Table 15-7 QEC Error Messages, QEC 3 (Firmware 2.X.X)
Fault Code Description Possible Causes
11002 Engine at lowest stroke
command and halls still at limit
ADC calibration not done,
engine measurements are
wrong, burner issue, engine
hardware issue.
11003 Positive bus voltage greater
than limit
Battery is bad, brake is not
working, ADC calibration not
done
11004 Negative bus voltage greater
than limit
Battery is bad, brake is not
working, ADC calibration not
done
11005 Hall watchdog timer has
expired
Load drop, noise, QEC
hardware failure
11006 No hall pulses measured Hall signals not connected, hall
sensor failure
11007 Brake current greater than
hardware limit
QEC hardware failure
11501 Engine frequency is above or
below expected value
Hall calibration is wrong, noise,
incorrect engine pressure
11502 Incorrect hall readings at rest
position
Hall signals not connected, hall
sensor failure
Check engine connector - Hall
pins are the 4 pins above the
power pins, pin 1 is left most
pin when looking at the pins.
Multimeter in diode check, red
lead on pin 3, black lead on pin
1, should read ~0.6V, black lead
on pin 2, should read ~0.6V.
Black lead on pin 3, red lead on
pin 4, should read ~1.8V.
Multimeter in resistance
mode, black lead on pin 3, red
lead on pin 1, 2 and then 4,
each measurement should be
open or Megaohms.
11503 Piston bias measures above
limit for XX cycles
Hall calibration is wrong,
engine is high bias
11504 Hall goodness of fit below limit
for XX cycles
Hall calibration is wrong, noise
