6.20.4 Removing and Installing a Module
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--19) and lift up and
out.
3. Disconnect the back connectors and remove mod-
ule.
4. When removing the replacement module from its
packaging , note how it is packaged. When returning
the old module for service, place it in the packaging
in the same manner as the replacement. The pack-
aging has been designed to protect the module from
both physical and electrostatic discharge damage
during storage and transit.
b.Installation:
Install the module by reversing the removal steps.
Torque values for mounting screws (item 2, see
Figure 6--19) are 0.23 mkg (20 inch-pounds). Torque
value for the connectors is 0.12 mkg (10 inch-pounds).
