Information:


Table 1
1. If the check engine lamp turned on there will be a logged diagnostic trouble code. Refer to the appropriate troubleshooting procedure in order to determine if the driver's indicated symptoms agree with the symptoms that are associated with the code. If the driver's symptoms do not match the symptoms of the code, troubleshooting the code will not correct the problem. Review the snapshots that are associated with each code in order to determine the operating conditions of the engine during the occurrence of the problem. Try to duplicate these conditions. If there are not any logged codes check the battery connections for the Engine Control Module (ECM). Refer to Troubleshooting, "Electrical Power Supply - Test".
2. If the problem is easily repeatable, take the vehicle for a test drive while Caterpillar Electronic Technician (ET) is connected to the data link connector. Note the conditions when the problem occurs. The operator should be prepared to take snapshot data by using Cat ET or the cruise control set/resume switches. Ensure that you operate the vehicle after correcting the problem. During vehicle operation, duplicate the operating conditions before releasing the vehicle in order to verify that the problem has been corrected.
3. If the vehicle has been to other shops for the same problem, call the other shops in order to determine the type of work that has been done. Avoid replacing the same components again, unless you are absolutely sure that the components are the problem. If a component has recently been changed, it is unlikely that the component will fail again.
4. Troubleshoot the reason that the engine will not start. Repair the reason that the engine does not start. When you repair the reason that the engine did not start you should repair the reason that the engine shut down. If the engine shut down completely, check the ECM battery connections, the ground connections, the fuel system, the fuel, the primary engine speed/timing sensor and the secondary engine speed/timing sensor. If the engine will not restart, refer to Troubleshooting, "Engine Cranks but Does Not Start".
5. If the problem is easily repeatable, refer to Troubleshooting, "Engine Misfires, Runs Rough or Is Unstable".
If the problem is not easily repeatable, refer to Troubleshooting, "Power is Intermittently Low or Power Cutout Is Intermittent".
6. If other devices on the vehicle are affected, something is wrong with the vehicle wiring. Refer to Troubleshooting, "Electrical Power Supply - Test" for information on inspecting the ECM battery connections.
7. Operate the engine under similar load conditions. Check the low pressure fuel lines for restrictions. Also check the fuel/water separator and the fuel tanks for foreign objects that are blocking the fuel supply.
8. Operate the engine at this temperature. Attempt to duplicate the problem.
9. When possible, troubleshoot the problem in this temperature range.
10. If the problem seems to occur during the rain or a washing, thoroughly inspect the connectors for moisture. Refer to Troubleshooting, "Electrical Connectors - Inspect".
11. If the problem occurs at a specific vehicle speed, check the
