ECM

Browse diesel engine control module listings and compare the exact manufacturer number, engine application and stated condition. An ECM, cab controller, transmission controller and aftertreatment controller are different sale items. Confirm the function of the module you need before choosing a replacement.

Part selection, fitment and ordering guidance

Check hardware, engine identity and programming

Send the VIN or engine serial number, original module number and any hardware or calibration identifiers available on the label. The installer should confirm the required software configuration and whether programming services or manufacturer access are needed. ATP does not promise those services simply because a module is listed.

Compare the listed module function and connectors with the original component.
Review whether the item is new, used or remanufactured and which components are included.
Use manufacturer service information to diagnose the vehicle before replacement; a fault code or no-start symptom alone does not identify a failed module.

Check the listing for new, used or remanufactured condition and current availability. ATP is an independent reseller, not an authorized manufacturer dealer. ATP warranty terms and return eligibility apply; manufacturer coverage is not assumed.

Request a fitment check with your vehicle and part information before ordering, or visit FAQ & Help for ordering and support guidance.
