I started to spend three hours searching old posts, but I figured I'd let someone stretch their "help a Crossfire brother" muscle instead

My boss's son has a 2005 Limited Coupe. Bought it in 2011, has had a few issues here and there but nothing major (most expensive repair was a water pump failure).

He texts me this afternoon with the following message:

Cruise quit working, spoiler won't come down. ABS/ESP warning lights are illuminated. Battery was just tested and is OK. Car runs fine.

Any ideas? Sounds like the BCM took a dump, but maybe it's something simpler?

Thanks all,

 

My first thought is to be sure all fuses are tested good.

 

Is the negative battery cable to chassis ground OK ?
( and STILL could be the battery, regardless of the 'test' )

 

Check for codes but I'd guess it is a speed sensor in a wheel.

 

He said he was going to check all fuses... isn't #19 the one that controls the wing?

Sound advice... I'll ask him when the battery was replaced. Trying to figure out how the wing correlates to the lack of cruise...

 

Dang you're impressive...

^^^ The OP of that thread had the exact same issue.

 

A bad speed wheel sensor caused similar problems in my na roadster.

 

The problem has showed up here before and I just had the same problem with a sensor in my rear driver side on my 300. The code said it was the front driver sensor, a new sensor there solved nothing and the garage I then took it to said it was the rear sensor and it was.
This problem with the code indicating the wrong sensor position has showed up on this Crossfire forum a while back as well.
My scanner did not show the error code, but the self diagnostics on my 300 found the code, U1417 which is ' Left front wheel sensor fault'. This of course turned out to be the rear sensor.
