Diagnostics
One LED indicator will be flashing.(1) ""
One LED indicator will be on.(2) "DERATE"
Both LED indicators will be on.(3) "SHUTDOWN"
Both LED indicators will be flashing.(4) "LOSS OF COMMUNICATION"
(1) One LED will flash on the gauge that is related to the warning.
(2) One LED will be on continuously on the gauge that is related to the derate.
(3) Both LED indicators will be on continuously on the gauge that is related to the shutdown.
(4) Both LED indicators will flash if data link communication is lost.The tachometer is equipped with a Liquid Crystal Display (LCD) that can display SPN-FMI diagnostic information. If a diagnostic code is displayed on the LCD refer to the test steps that follow for the correct troubleshooting procedure.Test Step 1. Inspect the Electrical Connectors and the Wiring
Turn the keyswitch to the OFF position.
Thoroughly inspect the J1939 data link and all the connectors that are associated with the analog gauges. Refer to the following section of this manual , "Electrical Connectors - Inspect" for details.
Verify that all wires that are associated with the analog gauges are connected correctly. Expected Result:All connectors, pins, and sockets should be completely inserted and coupled. The harness and wiring should be free of corrosion, of abrasion, and of pinch points. Verify that all connections and grounds are tight and free of corrosion.Results:
OK - The wiring appears to be OK. Proceed to Test Step 2.
Not OK - There is a problem with the wiring.Repair: Repair the wiring for the circuit.Verify that the repair eliminates the problem.STOPTest Step 2. Check for Diagnostic Codes
Connect the Caterpillar Electronic Technician (ET) to the service tool connector.
Turn the keyswitch to the ON position.
Check for active diagnostic codes. Also check for logged diagnostic codes that may indicate an intermittent problem. Expected Result:No active diagnostic codes are present and no repeated logged diagnostic codes are present.Results:
OK - No diagnostic codes are present. Proceed to Test Step 3.
Not OK - There are diagnostic codes that are currently active.Repair: Troubleshoot any diagnostic codes before continuing with this procedure.If there are repeated logged diagnostic codes, refer to the following section of this manual , "Electrical Connectors - Inspect" in order to check for an intermittent problem.STOPTest Step 3. Check the LED Indicators
Turn the keyswitch to the ON position.
Check the LED indicators on each gauge. Expected Result:None of the LED indicators are illuminated.Results:
OK - None of the LED indicators are illuminated. Proceed to Test Step 4.
One LED flashing - Engine monitoring has indicated a warning.Repair: Refer to information that is found in the display's Systems Operation/Testing and Adjusting for more information.STOP
One LED ON - Engine monitoring has indicated a derate.Repair: Refer to information that is found in the display's Systems Operation/Testing and Adjusting for more information.STOP
Two LEDs ON - Engine monitoring has indicated a shutdown.Repair: Refer to information that is found in the display's Systems Operation/Testing and Adjusting for more information.STOP
Two LEDs Flashing - There has been a loss of data link communications.Repair: Refer to the information that is found in the appropriate Marine Engine Troubleshooting, "CAN Data Link Circuit - Test".STOPTest Step 4. Determine the Extent of the Problem
Turn the keyswitch to the ON position.
Start the engine and allow the engine run for several minutes.
Monitor the analog gauges for proper operation. Expected Result:All of the gauges are operating correctly.Results:
OK - The gauges are operating correctly.Repair: The problem is resolved. The original problem may have been caused by an intermittent problem. Refer to the following section of this manual , "Electrical Connectors - Inspect" in order to check for an intermittent problem.STOP
One or more gauges are not working - Proceed to Test Step 5.
All of the gauges are not working - Proceed to Test Step 6.Test Step 5. Check the Wiring to the Gauges
Inspect the wiring between the control module and the analog gauges. Expected Result:There are no problems with the wiring.Results:
OK - The wiring for the control module and for the suspect gauge appears to be OK.Repair: Connect the suspect gauge to another connector. If the suspect gauge does not work, replace the gauge.Verify that the repair eliminates the problem.STOP
Not OK - There is a problem with the wiring for the control module or for the suspect gauge.Repair: Repair the wiring or replace the section of harness.Verify that the repair eliminates the problem.STOPTest Step 6. Check the Power Supply
Disconnect the J44 engine connector from the control module.
Turn the keyswitch to the ON position.
Measure the voltage between P44-1 (switched +Battery) and P44-6 (-Battery). Expected Result:The correct voltage is between 22 VDC and 26 VDC for 24 volt systems. The correct voltage is between 9 VDC and 14 VDC on 12 volt systems.Results:
OK - The control module is receiving power.Repair: There may be a problem with the control module. Temporarily connect a new control module. If the repair resolves the original problem, permanently replace the control module. If the problem persists, there may be an intermittent problem in the circuit. Refer to the following section of this manual , "Electrical Connectors - Inspect" in order to check for an intermittent problem.STOP
Not OK - The control module is not receiving power.Repair: Check the wiring between the control module and the battery. If there is a problem with the wiring, repair the faulty wiring. Verify that the battery is charged.STOP
