SENR9982-01

CID 0002 FMI 05

Conditions Which Generate This Code:
This diagnostic code is designed to indicate an open
circuit (low current) in either the solenoid or the wiring
for the electronic unit injector for No. 2 cylinder.
The Electronic Control Module (ECM) detects the
following condition:
• A low current condition (open circuit) for each of
five consecutive attempts to operate
• Battery voltage is higher than 9 volts for 2 seconds.
System Response:
If equipped, the warning light will come on. The ECM
will log the diagnostic code.
Possible Performance Effect:
The engine will have low power and/or rough running.
Troubleshooting:
When an injector cutout test is performed, a faulty
electronic unit injector will indicate a low reading in
comparison with the other electronic unit injectors.
An electrical fault can prevent the electronic unit
injector from operating. An open circuit in the wiring
that is unique to the electronic unit injector will
prevent that individual electronic unit injector from
operating. On four cylinder engines, an open circuit
in common wiring within the ECM can prevent the
two electronic unit injectors that share that common
wiring from operating. On six cylinder engines, an
open circuit in common wiring within the ECM can
prevent the three electronic unit injectors that share
that common wiring from operating.
The ECM will continue to attempt to operate the
electronic unit injector after the diagnostic code has
been logged but an open circuit will prevent the
operation of the electronic unit injector.
Perform the following diagnostic procedure: "Injector
Solenoid Circuit - Test"
Results:
• OK – STOP.

CID 0002 FMI 06

Conditions Which Generate This Code:
This diagnostic code is designed to indicate a short
circuit (high current) in either the solenoid or the
wiring for the electronic unit injector for No. 2 cylinder.
The Electronic Control Module (ECM) detects the
following conditions:
• A high current condition (short circuit) for each of
five consecutive attempts to operate
• Battery voltage above 9 volts for 2 seconds
System Response:
If equipped, the warning light will come on. The ECM
will log the diagnostic code.
Possible Performance Effect:
The engine will have low power and/or rough running.
Troubleshooting:
When an injector cutout test is performed, a faulty
electronic unit injector will indicate a low reading in
comparison with the other electronic unit injectors.
An electrical fault can prevent the electronic unit
injector from operating. A short circuit in the wiring or
the ECM that is unique to one electronic unit injector
will prevent that individual electronic unit injector from
operating. On four cylinder engines, a short circuit
in common wiring within the ECM can prevent the
two electronic unit injectors that share that common
wiring from operating. On six cylinder engines, a
short circuit in common wiring within the ECM can
prevent the three electronic unit injectors that share
that common wiring from operating.
The ECM will continue to attempt to operate the
electronic unit injector after the diagnostic code
has been logged but a short circuit will prevent the
operation of the electronic unit injector.
Perform the following diagnostic procedure: "Injector
