1998 Mercedes S420 has a warning light problem.

When the key is turned on all warning lights illuminate, then after startup, 2 lights remain - ABS, BAS/ASR. They stay on solid even before the car is moved. They never go off at all, and have this problem for 3 months solid.

THings I have checked:

Battery voltage - 12.6 off, 13.96 running constant, batt looks great and is white merc battery.

Fuses underneath black cover at PAX side of eng compartment, there are 3 - red, yellow, blue. All good, no corrosion, has 13.9VDC while engine running.
Brake light switch operation - when the pedal is pressed, all 3 brake lights come on, then go out after released. Lights do not stay on due to a faulty brake light switch, and then bring the batt down.

Please note that the brake lining light is not on and nor is the red brake light warning against brake fluid level.

I have not reset the neg connection at the battery, but I did unplug all 3 computer modules under that black cover in the eng compt. When i reset them, the lights did not change behavior.

Question? The black thing that the fuses plugged into, was it the ABS module? I kinda thought it was the skinny black one next to it. I could not get the one with the fuses out (and who knows it may not come out)

I have learned all i can from the past forum searches, now I need to create application specific assistance. Please chime in and lets stay on topic.
