Hi all. Just started driving my new to me eldorado and am trying to work out the cobwebs. The ABS, Traction, and Stability lights come on on startup Code is always c1243. Pump motor stalled If you clear the code when engine is running and headlights are off code does not return If you clear the code when the engine is running but loads are on the code immediately returns. You can hear the motor kick on but it acts like the voltage drops too low and trips the code, also the lights dim. If you shut the car off and immediately restart it lights are out and no codes. I also noted something else interesting tonight, If you accelerate hard the headlights dim a bit and come back when you let off. Here is what I am thinking, I am thinking there is a bad ground or battery connection somewhere, but am just not sure where to look. I am also thinking that this is why the abs pump code shows up. If the voltage is lower than normal to the abs unit then it will stall the pump. Battery is new, tests good. 12.6v at battery and cluster Alternator is new and works good. No driveability issues other than the lights dimming on hard acceleration. Engine runs great. trans shifts smooth. No other codes from any other system Dash lights, and interior are bright. I could use some insight on this one as I think there is logical explanation. I was as specific as I could be so I hope it helps. Thanks all
