Code and Description Conditions which Generate this Code System Response
1-2 Cylinder #1 Injector : Erratic, Intermittent, or Incorrect The Electronic Control Module (ECM) the injector solenoid that cannot be accurately interpreted.
or
The ECM receives a signal from the injector solenoid that is invalid. The code is logged.
The ECM continues to energize the injector solenoid.

10-7 Cylinder #10 Injector : Not Responding Properly
11-7 Cylinder #11 Injector : Not Responding Properly
12-7 Cylinder #12 Injector : Not Responding Properly
13-7 Cylinder #13 Injector : Not Responding Properly
14-7 Cylinder #14 Injector : Not Responding Properly
15-7 Cylinder #15 Injector : Not Responding Properly
16-7 Cylinder #16 Injector : Not Responding Properly Background InformationA -2 code is activated when injector response to ECM current is not detected. Malfunctioning injectors can cause engine smoke and power issues.A -7 code is activated when injector response time to ECM current exceeds acceptable threshold. Injectors that are no longer responding correctly cause low power.Trim FilesWhen an injector is replaced, program the new injector code into the ECM. Refer to Troubleshooting, "Injector Trim File - Install" for information that is related to trim files. If the ECM is replaced, all the injector codes must be programmed into the new ECM. Refer to Troubleshooting, "ECM - Configure" for information that is related to the configuration of a new ECM.Note: Dual data link communications must be established between the service tool and the engine ECM prior to gaining access to some of the following tests. For information on dual data link communications, refer to Troubleshooting, "Electronic Service Tools" for details.Fuel System Verification Test - This test evaluates the health of each injector. The test determines if an injector needs to be replaced. When the test is performed, Cat ET indicates the status of
