3.2 DID
DISPLAY
In the DID you will find the percentage of trip
made with regenerated electricity displayed
along with the instantaneous fuel consumption.
This value is reset each time the engine is
restarted
FIGURE 23: PRIME DID DISPLAY
In addition to the standard voltage gage, the DID
also includes a state of charge gage for the
batteries:
FIGURE 24: BATTERY STATE OF CHARGE
This gage displays the level of charge for the
12v and 24v battery banks in percentage.

ELECTRICAL SYSTEM DIAGNOSTIC
Using the driver information display (Figure 25),
check if there are active errors in the vehicle
electrical system. With the
diagnostics
menu,
highlight
fault diagnostics
and then highlight
electrical system
to request a diagnostic of the
electrical system from the mcm. Press the enter
key. If applicable, the DID shows the multiplex
device id, the fault messages or fault codes
recorded. When more than one fault is recorded,
