M-10 ACE

Overview

The M-10 ACE system allows the rider to adjust the M-10 rear
suspension FRA position electronically by pushing the Mode /
Firm or Set / Soft Switch on the left handlebar control.

The ACE system consists of the following components:

• Mode / Firm - Set / Soft Switch - Used in conjunction 

with the ACE / Gauge console rocker switch. In the 
ACE mode, pushing the switch up is for a firmer 
setting, while pushing the switch down is for a softer 
setting. In the Gauge mode, the switch controls the 
MFD display settings.

• (A)CE / (G)auge Console Rocker Switch - The switch 

allows the rider to control either the MFD gauge 
settings or the ACE controller. In the ACE position, the 
ACE Controller will move the FRA and signal the 
FRA’s position to the MFD gauge. In the Gauge 
position, the ACE controller will pass the Mode/Set 
signals to the MFD gauge.

• Ace Controller - Located behind the left foot rest, this 

controller reads the position of the ACE / Gauge Rocker 
Switch, position of the Mode/Firm - Set/Soft Switch, 
and the actuator motor potentiometer position. If will 
also output actuator motor forward and reverse drive 
power, ride position signal to the MFD gauge, and 
protect the ACE system from short circuits and power 
surges.

• The controller reads the position of the potentiometer 

and supplies a signal to the gauge. Full soft is 0 volts, 
full firm is around 5.5 volts. The entire system will 
function without a gauge, but if the gauge is 
operational, most likely the potentiometer is also good

• Actuator Motor - Drives the ram that moves the FRA.

• Potentiometer - Used to signal the position of the FRA 

ram. When the ram is fully retracted, the resistance is 
120 ohms. When fully extended, the resistance is 650 
ohms.

Checking Components

When checking the function of all the ACE components, use the
supplied service tool part number PA-46355. The power supply

must be able to supply at least 13.1 volts and 5 amps (as most
battery chargers WILL NOT WORK). 

Connect the tool to the CHASSIS DIAGNOSTIC POWER
SUPPLY PLUG.

ITEM

CHECK

ACE MOTOR

Disconnect the BLUE and GREEN
wires from the controller and apply 12 volts across these wires. The motor should move
either in or out. Change the polarity and the direction should change. If the motor does
not move, check wire continuity to the motor. If continuity is good, replace motor.

POTENTIOMETER

Check basic resistances: 1000 ohms between BLACK and ORANGE.
Fully Retracted (Firm Setting): 120 ohms between BLACK and WHITE.
Fully Extended (Soft Setting): 650 ohms between BLACK and WHITE.
If these resistances are not to spec and/or they do not change as the motor moves, replace the 
potentiometer.

LEFT HAND SWITCH

Continuity between BROWN and the WHITE/GREEN when the switch is depressed in the firm 
direction. The same is true for the GREEN/WHITE when depressed in the soft direction. 
Replace the switch if otherwise.

CONTROLLER

All the following must be true or the controller must be replaced.
a. With the system powered up using the jumper, measure the voltage across the BLUE and
GREEN wires (motor wires). A voltage of -13 to 13 volts should be present when the
switch is depressed.
b. A voltage of 0--6 volts should be measured between the ORANGE and BROWN gauge
wires when the system is powered. This voltage should change accordingly when the
system is adjusted (near 6 volts at firm, near 0 volts at soft).
c. 5 volts +/- 1 should be measured between the ORANGE and BLACK module leads when
the system is powered.
