Troubleshooting Guide 25
Fault during power-up testing
Check if the cables of the park brake are loose or damaged
Park brake short circuit or broken
Check the park brake cables for damage
Notes for Flash Codes 5 & 6:
1 Check to see if the park brake lever is disengaged:
If disengaged, re-engage park brake lever and turn power off and back on to reset
flash code.
2 Check the resistance of the left and right park brakes to determine if the fault is in the
park brake or the controller:
Set your meter to the 200 ohm scale.
Touch the leads together to make sure the ohm meter is accurate. You should have
approximately 0 ohms at this point.
Place the red and black ohm meter leads on the two middle pins of the motor
connector as shown.
The meter should read between 40-80 ohms.
Any reading outside this range represents a bad park brake that should be replaced.
3 If the measurement is within this range, and the controller is still displaying a flash code,
check that the wiring is not damaged and that all cables are connected properly. Make
sure all pins are seated properly in their connectors.
4 If after performing the previous tests and the park brake fault persists, the controller will
need to be returned.
5 If the measurement is within this range, and the controller is still displaying a flash code,
check that the wiring is not damaged and that all cables are connected properly. Make
sure all pins are seated properly in their connectors.
6 If after performing the previous tests and the park brake fault persists, the controller will
need to be returned.
