RENR5042-02 25 Troubleshooting Section (Table 10, contd) Engine speed/timing sensors Inlet air temperature sensor Boost pressure sensor Coolant level sensor Fuel temperature sensor Fuel pressure sensor Auxiliary temperature sensor Auxiliary pressure sensor The monitoring system can be locked out. In order to change the settings, the monitoring system must be unlocked. Access the “Parameter Lockout” under the “Service” menu on Cat ET in order to unlock the monitoring system. Warnings, derates, and shutdowns can be disabled for any parameter or for all of the parameters. Note: Compare the FLS and the FTS from the ECM with the values that are listed on the engine information plate.
Only change the FLS and the FTS because of a mechanical change in the engine. The use of the wrong parameters could cause damage to the engine. The use of the wrong parameters may also void the Caterpillar warranty. Monitoring System The monitoring system determines the level of action that is taken by the ECM in response to a condition that can damage the engine. The monitoring of the various sensors by the ECM can be turned “On” or These conditions are identified by the ECM from the signals that are produced from the following sensors:
Engine oil pressure sensor Engine coolant temperature sensor Engine Parameters “Direct Fuel Control Mode” “Last Tool to change Customer Parameters” “Last Tool to change System Parameters” “Aux Press Temp Installation Status” “Aux Press Sensor Installation Status” “Total Tattletale” Information from Engine Information Plate “Engine Serial Number” “FLS” “FTS” Injector Codes Injector Code (1) Injector Code (2) Injector Code (3) Injector Code (4) Injector Code (5) Injector Code (6)
