3. Check if diagnostic code remains active.
(a) Inspect and clean wiring harness
(b) Reconnect all wiring harness
(c) Operate machine (TM 5-3805-291-

procedure and repeat this procedure. If
cause of diagnostic code is not found,
replace powertrain ECM (WP 0063 00).
2. If CID 2684 FMI 03 is not active,
problem does not exist at this time.
Resume normal machine operation.
