4/4
Flash code 4/4 indicates problems with the battery supply. Not
reported during 2 second power-up.
7
BATTERY LOW
Battery voltage is below 11V for more than 5 seconds. This fault is not
detected during crank. This is a warning – the controller does not shut
down.
BATTERY TOO HIGH – SYS-
TEM SHUT DOWN
Battery voltage is above 16V. EMS recycle required.
BATTERY TOO LOW – SYS-
TEM SHUT DOWN
Battery voltage is below 9V.
5/5
Flash code 5/5 indicates problems with vehicle engine RPM or the
encoder. Not reported during 2 second power-up.
8
SPEED SENSOR READING
INVALID SPEED
This fault is detected with diesel engines only. The RPM pickup is indicat-
ing a speed that greater than 4000 RPM or approximately 8875 Hz.
SPEED INPUT LOST
This fault is detected with diesel engines only. It occurs if there is no RPM
detected and the oil pressure input is reading above 8 PSI for more than
three seconds. This is probably due to wiring problems at the ground mod-
ule or a faulty speed sensor.
6/6
Flash code 6/6 indicates problems with the CAN bus.
10
CAN BUS FAILURE:
The ground module or platform module is not receiving CAN messages.
This is probably due to wiring problems between the platform and ground
modules.
7/7
Flash code 7/7 indicates problems with a motor.
NOT REQUIRED
9/9
Flash code 9/9 indicates problems with the controller.
11
PLATFORM MODULE SOFT-
WARE UPDATE REQUIRED
Platform module code is too old to support the EIM or BPE load sensor and
the machine is configured to use one of these two sensors. The PM code
must be updated to a newer version.
HIGH RESOLUTION A2D FAIL-
URE –INTERRUPT LOST
The ADS1213 chip in the platform module has stopped asserting its inter-
rupt (DRDY) line for some reason. An EMS cycle is required.
HIGH RESOLUTION A2D FAIL-
URE-REINIT LIMIT
The ADS1213 has needed to be reset 3 or more times.
PLATFORM MODULE FAIL-
URE: hwfs CODE 1
Platform module V(Low) FET has failed
GROUND MODULE FAILURE:
hwfs CODE 1
Ground module V(Low) FET has failed
GROUND SENSOR REF
VOLTAGE OUT OF RANGE
These faults occur when the seven volt reference voltage used for the joy-
sticks, sensors, etc. goes out of range. Not reported during 2 second
power-up.
PLATFORM SENSOR REF
VOLTAGE OUT OF RANGE
These faults occur when the seven volt reference voltage used for the joy-
sticks, sensors, etc. goes out of range. Not reported during 2 second
power-up.
EEPROM FAILURE – CHECK
ALL SETTINGS
A critical failure occurred with the EEPROM. Personalities, machine con-
figuration digits, etc. may be reset to default values and should be
checked.
