Got on the car last week and the cluster lit up like a Christmas tree, abs light, bas esp, e brak light, brake light, check engine light all came on. All gauges work except the speedometer, traction control isn’t working, and the spoiler won’t go down. I’m not gonna lie tho, maybe I’m wrong but it feels like it’s making more power

 

THe the power feed to the Brake Controller has failed. This is either the fuse on the RCM, the Traction Control Relay on the RCM or fractured solder connections on the RCM.

What I would do:
1) Order a new RCM, put it in and be happy. ($140-165 depending on where you buy it.)
2) Take old RCM, put in box, ship to DJ for reworking ($65, shipping back to you included).

THIS way, the next time the RCM fails, and they WILL fail eventually, you have a spare in the trunk. Like I do, cause 1) and 2) is exactly what I did when mine failed.

Order this one: (And the website tells you it wont fit the Crossfire; the website is wrong.)

The solder joints are not fractured, they are dry joints because the parts were not heated high enough or there was a dirty surface.
What would make them fracture as any vibrations are the same for both sides of the joint.
