Error/Fault Description
Correction
01
Scrub deck sense R2 resistor fault
A fault will occur if scrub deck sensor resistor is
unplugged or damaged. Check the resistor wiring for an
open and substitute a new resistor and test scrub deck
for correct operation. Note that there are four different
resistor values used on the different deck types. See the
electrical diagram decal for the correct specification for
the resistor to replace.
03
Speed control fault
Observe the blue flashing light detergent indicator light,
then refer to the
Wheel Drive, Traction
section to
troubleshoot the drive system.
04
Scrub motor overload
Note that some models use one, two
or three scrub motors. Refer to the
Specifications
section for detailed
load current values for the different
decks.
1. Check for binding in the rotation of the brushes and
incorrect brush deck lift actuator operation.
2. Check the negative supply cable at the brush motor
for a wiring problem, and also the small BRN current
sense wire in the harness and A2 pin J2-2.
3. Check for a short circuit* in the brush motor or wiring.
On cylindrical models check for excessive belt tension
and the condition of the idler bearing.
