Among other ABS codes, I'm getting Code 11 (module failure). I have two parts broncos and I swapped their modules in and I'm still getting Code 11 as well ad two additional sets of codes. Are the codes coming over with the used module(s)?

Is there a way to erase the codes from a used ABS module (say, on the work bench) before swapping the module into another vehicle.

I read the Helms instructions for clearing ABS codes (pasted below)...and they don't address the goal of simply clearing ABS codes before swapping a used module between vehicles.

Searching FSB produced very little useful info related to ABS Code 11; I'm guessing I should begin by cleaning the wiring harness connection pins. I'm hoping to save the ABS control module(s). Has anybody ever had a code 11 and been able to save the module?

Helms Instructions...for clearing codes
'93-'96 4WABS
Manually Clearing Diagnostic Codes: All diagnostic trouble codes must be output, all concerns corrected (anti-lock light off) and vehicle driven about 40 km/h (25 mph) before diagnostic trouble codes will be erased.
Note: Do not raise vehicle on hoist and accelerate to 40 km/h (25 mph) to simulate driving the vehicle. Erroneous sensor codes will be set.
Automatic Memory Erasing: A diagnostic trouble code will be automatically erased if no system concerns occur for 50 ignition cycles.

Ok, I'll answer my own question. ABS codes are stored in the ABS module. Disconnecting the ABS module from a battery for one year doesn't clear the codes. To replace, just swap the used replacement module into your Bronco and drive. In my experience, I thoroughly cleaned the electronic connection with a dremel tool and contact cleaner before installation. I drove around town for one afternoon. After several ignition cycles and about 20 miles, the old codes disappeared. I tested the abs on gravel road. I now have ABS and no codes.
