Information:
Use this procedure in order to troubleshoot the circuit for the secondary ECM ready lamp and the secondary ECM active lamp on the "Marine Power Display (MPD)" panel.Probable Causes
Battery voltage to the secondary ECM
Open circuit conditionRecommended Actions
Battery Voltage to the Secondary ECM
Connect Caterpillar Electronic Technician (ET). Establish communication with the secondary ECM. If communication with the secondary ECM cannot be established, verify that voltage is present at the secondary ECM. If voltage is not present at the keyswitch input on the secondary ECM, refer to Troubleshooting, "Engine Control Switch - Test". If battery voltage is not present at the inputs on the secondary ECM, refer to Troubleshooting, "Electrical Power Supply - Test".Open Circuit Condition
The secondary ECM ready lamp and the secondary ECM active lamp are activated by sinking drivers on the secondary ECM. The secondary ECM ready lamp and the secondary ECM active lamp are powered by the "MPD Breaker" in the MPD panel. An open circuit in either wire to the secondary ECM ready lamp or to the secondary ECM active lamp will cause the lamps to not illuminate. Refer to the electrical schematic in order to identify the wires to the secondary ECM ready lamp and to the secondary ECM active lamp. Check the wires for an open circuit. If the wires to the secondary ECM ready lamp or to the secondary ECM active lamp are OK, check for voltage to the one side of the lamps from the "MPD Breaker". If voltage is present, replace the lamp.
