Section 10: Boost Mode (if Equipped)
Boost Mode allows the vehicle to be started using the lithium-iron batteries to charge the vehicle’s starting
battery/batteries in the event the vehicle requires a jump-start.
•
Boost Mode will allow the lithium-iron batteries to charge the lead-acid starting battery/batteries only if the lead-acid
battery voltage is greater than 7.5VDC.
•
If the lead-acid battery/batteries are lower than 7.5VDC, the vehicle will need to be started through other means.
•
Consult with your vehicle up-fitter on the installation location of the BOOST activation switch or button.
Section 11.1: Communication Error
Section 11: Further System Information
If the Loss of Communication icon appears on the display,
a communication error between the IMS controller and the
vehicle has occurred.
•
In this condition, the engine can only be started and
stopped manually by the operator using the ignition
switch. The shutdown and engagement of Idle Mitigation
Mode will no longer take place while the vehicle is in Park
or Neutral.
•
The vehicle can be driven as if the IMS were not present.
•
The vehicle requires service to check the operation of
the IMS. When this icon is present, contact your fleet
maintenance department immediately to ensure there are
no other defects on the vehicle that may cause the vehicle
to be unsafe to drive.
One of the following codes will appear along with the Loss
of Communication icon:
• CAN1: Communication over the data network that does
not directly involve the vehicle.
• CAN2: Communication between the IMS controller and the
chassis.
