Always inspect harness connectors that are involved in the
circuit. Poor connections can often be the cause of an electrical
circuit problem. Verify that all connections in circuit are clean and
secure, and connections are in good condition. If a problem with
connection is found, correct the problem and verify diagnostic
code is active before performing this procedure.
Tag wiring harnesses to aid installation.
1. Connect MSD (WP 0016).
Select engine ECM C6.6 D6K
and verify 0174-03 is active.
2. Turn ignition switch to OFF
position (TM 5-2410-240-10).
3. Disconnect filter link harness
