't think any will cause a problem.  That said, maybe your ABS isn't connected properly.  There is a wire coming off each wheel bearing assembly.  If possible, follow each wire as far as you can, looking for a disconnect.

I just read something about a battery tender connects there.  Not sure what your looking at, perhaps thats it.

Brian- they are fairly small gauge wires, and the wrong connectors for a battery tender. Good idea, though.
Vector-BFC- that's a very good idea- simple and actionable. Cheers-

The wheel rotation sensor (hereafter known as WRS) in my (former) 2019 Venice GT was bad and had to be replaced. The dealer replaced the entire wheel bearing assembly. No sure about how to check this but here is a possibility. I expect that if you jacked up the front, disconnected the wire to the WRS and attached a voltmeter, you would see a pulsed voltage as you rotated the wheel. Likely only 1 side would be bad. If you see the voltage on one side but not the other, bad WRS might be the culprit. HTH and good luck!


RE: open connectors at wheel well? - gudgeonpin - 11-19-2020

Hi J Patrick,
It is likely either that or the space between the sensor and wheel is off. Very anecdotally- When it is hot, and left out in the sun, the ABS light goes off. A couple times when I jiggled the connector to the wheel sensor it went off.
As you might guess- this isn't real high on my list of crises to deal with Wink. BI will someday, but the weather was really nice today so I drove instead of worked on it.

You can use a voltage meter on the wheel sensor by lifting the side of the wheel and spin while monitoring the meter.

you should set the dial to AC on the meter and it should read about 200 mili ac volts!
