(7) Mounting flange on the ITSM
Remove four nuts (4) and washers (6) from mounting flanges (7) of the ITSM. Ground strap (5) must also be lifted from one of the studs.
Remove the ITSM from the engine.
Install the replacement ITSM. Orient the 54-pin connector toward the bottom of the engine.
Use the mounting hardware to install the new ITSM. Be sure to install ground strap (5) between one of the washers on the mounting flange and the nut. Note: One of the washers is a lock washer. Be sure to install the lock washer between ground strap (5) and mounting flange (7). The lock washer improves the electrical conductivity between the ground strap and the mounting flange.Check the mounting hardware and the ITSM for correct installation. A properly installed ITSM will move slightly on the rubber grommets. If the ITSM cannot move slightly on the grommets, check that the mounting hardware is installed correctly.
Connect connectors (2) and (3) to the ITSM.
Program the configuration parameters and the monitoring system parameters into the replacement ITSM.
