Description
RUNNING Initial display when system test is run; certain “critical” checks are made. Prob-
lems 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.
