Circuit/System Verification

  1. Ignition On, observe the scan tool Flow Rates parameter. The ECM should be programmed with the flow rate numbers for the corresponding cylinders.
    • If flow rate numbers are not present, program the injector flow rate with a scan tool.
  2. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
