If you have one or more John Deere equipment in your fleet, you need the Jaltest John Deere engine code reader to track and monitor their health and ensure that they are always on the job without downtime.

The John Deere Engine Fault Codes List And How Does It Work 

It is now required by law for every modern vehicle or equipment to have an onboard computer to know about their state on various metrics. These include hydraulics, brake lights, body computers, transmissions, and most importantly, engines. When a malfunction occurs, it is shown as a fault code, typically in alpha-numeric form, on the display panel of the onboard computer tucked away below the dashboard on the driver’s side.

Based on the identification of the code and the corresponding problem, resolutions can be initiated to bring the equipment back on the job. This is done with our Jaltest John Deere trouble codes reader and software which needs to be connected to the onboard computer. Backed by live technical and maintenance data, you can resolve the issues at a level that is no less than the dealer level.

Now, what are trouble codes also known as John Deere flash codes?

These codes are displayed on the onboard computer as a flashing light sequence indicating a fault within the systems or components of the machine or equipment. When you connect the Jaltest John Deere engine code reader to the onboard computer, the John Deere flash codes will be reflected on the software laptop too. From here, you will be guided on the most optimized solutions to bring your equipment back on the job.

Take the example of John Deere excavator trouble codes. As with other types of John Deere equipment, these codes are of two types.

One is the temporary Diagnostic Trouble Code (DTC) or flash code that requires simple solutions and generally is cleared within a few driving cycles before a minor issue becomes a full-blown problem.

The other type is more permanent in nature and needs complex resolutions to clear. An example is Flash Code ECU 001008.18 which indicates low oil pressure related to the engine control unit. Another example is soot accumulation in the diesel particulate filter of diesel engines.

A quick word about John Deere SPN code is relevant in this context. SPN is short for Suspect Parameter Numbers and represents fault codes that indicate that something is wrong with the vehicle or equipment. SPN codes specify the type of vehicle and where it was issued, provide important information about specific malfunctions, and help to quickly and seamlessly resolve issues with the equipment.

An example of John Deere SPN codes is SPN 157 which informs that fuel pressure is low or rail pressure sensor voltage is out of range. SPN codes are applicable only in John Deere equipment that uses a J1939 CAN data link.

In every instance, our Jaltest John Deere engine live monitoring tool will guide and handhold you through the most optimized solutions so that your equipment is back on the job at the earliest.

The John Deere engine parameter setting is done by connecting the Jaltest John Deere engine fault codes list software to the onboard computer of the equipment and adjusting engine parameters. You need to access the software and navigate to the “engine” option in the menu. Now set the various engine parameters that will optimize the performance of the equipment from the drop-down menu.

John Deere Trouble Codes And Forced Regens

Forced regen is one of the most critical activities on the John Deere engine fault codes list and a complex one too. Forced regens become essential when there is soot buildup in the diesel particulate filter of a diesel-powered engine and passive regens are unable to clear the soot. Depending on the severity of the soot accumulation, it is not uncommon for equipment to seize up and go into limp mode.

When such a trouble code shows up on the Jaltest John Deere engine code reader, the software will take steps to clear the soot through forced regens. Typically, it means running the engine for around 40 minutes at a rev as specified in the software ranging from High to Very High based on the extent of soot accumulation.

The rise in temperature of the exhaust gas due to the constant running at a high rev burns off the collected soot in the diesel particulate filter and frees up the engine. This fault happens in diesel-powered engines that have stop-go-stop driving cycles like dozers and excavators and not long-haul buses and trucks that run for extended periods.
