Cummins M11 code 413 is the Cummins troubleshooting document for the Datalink Circuit – Control fault (PID S249, FMI 9, SRT 00-608). The control data link lets the ECM communicate with vehicle control systems such as transmission controllers and the antilock brake system, and it is located in the sensor wiring harness. It sets a yellow warning lamp and lists the exact conditions, causes, and step-by-step checks a technician follows.

Who needs this Cummins M11 code 413 manual
Heavy-truck technicians, fleet maintenance teams, and workshop owners diagnosing this fault use it to confirm the code before replacing parts. During diagnosis citizens band radios and other radio devices are switched off during diagnosis, and ground lines are isolated from the CELECT harness to rule out interference. The step-by-step tree starts by reading active and inactive codes with the diagnostic tool, then inspects the harness and connector pins for bent, corroded, pushed-back, or expanded pins, flushing them with electronic contact cleaner Part Number 3824510 before any component is condemned. Test leads run around the bulkhead are used to isolate a faulty OEM harness, and the code is rechecked and cleared once the repair passes.
