Professional repair service for Detroit P23519308 Engine Control Modules, used on DDEC III and DDEC IV systems with Detroit Diesel Series 50 and Series 60 engines — 1994 to 2001 on-highway and 1994 and later off-highway.

This module is also referenced as R23519308, E23519308, 23519308, 23530725, P23530725 and AP80041.

Common faults we see: blown fuses, no communication, engine shutdown, stored and intermittent fault codes, injector driver failures, and oil or water intrusion.

Repair and return: your ECM comes back fully reconditioned, bench-tested, and ready to install in the same vehicle it came off — saving you the time and expense of having a new ECM programmed. Backed by a one-year warranty. Mail-in service across all 50 states.

Diagnostic policy: we diagnose the unit first. If it is not repairable or no fault is found, the cost is $200 plus shipping, and we process a partial refund for the difference.
