Problem 17
Engine shutdown occurs, high coolant temperature LED is lit. Test Procedure:Turn ECS to the reset position. If the high coolant temperature LED does not go out after engine is cool, do Problem 13. If the LED goes out check for possible causes for high coolant temperature. If no causes are found check the coolant temperature setting that has been programmed into the ECM (see Service Procedure A). It should be set for the specific engine model. See Identification section, character five for specific engine setpoints. Install an accurate coolant temperature gauge with the sensing bulb in area of high coolant flow, as close to temperature probe as possible. See note in Problem 16 under Test Procedures. Start the engine. Test Results:1. Coolant temperature setpoint is below proper shutdown setpoint. Temperature setpoint is not correct. See Service Procedure A.2. Temperature displayed by ECM and by gauge agree and is above the temperature setpoint. Setpoint is correct and high coolant temperature LED is still lit. Engine is overheating. Troubleshoot cooling system.3. Temperature displayed by ECM is 5°C (9°F) or higher than the temperature displayed by the gauge. Check temperature probe (see Service Procedure G). If it is good, repeat test. Be sure of gauge accuracy. If ECM continues to read high, replace the pressure/temperature transducer (sensor).4. Temperature displayed by ECM and by gauge agree and are below the temperature setpoint. Go to Problem 13.5. Temperature displayed on the ECM is the word "Hi" and the temperature on the gauge is below 98°C (208°F). Check for shorts in wiring to the pressure/temperature transducer (sensor). Also check the temperature probe (see Procedure G).Problem 18
Engine shutdown occurs, emergency stop LED's is lit. Test Procedure:Reset the emergency stop pushbutton by turning until it pops out. Turn the ECS to "OFF/RESET" position. Disconnect the wire from terminal 14 on the ECM if LED remains on after attempting to reset. Test Results:1. Emergency stop LED goes out when wire is disconnected. Emergency stop switch is stuck closed or grounded or wire is grounded. Repair as required.2. Emergency stop LED remains on. Move ECS to reset and back to manual position. If LED remains on, go to Problem 13.Problem 19
Engine shutdown occurs, optional reverse power relay LED is lit. Test Procedure:Turn the ECS to the reset position. If the reverse power LED does not go out, disconnect wire from terminal 13 on the ECM. Test Results:1. Reverse power LED goes out (resets) after resetting. Problem was reverse power fault. Control panel is OK.2. Reverse power LED goes out when wire is disconnected from terminal 13. Reverse power relay will not reset. Check wiring and replace reverse power relay as required.3. Reverse power LED remains lit. Go to Problem 13.Problem 20
No engine shutdown when a fault occurs. Test Procedure:Look at the ECM Display. If there is a diagnostic code displayed or a fault LED lit and the engine is not shut down, go to Step 1 (ETS and latching) (Problem 20) or Step 1A (ETR) (Problem 20)
