Service Bulletin
Description of Revisions:This bulletin replaces the version dated
August 2014. Software version numbers are revised in Table 1,
and software update 6.3 is added.
General Information
Cascadia Cabin CAN electronic control units (ECUs) must have compatible software. See Table 1 for the compatibility cross reference. A software level mismatch in the Cabin CAN ECUs may lead to undesired and unpredictable vehicle behavior. Use the instructions in this bulletin to bring all Cabin CAN ECUs to compatible levels
of software. Affected ECUs include the following:
• SAM Cab
• SAM Chassis
• Modular Switch Field (MSF)
• Central Gateway (CGW)
When a vehicle is in service it is possible for one or more of these ECUs to be replaced or programmed with a
software level that is not compatible with the others.
ServiceLink checks Cabin CAN ECU compatibility using the following indicators:
• A pop-up dialog box appears if an incompatible software version is detected on the vehicle. See Fig. 1.
• A row on the "Problem ECUs" list indicating an incompatibility exists. The "Incompatible" row remains
present until all Cabin CAN ECUs are compatible. To view the problem ECU list, click on the "List" icon
from the "General Info" ServiceLink screen. See Fig. 2.
NOTE: This bulletin shows compatibility of the ECU software versions only. To identify compatible
ECU hardware, see Service Bulletin 54-231, Replacing SAM Cab and SAM Chassis Hardware
Assemblies.
Downgrading ECUs to older software versions to obtain compatibility is not recommended. Whenever software
is upgraded, always flash software before flashing parameters. When software is flashed, ServiceLink will also
migrate and then flash the parameters to complete the upgrade.
Compatible Sets of Cabin CAN ECU Software
The software versions of the four Cascadia CAN ECUs must be compatible. The software in all four ECUs must
all be coordinated to one of the release versions shown in Table 1. For the electronics to operate properly, use
ServiceLink to check and flash any ECU with the software that will make it compatible with the others for the
appropriate release.
NOTE: In most instances there is more than one compatible software version that an ECU could have
for a release.
Combining SAM Versions 5.4 and 6.2
A SAM version 6.2 may be used in a 5.4 vehicle without the need to upgrade the other electronics in the
system. If the vehicle is at a lower level than 5.4 release, the Cabin CAN ECUs must first be flashed up to version 5.4. ServiceLink will prompt to allow the latest versions of the 5.4 software suite that is compatible for the
vehicle hardware.
When a SAM 6.2 is used on a 5.4 vehicle, ServiceLink is then required to upgrade the host software information
and parameters for the new SAM 6.2.

When the SAM 6.2 is installed, connect ServiceLink and select whichever new SAM (cab or chassis) that was
just installed. Click on the "Flashing" tab and select the latest available version of software, then flash the vehicle with this software.
This process permanently upgrades the host and vehicle information for the SAM to release 6.2.
Attempting to Combine SAM Versions 6.0 and 6.2
A SAM version 6.2 may not be used in a 6.0 vehicle unless the other SAM with release 6.0 is flashed up to release 6.2.
ServiceLink will prompt to allow the latest available versions of software compatible for the vehicle hardware,
which is the 6.2 release. DO NOT select the latest available version of software unless it is intended to upgrade
the vehicle to 6.2. Use the 6.0 software version identified in table 1 to keep the SAMs at 6.0.
When a SAM 6.2 will be used on a 6.0 vehicle, ServiceLink is then required to upgrade the host software information and parameters for both, the new SAM 6.2 and the remaining SAM 6.0.
After replacing the SAM, connect ServiceLink and select whichever new SAM (cab or chassis) that is installed.
Click on the "Flashing" tab and select the latest available version of software, then flash the vehicle with this
software. Repeat this step for the other SAM.
This process permanently upgrades the host and vehicle information for the SAMs to release 6.2.
IMPORTANT: When the Central Gateway is updated to the most recent software on EPA07 vehicles,
the J1587/J1708 wires must be disconnected from the CGW. The updated CGW does not have the
capability of rerouting CAN ECU faults on J1587/J1708. Removing the J1587/J1708 wires from the
new CGW does not affect any function of the CGW. However, since EPA07 vehicles use J1587/J1708
for generic CAN ECU faults that were rerouted by the original CGW for display on the ICU, these
messages will not be present.
