6.23.4 Removing and Installing the Controller
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 Figure 6-25) and lift up and
out.
3 Disconnect the two back connectors (EC) and re-
move module.
4 When removing the replacement controller from its
packaging, note how it is packaged. When returning
the old controller for service, place it in the packaging
in the same manner as the replacement. The pack-
aging has been designed to protect the controller
from both physical and electrostatic discharge dam-
age during storage and transit.
b. Installation:
Install the module by reversing the removal steps.
Torque values for mounting screws (item 2, see
Figure 6-25) are 0.23mkg (20 inch-pounds). Torque
value for the connectors is 0.12mkg (10 inch-pounds).
