When Monitor Mode is enabled, the ignition can be switched off.
If the brake pedal is pressed while Monitor Mode is enabled, Monitor Mode
is temporarily disabled for a preset time and the Auto Start button LED
flashes. If the brake pedal is pressed while Monitor Mode is enabled and the
engine is running, the engine shuts off. Additionally, the Auto Start System
does not function if the engine coolant temperature is too high.
Disabling Monitor Mode - RAM ProMaster Chassis with Auto
Start
To disable Monitor Mode, press and hold the Auto Start button for a preset
amount of time, or press the unlock buttons on the remote control, alternat-
ing between the Front Doors Unlock and Cargo Unlock buttons, a total of (3)
times. If successfully disabled, the Auto Start button LED turns off.
Manual Start Mode - RAM ProMaster Chassis with Auto Start
When Manual Start Mode is activated, the engine starts immediately,
allowing the Volta System to charge, and then shuts off automatically after
the pack voltage reaches a preset high point, when a preset engine timeout
timer expires, or if the fuel level drops below 1/4 tank.
Manual Start Mode is best used to raise the Volta System SOC before leaving
the vehicle short term or going to bed.
To activate Manual Start Mode:
1. Turn on the Volta System.
2. Place the vehicle transmission in park (P).
3. Verify the vehicle’s fuel is above 1/4 tank.
4. Verify the vehicle’s hood is closed and latched.
5. Apply the parking brake.
6. Press the Auto Start button (3) times within (3) seconds.
The engine starts after the third button press.
Troubleshooting and Resetting the Auto Start System after a
Fault - RAM ProMaster Chassis with Auto Start
During normal operation, the Auto Start button LED is on. If the LED is
flashing, the Auto Start System has detected a fault or the brake pedal has
been pressed.
To reset the fault, disable and re-enable Monitor Mode as described pre-
viously, or if the LED is flashing after pressing the brake pedal, wait for the
system timeout to expire, and Monitor Mode automatically re-enables if no
other faults are present.
If the faults persist, refer to the manufacturer documentation for additional
troubleshooting or contact Volta Power Systems.
