High-Voltage Battery Warnings
There are a number of high-voltage battery cautions and warnings.
The high-voltage battery problem telltale, as shown, see Fig..appears in the dynamic telltale portion of the driver display screen when a non-critical high-voltage battery fault has been detected. A minor issue that takes one of the nine high-voltage batteries offline is an example of a non-critical high-voltage battery fault. This telltale is a signal to take the vehicle in for service.
An amber caution window is also a signal to take the vehicle in for service.
An amber caution that states the driving range has been reduced, as shown, see Fig. for that a program derate has been activated, is a signal that the vehicle should be serviced soon.
A red warning about a high-voltage battery situation, as shown, see Fig..should prompt moving the vehicle off the road to a safe location, turning the keyswitch to the off position, and a call for service.
If a combustible gas detection system LED has illuminated or a high-voltage battery thermal event warning has appeared, exit the cab and call emergency services. For more information, seeChapter 18.
