7.20.4 Removing and Installing the Controller
Two different replacement controllers are available:
1. Re−manufactured − Controller is the equivalent
of a new OEM controller and is supplied with a
12 month warranty.
2. Repaired − Controller has had previous faults
repaired and upgraded with the latest software.
Repaired controllers are NOT to be used for
warranty repairs. Only full OEM re−manufac-
tured controllers are to be used.
Replacement controllers will be factory equipped with
the latest version of operational software, but will NOT
be configured for a specific model number and will
need to be configured at the time of installation or sale.
a. Removal:
1. Disconnect all front wire harness connectors
and move wiring out of way.
2. The lower controller mounting is slotted. Loosen
the top mounting screw (see

3. Disconnect the two back connectors (EC) and
remove module.
4. When removing the replacement controller from its
packaging, note how it is packaged. When return-
ing the old controller for service, place it in the
packaging in the same manner as the replacement.
The packaging has been designed to protect the
controller from both physical and electrostatic dis-
charge damage during storage and transit.
b. Installation:
Install the module by reversing the removal steps.
Torque values for mounting screws (item 2, see
