" all signs of the above point to the ABS Module" hum?

Dealers seem to start with the most profitable. I start with the cheapest or easiest. Even it does not fix the expensive, it builds my confidence.

Codes?
Battery. battery terminal. ground connection.
One fog light stuck on. Does the other light. Check all lights.
I would expect speedo problme to mess with ABS but would be surprised to learn that the ABS kills the speedo but I am still in the learning mode.

"could this module cause the misfire issue" Exceeds my wildest imagination.

Please keep us posted.

Here is a sample of why I learned to "love" dealers: Friend with Volvo goes to dealer with ABS light on intermittently. Dealer charged $1400 to replace ABS module. On the way home light comes on again. Returns to dealer. Dealer reports loose connection. Which came first? Bad ABS or loose connection?
