Virtual Technician is the integrated remote diagnostic system for Freightliner trucks equipped with Detroit engines. With Virtual Technician, fleets and owner-operators know within minutes when their engine or after treatment system experiences a fault event, the severity of the fault and when, where and how to best fix the issue causing the fault. Severe fault events are further analyzed by Detroit Customer Support Center (CSC) experts. Complete fault event details are viewable via the Detroit Connect portal.

Detroit Connect Analytics provide users with on-demand, automated analysis and reports with key insights developed by DTNA and Detroit experts. Analytics uses that expertise to quickly identify behaviors, trends, root causes and key insights on fuel consumption and safety performance data across the fleet. This allows fleets to spend less time crunching data and more time optimizing vehicle performance.

Detroit Connect Direct provides fleets with direct access to critical information such as vehicle location, fault codes and diagnostics, fuel performance, safety data and driver behavior. With Detroit Connect Direct, customers can select which data sets they want, how much and how frequently they would like that data made available, so it can be imported into their backend systems. Detroit Connect Direct is delivered through the proprietary Detroit Connect platform exclusive to the new Freightliner Cascadia.

The proprietary Detroit Connect platform, exclusive to the Cascadia, will link wirelessly with an in-cab device via Bluetooth, which allows hours of service (HOS) data to be delivered to Detroit Connect authorized Electronic Logging Device (ELD) apps. This provides the necessary information required from the vehicle to meet the federal ELD regulations without the need for any additional pieces of hardware.

In some cases, and in some engine models you can actually clear certain active codes. For instance, certain Volvo and Mack trucks will display active codes on the dashboard but when you plug in the diagnostic software the fault codes display as inactive. However, you must always take caution to check to see if you have an actual active fault code or an inactive fault code.

The inactive fault codes were once active at some point in time but now they are fixed, or they fixed themselves. The ECU goes through a verification check to see if the fault code has been fixed or not at each time the truck is powered on. Essentially, this is an internal self-test to ensure that the fault codes are or are not an existing problem.

We just had a call the other day with a customer who owns a 2019 Freightliner chassis with Cummins 6.7 ISB passenger bus. This customer was in a derate condition with active SCR inducement derate (5mph) fault codes. The Freightliner was taken into a dealer where ECU was reprogrammed in order to clear the active fault codes. However, after he left the dealer and approximately 150 miles later the Freightliner went back into an SCR inducement derate a.k.a. 5mph derate. It can be difficult to get down to the root cause of certain active fault codes, but it is imperative that you figure out what caused the fault code to occur in the first place to prevent the same issue from occurring again. There is a reason why this Freightliner chassis went into a derate again and knowing that would have ensured that the real problem was fixed.

You can use OTR Diagnostics to read your fault codes that appear on your vehicle directly on your mobile device. You'll be able to see enhanced fault code details, a description of your fault code, troubleshooting steps, fault symptoms, repair procedures, and the number of times a fault code has appeared.

Having the correct information about the fault codes can ensure that you will fix the right part the first time. Diagnosing a fault code takes time and patience. Especially if you are a technician or shop owner, it's important to have good spare parts to test on. Using good parts will validate the proper repair was performed. For instance, don't replace your engine ECU until it's checked it with another spare engine ECU to make sure that is indeed is the root problem.

A fleet of 500 vehicles can see upwards of 200 fault codes (also known as SPN error codes) go off per day. That is over 1,400 codes in a week that a fleet manager has to manually review for severity and close out. Not only is it time consuming to read and close out fault codes but the manual effort can often result in missed critical alerts, leading to expensive on-the-road breakdowns.

Of the 18 million fault codes, SPN 1761 triggered the most out of the minor codes, popping up 144,727 times. DEF became a major need for medium and heavy-duty Diesel vehicles to help reduce their pollution output as regulation became tighter around federal emission guidelines.

You will see SPN 639 pop-up when communication has been lost between the engine control module (ECM) and another device via the SAE J1939 data link. The check engine light will illuminate, and the ECM immediately logs the fault code. To validate the repair, perform a key cycle, start the engine and let it idle for 1 minute. Fortunately, there is no effect on vehicle performance.

You may notice SPN 520256 fault code pop-up when your window regulator motors stop working correctly. This is because the motors in window regulators are not intended to run continuously, as there is a thermal cutoff. However, if they run long enough, or if they get too hot, the motors will be temporarily disabled to prevent damage and a fault code will trigger.

Simple Fix: The issue is resolved by cycling the ignition switch, which resets the modules. If the problem persists even after shorter periods of operation, the window regulator motor may be damaged and must be replaced.

SPN 520289 showed up nearly 10,000 times which is quite remarkable given that this code is very weather dependent and not all Pitstop customers are in cold climates! Of course, this fault code is as the name describes. There are heaters on mirrors to prevent fogging, and is entirely dependent on the weather.

SPN 1231 fault code may pop up when the Motor Control Module (MCM) stops receiving messages from the Aftertreatment Control Module (ACM) for 5 seconds. This may be caused by an over or under-voltage supply to the ACM module or a fault set during a reprogramming event. If you want to conduct a preliminary diagnostic (not necessary), plug in a diagnostic device to the 9-pin connector, switch off the ignition, then unplug the USB cable from the 9-pin connector. Reconnect the USB link after waiting five minutes. Recheck the fault code after turning on the ignition.

Lack of ignition supply to the Model Predictive Control (MPC) often results in the SPN 524127, which stops the MPC from communicating. As a result, you may notice you are not receiving any reflected radar signals over a long period of time. An obstructed radar view can also cause this. If you are using cooperative adaptive cruise control and platooning, this issue can impact your fleet more by reducing the potential for cooperation and improving traffic flow.

Simple Fix: Check for any obstructions to the radar, then clear the code and let the ignition run for a minute. If the fault code pops up again, relay this information to your technician to check during your next PM visit.

Vehicle control modules or sensors monitor system voltage to ensure it is within the normal operating range. For example, when the ignition is turned on, the Diagnostic Trouble Code (DTC) is set when the control module or sensor detects a system voltage of fewer than 9 Volts for 5 seconds, causing SPN U3001 to set off. This can happen for several possible causes, such as a faulty control module setting the code, the control module harness being open/shorted, or if there is a poor electrical connection.

The customer had some other codes that were active previously, and had already fixed the problem. However, the truck was still derated with the codes mentioned above and he wasn't sure how to fix it. The procedure:

Thank you, Tyler. Those two codes have turned a lot of my hairs grey! Where did you find that procedure? Here is something I posted in another forum a while back... just in case that doesn't work for someone.

"I went to a shop last week to look at this truck, two codes were in the PCM and would not clear. The shop diagnosed the truck with a bad particulate sensor. The sensor was replaced and the code did not come back. The 3712 and 3714 codes however would not clear, and the engine was in derate mode. Below you can see the conditions for clearing the code:

Conditions for Clearing the Fault Code: This fault code will go inactive once all other active fault codes have been addressed. Refer to the appropriate fault code troubleshooting tree. The ECM will turn off the red STOP ENGINE lamp immediately after the diagnostic runs and passes.
