•
No 1785 diagnostic codes are active.
• Diagnostic codes 0526-05 and 0526-06 are not
active.
•
No 0262 diagnostic codes are active.
Note: This diagnostic code will only appear if an
electronically controlled wastegate is installed.
System Response:
If equipped, the warning lamp will come on. The ECM
will log the diagnostic code and the ECM will trigger
a snapshot.
Possible Performance Effect:
•
The engine may not reach top RPM.
• The engine produces excessive black smoke.
•
The engine has low power.
Troubleshooting:
When this diagnostic code is registered, the code
indicates that a mechanical problem exists in the
intake air system. The electronic part of the control
system will be operating correctly.
Test the operation of the turbocharger wastegate.
Refer to Testing and Adjusting, “Turbocharger -
Inspect”.
Results:
•
OK – STOP.

CID 1779 FMI 05
Conditions Which Generate This Code:
This diagnostic code indicates that the Electronic
Control Module (ECM) has detected an open circuit
or low current condition in the solenoid for the fuel rail.
System Response:
If equipped, the warning light will come on and the
ECM will log the diagnostic code.
Possible Performance Effect:
An electrical fault may prevent the provision of
pressure to the fuel rail. This may result in the loss
of fuel injection. If the solenoid for the fuel rail pump
fails, it is likely that fuel will not be pumped into the
fuel rail. The engine will stop or the engine will not
start.
Perform the following diagnostic procedure: “Fuel
Rail Pump Solenoid - Test”
Results:
• OK – STOP.
i02527058
CID 1779 FMI 06
Conditions Which Generate This Code:
This diagnostic code indicates that the Electronic
Control Module (ECM) has detected a short circuit or
high current condition in the solenoid for the fuel rail.
System Response:
If equipped, the warning light will come on and the
ECM will log the diagnostic code.
Possible Performance Effect:
An electrical fault may prevent the provision of
pressure to the fuel rail. This may result in the loss
of fuel injection. If the solenoid for the fuel rail pump
fails, it is likely that fuel will not be pumped into the
fuel rail. The engine will stop or the engine will not
start.
Perform the following diagnostic procedure: “Fuel
Rail Pump Solenoid - Test”
Results:
