Auto & Heavy Duty Computer Supply is one of the most reputable names in auto and heavy duty Electronic Control Module (ECM) repair and supply. We have been in the forefront of this specialized market since 1997.
The ECM is the power control module for heavy duty engines and or power control module for your trucking industry tractor engines and heavy machinery electronic controllers. The Heavy Duty ECM is the engine or powertrain management system, fuel management system and diagnostic management system which are all vital to production and commerce. We have been rebuilding ECM's since 1997. We offer testing and repair service and can supply many models remanufactured and programmed to features and parameters in advance for inventory sale for minimum lost production time.
Our automotive ECM division began research and development on heavy duty ECMs in 1999 due to the high demand and high failure of Cummins, CAT, Detroit D-DEC, V-Mack, Allison and several other manufacturers. We understand that heavy duty transportation rigs and mechanical equipment is vital to the running of a business big and small and even vital to the running of basic commerce. Even more so we understand that without your delivery services operating, you are not only losing money, it may even cost you many more dollars in production, leasing fees or lost jobs and revenue. Presently when you are faced with a bad ECM your only options are purchasing a new unit from the manufacturer which can cost from $2,500-$5,000 US to using a “pullout” or used ECM which is unlikely to be still in working order and would have to be reconditioned and coded with the features and parameters of the tractor truck or rig. This used unit option does not give you specific data to help your service department locate a problem that has adversely affected the ECM and may likely repeat the damage.
We have found that many models of the engine and transmission and other electronic controllers for heavy duty trucks and heavy duty machinery, often called ECMs, are exposed to many factors that damage the internal electronics of the ECM. Factors adversely affecting the electronic controllers are normal operation such as powering up or down, engine idle sensors, failed injector(s) in diesel engine, fuel solenoid operation, and even lightning strikes. Also due to the location of many of the ECM units, often they are mounted to the engine and exposed to the environment; simple maintenance operations such as power washing the rig can be detrimental to the ECM and the wiring harness.
We have researched and confirmed many model ECMs fail after 3 to 5 years of use due to the failure of internal components on your ECM simply failing due to electrical spikes and the aforementioned events. These components must be replaced in all remanufactured ECMs in order for your computer controller board to function properly. We offer an ECM testing service on-rig for many makes and models. Your ECM could also have taken an electrical hit from a bad injector(s), the engine idle sensor or fuel solenoid, and/or a compromised actuator harness. We can instruct you on which components may have damaged the ECM when we test the ECM on site at our facility. By looking at the damage on the ECM motherboards, often we can detect specific vital information to ensure you do not damage another expensive replacement ECM computer. After the ECM repair is complete, memory features and parameters are restored to the ECM. We reprogram your ECM to your engines specifications including your Control Parts Listing CPL, governor settings, rpm settings, Jake brake, cruise control, tire size, rear axle ratio and more.
All our units include a 1-Year unlimited mileage warranty. We include a warranty checklist which accompanies all outgoing repaired and programmed ECM units to finalize the repair of the truck before ECM installation. ECM's and electronic controllers now have many different applications and many are programmable. The features and parameters are coded into the ECM by the manufacturer and we are an authorized programmer for most heavy duty mfd ECM's and electronic controllers. The features and parameters are often referred to as a CPL or Control Parts List number which we can apply to each outgoing unit and test via our advanced testing equipment including our Nexiq Pro-LINK scanning equipment. We offer many models that can be purchased in advance that are remanufactured with upgraded components and we can program the ECM to your rig in advance. Or take advantage of our experienced technical team in a support role. We only ask for the opportunity to service your heavy duty trucks and equipment. Our main goal is to supply quality service and products at an affordable price. |
