Error Code
Fault Description
Troubleshooting Action
Err01
Non fatal control fault
1. Turn key switch off and back on. 2. If error fault returns, go into
the Fault Recall Mode* (Main Control Board Special Program
Options) to further investigate other possible causes. Make
repairs to all electrical system faults found in the fault recall check.
Replace control board only as the last step when troubleshooting.
Err02
Fatal control fault
Same as Err01. Check Fault Recall Mode*. Replace control
board. Follow troubleshooting actions listed for Err01.
Err03
Wheel drive motor overload
1. Check for a tripped drive motor circuit breaker (40 amp).
Investigate reason for possible mechanical over load. Examples:
sticking brakes, parking brake slide lever not released, prolonged
ramp climbing. 2. See Curtis drive motor controller section to
further troubleshoot the drive system (Table 1).
Err04
Lift motor actuator overload
1. Turn key switch off. 2. Wait for display to go off. 3. Check for
binding of burnishing deck linkage or excessive weight on bur-
nishing deck. 4. Turn key on to reset.
Err05
Lift motor actuator severe overload
1. Turn key switch off. 2. Wait for display to go off. 3. Check for
binding or frozen burnishing deck linkage or excessive weight on
deck. 4. Check for short circuit in wiring or actuator motor. 5.
Repair or replace. 6. Turn key on to reset.
Err06
Lift motor actuator open circuit (**)
1. Turn key switch off. 2. Wait for display to go off. 3. Check for
disconnected actuator, open in wiring or defective actuator motor.
4. Repair or replace. 5. Turn key on to reset.
Err07
Pad motor overload
1. Turn key switch off. 2. Wait for display to go off. 3. Check for
binding in rotation of pad or improper actuator operation. 4. Verify
that 8 pin connector on the main board is properly installed. 5.
Check negative supply cable to pad motor for wiring problem or
improper modification (this is a special cable and must be re-
placed with the correct APA part). 6. Turn key on to reset.
Err08
Pad motor severe overload
1. Turn key switch off. 2. Wait for display to go off. 3. Check to
see if pad assembly and pad motor turn freely. 4. Check for short
circuit in pad motor or wiring. 5. Check pad motor, if defective
repair or replace. 6. Verify that 8 pin connector on the main board
is properly installed. 7. Check negative supply cable to pad motor
for wiring problem or improper modification (this is a special cable
and must be replaced with the correct APA part). 8. Turn key on
to reset.

TROUBLESHOOTING GUIDE (AFTER SN 1507058)
Error codes for the main control will be displayed on the hour meter display as they occur. If more than one error exists the display will
sequence through the error codes at one-second intervals. The error display will show on the hour meter as the letters Err followed by
a two-digit code. EX: Err01 would be a non-fatal control fault. Refer to the chart below to determine the fault and the corrective action.
When troubleshooting any “Fault Description” noted with a double asterisk (**) follow the instructions for temporarily disabling
the control boards special fault detection program. See the Main Control Board Special Program Options section in this manual.
