CORRECTIVE ACTION
8. Turn BATTERY DISCONNECT
switch to ON position (TM 5-
3895-385-10).
9. Start BMPM engine (TM 5-
3895-385-10) and let it idle for 1
minute.
10.Check active engine faults
1. If fault code SPN#102, FMI#3 is
screen for fault code SPN#102,
displayed, turn keyless engine
FMI#3.
switch to the OFF position (TM 5-
3895-385-10), and replace engine
ECM wiring harness (WP 0334, Vol
2).
2. If fault code SPN#102, FMI#3 is not
displayed, turn keyless engine
switch to the OFF position (TM 5-
3895-385-10). No fault present;
restore equipment to original
condition.
4. Engine ECM fault.
1. Disconnect engine ECM wiring

engine ECM (WP 0451, Vol 3,
Figure 45).
2. Turn keyless engine switch to
the AUX position (TM 5-3895-
385-10), but do not start engine.
3. Measure voltage with multimeter
1. If supply voltage is between 4.75
at engine ECM +5 volt SUPPLY
and 5.25 VDC, turn keyless engine
pin (pin 37) to intake manifold
switch to the OFF position (TM 5-
pressure RETURN pin (pin 47)

2. If supply voltage is not between
4.75 and 5.25 VDC, turn keyless
engine switch to the OFF position
(TM 5-3895-385-10), and replace
engine ECM (WP 0332, Vol 2).
