FLANGE-ADAPTER 7X2608 - Caterpillar

Probable Causes
Customer shutdown or external shutdown
Battery power to the Electronic Control Module (ECM)
Supply voltage for the speed/timing sensor
Fuel supply
Misfiring cylindersRecommended Actions
Customer Shutdown or External Shutdown
Check the ECM and the integrated temperature sensing module for logged codes of events that are shutdowns.Battery Power to the ECM
Refer to Troubleshooting, "Electrical Power Supply".
Inspect the ground strap and the battery for connections that are loose and/or corroded.
Inspect the ECM for proper installation of the connectors.
Check the 15 amp fuse in the interface box.Supply Voltage for the Speed/Timing Sensor
A loss of supply voltage to the speed/timing sensor will cause a shutdown. Refer to Troubleshooting, "Engine Speed/Timing Sensor".Fuel Supply
Make sure that fuel is supplied at a sufficient pressure that is stable. Make sure that the size of the fuel line is sufficient. Inspect the fuel system for leaks.The following conditions can cause the engine to malfunction:
Low fuel pressure
High fuel pressure
Poor fuel qualityMake sure that the fuel pressure is correct. When possible, interview the operator in order to determine if fuel quality is in question. Try to determine if the source of the fuel was changed.Inspect the fuel system components: fuel filter, gas pressure regulator, gas shutoff valve and fuel metering valve. Verify that the system's components are operating correctly.Replace the fuel filter, if necessary.Misfiring Cylinders
For a shutdown that is due to misfiring cylinders, the shutdown is likely to occur only when the engine is operating under a load.The Caterpillar Electronic Technician (ET) and the Exhaust Temperature Module can be used to detect a misfiring cylinder. Use the following procedure:
Operate the engine under load.
Monitor the exhaust temperatures of the cylinders with the exhaust temperature module. Identify the cylinder with the lower temperature.
Use Cat ET to observe the value of the transformer's secondary circuit. The misfiring cylinder will have a low value.Identify the misfiring cylinder. Check the following components for failure: spark plug, extender, ignition transformer and primary wiring. Inspect the extender for signs of pin holes and/or arcing.Refer to Troubleshooting, "Ignition Transformers Secondary Circuit and Spark Plugs".
