CORRECTIVE ACTION
3. Place a jumper wire between
the intake manifold pressure +5
volt SUPPLY pin (pin 2) and the
intake manifold pressure
SIGNAL pin (pin 1) at the
engine ECM wiring harness
connector W25 C7 of the engine
ECM wiring harness.
4. Turn keyless engine switch to
the AUX position (TM 5-3895-
385-10), but do not start engine.

screen for fault code SPN#102,
displayed, turn keyless engine
FMI#3.
switch to the OFF position (TM 5-
3895-385-10), and proceed to next
test.
2. If fault code SPN#102, FMI#3 is not
displayed, turn keyless engine

3895-385-10), and replace the
engine harness (WP 0334, Vol 2).
6. Remove the jumper wire
between the intake manifold
pressure +5 volt SUPPLY pin
(pin 2) and the intake manifold
pressure SIGNAL pin (pin 1) at
the engine ECM wiring harness
connector W25 C7 of the engine
ECM wiring harness.
7. Connect engine ECM wiring
harness connector W25 C7 (WP
0451, Vol 3, Figure 45).
8. Turn keyless engine switch to
