Described Condition

In eCascadia and eM2 vehicles, the active fault codes by eDrive common powertrain controller (ECPC) and
unified diagnostic services (UDS) are generally reliable and should not be ignored. Troubleshoot beginning with
the lowest number SPN then progressively work through faults with increasing numbered SPN's. Fault codes
under the J1939 in DiagnosticLink® can be ignored. The purpose of this service bulletin is to provide guidance in
avoiding unnecessary actions in response to those active fault code triggers that, despite being triggered, do not
require any intervention.

The fault codes listed in the Table 1 and 2 result when the Estop button is pressed. No troubleshooting is
necessary with these fault codes until the Estop button is released and the vehicle has been powered down, then
repowered. The fault codes listed in Table 3 should generally be ignored. As future software updates are
programmed into the vehicles, these fault codes are expected to be eliminated.
