Description
RUNNING Initial display when system test is run; certain “critical” checks are made. Problems that can be
reported include below messages.
ONLY 1 ANALYZER! Do not connect two Analyzers while running the system test.
BATTERY TOO LOW The system test cannot run with battery voltage below minimum (9 V).
BATTERY TOO HIGH The system test cannot run with battery voltage above maximum. (16 V).
CHECK CAN WIRING The system test cannot run in platform mode unless data is being received from the platform and
ground modules. The system test cannot run in ground mode unless data is being received from
the platform module.
CHECK SPEED There is an open- or short- circuit in the speed encoder wiring. Check speed encoder.
BAD GROUND MODULE An internal problem was detected in the ground module.
HIGH TILT ANGLE The vehicle is very tilted (19.3°), or the tilt sensor has been damaged. Check tilt sensor.
HOT ENGINE The engine temperature exceeds 100 °C. This is only a warning.
BAD I/O PORTS The controller detected a problem with its internal circuits at switch on. If other problems are also
detected, the controller may need replacing.
SUSPECT EEPROM The controller detected a problem with its EEPROM stored personality settings at switch on.
Check and, if necessary correct, all personality settings.
OPEN FSW In platform mode, the footswitch must be open at the start of the test.
CLOSE FSW In platform mode, the footswitch must be closed when this message is displayed; the footswitch
MUST BE KEPT CLOSED during the valve & contactor tests.
BAD FSW The two footswitch signals are not changing together, probably because one is open-circuit. One
footswitch signal (“FSW1”) is routed to the power module, the other (“FSW2”) is routed to the
platform module. Check footswitch and wiring.
