(a) Turn engine start and battery
disconnect switches to OFF position
(b) Ride control solenoid valve #3 remains
disconnected from wiring harness.
(c) Disconnect wiring harness
connector(s) from powertrain ECM
(WP 0063 00).
(d) At wiring harness connector for ECM, 1. If each resistance measurement is

wiring harness in question (WP 0195 00
thru WP 0201 00).
3. Check if diagnostic code remains active.
(a) Inspect and clean wiring harness
(b) Reconnect all harness connectors.
(c) Operate machine (TM 5-3805-291-
(d) Check status of CID 2684 FMI 06.
1. If CID 2684 FMI 06 is active, exit this
procedure and repeat this procedure. If
cause of diagnostic code is not found,
replace powertrain ECM (WP 0063 00).
2. If CID 2684 FMI 06 is not active,
problem does not exist at this time.
Resume normal machine operation.
