Fuel Injector Flow Rate Programming
Circuit/System Description
The control functions for the fuel injection system are
integrated in the engine control module (ECM). Each injectors flow
rate information, or injection quantity adjustment flow rate
numbers, and cylinder position are stored in the memory of the ECM.
The fuel injector flow rate programming must be done when any of
the following procedures are performed:
• |
A fuel injector is
replaced |
Injector Flow Rate Programming
2. |
Record all the injection
quantity adjustment codes from the corresponding cylinder from each
injector that is being replaced or from all injectors if the ECM
was replaced. |
|
Note: Enter the 7
digit injection quantity adjustment code from the injector or
injectors that is printed on the top.
|
3. |
Perform the scan tool Injector
Flow Rate Programming and follow the instructions on the
screen. |
Repair Verification
1. |
Install any components or
connectors that have been removed or replaced during
diagnosis. |
2. |
Perform any adjustment,
programming or setup procedures that are required when a component
or module is removed or replaced. |
3. |
Ignition OFF for 60
seconds. |
4. |
Ignition ON, engine
OFF. |
6. |
If the repair was related to a
DTC, duplicate the Conditions for Running the DTC and use the
Freeze Frame/Failure Records, if applicable, in order to verify the
DTC does not reset. If the DTC resets or another DTC is present,
refer to the
Diagnostic Trouble Code (DTC) List - Vehicle and perform the
appropriate diagnostic procedure. |
