ABS dash warning light following a sinking of the rear axle/tires

Moved to a new storage lot and got stuck there. Good news, a medium tow truck (F750) was able to winch us out. Given the depth of sinking I did a long look under the coach for possible damage (brake cans etc) and did not see any drivetrain related damage. Even ran a "CDL test" Air Brake test and came out ok. However, while enroute to another storage facility the ABS light came on. Is there anything I can check? wires? sensors' location for sand?

The ABS sensor is mounted on the brake backing plate and monitors a ring on the brake drum or disc. If it is disconnected or out of adjustment you get the light. The adjustment (air gap) is critical for proper operation. You may have disturbed it or it may be dirty.

If the the tow truck operator pulled you out by the front axle, take a look there.
He could have bumped a wire or sensor loose, if he wrapped the chain around the axle, out near the brakes.
