CONTROL MODULE
Check
The control module converts analog signals from
the control handle to digital signals for the control-
ler to read. If the controller is reporting an input
error fault code, then the control module may be
malfunctioning. Check the control module using the
following steps.
1.
Remove drive unit compartment covers for ac-
cess to the electrical components, and raise the
drive tire off the floor to prevent unexpected
movement. See the section Periodic Mainte-
nance 8000SRM1635.

Connect the battery and turn the key switch to
the ON position. Make sure the parking brake
switch is in the OFF position.
3.
Connect the negative voltmeter lead to the neg-
ative battery cable connection at the controller.

Disconnect 6way connector B, check pin 3 (on
the harness side) for +24V. See Figure 7.
