Need a little help to track down a recent problem. Car is 1995 E320 wagon (W124.092) with ~220K miles. I'm getting the following three codes and they appear to be related.

DM/Pin 3: 20 Vehicle speed signal not present

Pin 8: 28 VSS - open circuit

Pin 14: 9 Left rear axle vehicle speed sensor or Hall-effect speed sensor
Rear axle vehicle speed sensor from ABS control module
Rear axle vehicle speed sensor from ETS/SPS control module
Incorrect CC/ISC control module installed ETS signal

The only thing I've done recently was change out the rear diff bushings but the CEL and ABS lights didn't show up for about a week. Now after clearing codes, the CEL shows up after two start cycles and the ABS light comes on every time after moving forward.

Anyone know where I should start?

Thanks!
