    U1408 code and U1408 -only- no other codes 2006 300C SRT8

    U1408 implausible brake signal ... this happened yesterday on my 2006 300C SRT8 that just turned 14,000 miles. Bone stock drivetrain other than suitcase delete. No custom tune, any aftermarket parts, etc. Was sitting at a stoplight and the ESP/BAS lights came on with a chime.

    I've also read mentions of people getting this after power braking. I hadn't been doing that either, just literally sitting at a light waiting for it to change before jumping on the freeway. Car seemed to be running/driving normally including functioning cruise control, for about a 30 mile trip. I mention that since other posts I've read about U1408 they said their cruise quit working.

    Didn't have the lights on for the trip back home, but checked codes this morning and only came up with U1408.

    Some time I wish for the days of mechanical cars...

    Since the ESP/BASE lights are now off, I would consider it a fluke for now.

    Good luck.
