CHECK CAN WIRING
The system test cannot run unless the CAN Bus is operating properly
BATTERY VOLTAGE TOO LOW
The system test cannot run with MTM-reported battery voltage below 39.5V (not UGM-compen-
sated value)
BATTERY VOLTAGE TOO HIGH
The system test cannot run with the MTM-reported battery voltage above 65V
CHECK SPEED
Reported vehicle speed must = 0 Hz (or mph)
HIGH TILT ANGLE
The vehicle is tilted > 3° or the tilt sensor if faulty
OPEN FOOTSWITCH
In platform mode, the footswitch must be open at the start of the test.
CLOSE FOOTSWITCH
In platform mode, the operator must close the footswitch when this message is displayed
BAD FOOTSWITCH
The two footswitch signals are not changing together, probably because one is open circuit. Check
footswitch and wiring.
OPEN FOOTSWITCH
In platform mode, the operator must open the footswitch when this message is displayed.
PLATFORM OVERLOADED
Load Sensing is configured and the ground module considers the platform to be overloaded
