• EEPROM Checksum
• ROM Checksum
• RAM Checksum
• RAM Malfunction
These are all checks internal to the module itself. Any module that has a *550 code needs to be replaced. For the code to be read the module must have power and ground and the data line must be functioning so if you can read the code the module is bad, nothing else to check.
If at first you don't succeed suc harder.

'00 Silverado ecsb 4x4, 5.3 and riding on 285's...newest vehicle I've ever owned, loads of fun, and I've got cupholders!
'75 GMC 3/4t 4x4--355, 4spd, 205 t-case, 14 bolt full floater.
Built to haul a load--10+leaves in the rear, 1000lb overload shocks, 5 leaves in the front. Bulletproof and built like a brick sh*thouse!
