Re: Information regarding recall FL844 SHM reprogramming
Recall FL844 SHM reprogramming release
The recall will be released onto DTNA Connect on 4/8/2020. I want to thank all of the dealers that reacted quickly to address this issue and get many of these done prior to the official release, due to the importance of this recall. Since we first announced this pending recall, allot of work was still taking place behind the scenes, mainly to identify the cause of the issue. When we first reported this problem to the dealer network, we had over 26,000 buses in the population. We did not know the root cause and โerred on the side of cautionโ. We have since been able to narrow the population down to just over 6,000 buses. The buses in the population that will require the programing were built 1/2/2019 to 2/13/2020.
Important: For units that have already been reprogrammed ahead of the release, using the original lists sent to you, please create a list of those units and provide them to your dealer manager. You will be reimbursed via policy for those units. The campaign will be open to accepting claims for units on the official population list beginning 04/8/2020. Remember that the claim repair date cannot be earlier than 04/8/2020 or the claim will be rejected by the system.
SHM Program
FL844 draft
2/26/2020
Switch Hub Module will need to be programmed with 1.24 software level. To program a SHM you will need the file located on the Thomas Built Dealer Portal under the section Documents/Reporting tools and then Recall Documents and inside the folder labeled downloads.
Once the file is saved to your desktop you will see this icon
- Open the file
- Each time you open the software you will need to set the configure driver
Select Configure driver
You will need to hit select to choose your adaptor tool driver such as Nexiq USB
The tool will show in the first line. Then select override device defaults box and change the rate from 250000 to 500000 and click ok
You are now ready to program a bus
- Connect your diagnostic tool to the 9 pin connector
- Turn ignition to on position, you do not need the engine running to program
- Click read software version to ensure you are connected to the bus and the current level example 1.23 or 1.22 will be displayed to the right of the box
- Click Program 01.24 and the software will initialize and display the status in the programming status area on the screen. If you get an error that programming failed select program button again to restart. Once complete it will show 100% and provide a message the programing was successful
Programing should take less than 1 minute
- Turn the ignition switch off and disconnect your tool from the diagnostic connector. If programing other buses leave the program open and complete process again starting at step 3

Key Talking Points
Introduction: The purpose of this call is to communicate an important customer service development concerning the operation of the electrical system in certain Thomas school buses. Our communication will be specific and at this time we will not be able to elaborate or take any additional questions. We realize that there will be many questions but it is imperative that we follow specific NHTSA guidelines. Please keep this information confidential at this time. We do commit to further communication and will do so at the appropriate times and with the appropriate methods. Thank you for your understanding. Here are the key points of our message:
- Thomas Built Buses will be issuing a recall on school buses with selected warning light packages.
- This will impact approximately 27K C2 school buses.
- This recall is being issued with an abundance of caution, while the failure may never happen, the failure when exhibited is as follows: On the affected school buses the switch hub module (SHM) controlling the exterior warning lights and stop sign may experience a communication issue resulting in deactivation of the red warning lights and stop sign.
- All buses with affected warning packages will receive software updates, a procedure that will take less than 10 minutes.
- The software update is available at this time and instructions will be forthcoming on how you can access it. Each affected dealership will receive an email with their VINs and instructions for downloading the software.
- Buses can continue to operate until the repair is completed. This is the verbiage on the 573 report.
(4)(m) Precaution(s) to be taken Prior to Corrective Measures Implementation: Watch for unexpected change of working system indicator and/or movement of signage and crossing arm. Pressing the momentary activation switch will turn the warning lights back on and deploy the stop sign.
RECALL LETTER INFO
- Registered owners will receive communications per the standard recall methodology
HOLD INFO
- All units ready for pickup at TBB are off hold.
Thatโs what I have to communicate today. I understand that itโs not a pleasant message and I understand that it comes pretty quickly on the heels of another significant one. What I will communicate is that weโll quickly have information to you and it will be our top priority in the coming weeks.
We thank you again for your understanding and ask for your cooperation with our request for confidentiality. We anticipate NHTSA posting the recall data to their website in the immediate future and wanted to make sure you are aware of this prior to hearing from owners. We do understand that there will be many questions and we will address them at the appropriate time. Thank you for your time today.

Defect / Noncompliance Description
For this Defect/Noncompliance:
Describe the defect or noncompliance:
On the affected school buses the switch hub module (SHM) controlling the exterior warning lights and
stop sign may experience a communication issue resulting in deactivation of the red warning lights, stop
sign, and system indicator.
Describe the safety risk:
If the red exterior warning lights stop flashing, and the stop sign retracts, other drivers may be
incorrectly signaled to stop driving before the school bus loading/unloading of students is complete
therefore increasing the risk to injury.
If applicable, identify the manufacture of the defective or noncompliant component.
John Deere Electronic Solutions
Chronology of Defect / Noncompliance Determination
Provide the chronology of events leading up to the defect decision or test data for the
noncompliance decision.:
January 2020, DTNA received a dealer report concerning a specific exterior warning light option package
working intermittently. DTNA began inspecting school buses at the School Bus Plant. The plant inspection
of 25 vehicles revealed four vehicles had exterior warning lights turning off without additional driver
input after operating continuously for an extended period of time. An inspection conducted by the dealer
of 98 school buses revealed 53 school buses reporting a similar issue. February 2020, DTNA received an
additional dealer report of a school bus exhibiting a similar issue manufactured prior to the parameter
update. February 20, 2020 DTNA with an abundance of caution, decided to conduct a voluntary recall
campaign on school buses equipped with the above configuration. February 2020 โ April 2020, DTNA
conducted an in-depth analysis of warranty and test data in conjunction with the SHM supplier. Findings
indicated there were no warranty claims, reports from the field or testing that indicated the issue was
present prior to Jan 2019. April 2020, DTNA amends the 573 defect report to modify the start date of the
recall population to January 2, 2019. No incidents have been reported in the field. Only in unique
circumstances could the issue be replicated.
Identify the Remedy
Describe the defect/noncompliance remedy program, including the manufactureโs plan for
reimbursement.:
The software in the SHM will be updated — Repairs will be performed by Daimler Trucks North America
authorized service facilities. Details of the reimbursement plan will be included in the ownerโs notification
letter.
Identify the Recall Schedule
Describe the recall schedule for notifications.:
Customer notification will be made by first class mail using Daimler Trucks North America records to
determine the customers affected.
