    ESP/BAS, won't upshift or go over 35mph, engine light & brake light flashes

    I have a 2006 Magnum 3.5l. I sent the PCM out to get it reconditioned, due to the O2 sensor heater codes, which appear to have been shorted out.

    When I went to install it, I disconnected the battery, installed it, reconnected the battery, started it up and took it for about a 3.5 mile ride.

    The ESP/BAS and the traction control light were on and did nothing when I pushed the ESP/BAS off button.

    After the “ding” the “engine light” blinks, flashes 9 times and blinks again, then stays on.
    The “brake light” flashes continuously
    It wouldn't upshift or go over 35mph and would shudder if I tried.

    I tried the three key method and got no codes.
    I tried holding down the “trip meter reset” for 4-10 seconds.
    I tried turning the wheels to the “left” and “right” then straightening them and got nothing

    I did not have any of these issues prior to reconditioning

    Is there any “Mopar Voodoo Magic” to get these things straightened out

    Your best bet is find out exactly what codes are in pcm. Did they knock out all learned items -VIN-tire size ect ? When it was reconditioned?

    very long shot, try to reset the gearing in the pcm.

    sometimes when i send a custom tune to the car it acts just like that ^^^ until i reset the gear ratio. good luck.
