Power Derate 2
The actuator is limited to a maximum opening of
20%. If “Power Derate 2” is active, it will remain
active until the active DTC goes away and the
ignition input to the GCP (usually the ignition
switch) is cycled.
 DTC 2115: FPP1 higher than IVS limit.
 DTC 2139: FPP1 lower than IVS limit.
 DTC 2116: FPP2 higher than IVS limit.
 DTC 2140: FPP2 lower than IVS limit.
 DTC 2126: FPP1 higher than FPP2.
 DTC 2121: FPP1 lower than FPP2.
 DTC 1171: MegaJector delivery
pressure higher than expected.
 DTC 1172: MegaJector delivery
pressure lower than expected.
 DTC 1173: MegaJector communication
lost.
 DTC 1176: MegaJector internal actuator
fault detection.
 DTC 1177: MegaJector internal circuitry
fault detection.
 DTC 1178 MegaJector internal
communication fault detection.
 DTC 606: COP failure (Internal GCP
failure).
 DTC 1612: RTI 1 loss (internal GCP
failure).
 DTC 1613: RTI 2 loss (internal GCP
failure).
 DTC 1614: RTI 3 loss (internal GCP
failure).
 DTC 1615: A/D loss (internal GCP
failure).
 DTC 1616: Invalid interrupt (internal
GCP failure).
 DTC 601: Flash checksum invalid
(internal GCP failure).
 DTC 604: RAM failure (internal GCP
failure).
Fault Low Rev Limit
The engine RPM will be limited to a maximum of
1600 RPM. If the “Fault Low Rev Limit” is active,
it will remain active until the active DTC goes
away and the ignition input to the GCP (usually
the ignition switch) is cycled.
 DTC 2122: FPP1 high voltage.
 DTC 2123: FPP1 low voltage.
 DTC 2115: FPP1 higher than IVS limit.
 DTC 2139: FPP1 lower than IVS limit.
 DTC 2116: FPP2 higher than IVS limit.
 DTC 2140: FPP2 lower than IVS limit.
 DTC 2126: FPP1 higher than FPP2.
 DTC 2121: FPP1 lower than FPP2.
 DTC 1531: IVS/Brake interlock failure.
Force to Idle
The engine RPM will be limited to a maximum of
800 RPM. If the “Force to Idle” is active, it will
remain active until the active DTC goes away.
 DTC 2122: FPP1 high voltage.
 DTC 2123: FPP1 low voltage.
 DTC 2128: FPP2 high voltage.
 DTC 2127: FPP2 low voltage.

DTC 2115: FPP1 higher than IVS limit.

DTC 2139: FPP1 lower than IVS limit.
 DTC 2116: FPP2 higher than IVS limit.
 DTC 2140: FPP2 lower than IVS limit.
 DTC 2126: FPP1 higher than FPP2.
 DTC 2121: FPP1 lower than FPP2.
Intermittent MIL
Conditions that are only present from time to
time are called intermittents. To resolve
intermittents, perform the following steps:
1. Evaluate the history of DTC’s observed
with this particular engine.
2. Evaluate the symptoms and conditions
described by the customer.
3. Use strategy-based diagnosis,
especially where it relates to the
elimination of bad connectors and
wiring.
4. When using a personal computer with
Ford software, data-capturing
capabilities are available that can assist
in detecting intermittents. Review the
user manual pdf document that is
included on the software CD.

DTC Retrieval Procedure
NOTE: DTC’s can be retrieved from the engine
control module (GCP) by using either the MIL or
an IBM compatible personal computer with a
USB port. Refer to Equipment Setup for
information about using a personal computer to
assist with unit diagnosis.
