Diagnostic Codes.
Turn the ECS to the OFF/RESET position.
Connect the Caterpillar Electronic Technician (ET).
Turn the ECS to the STOP position.
Observe the diagnostic codes on the Cat ET.Note: The secondary ECM will assume control of an 8 cylinder engine or of a 12 cylinder engine if two or more diagnostic codes for the injectors are present. The secondary ECM will assume control of a 16 cylinder engine if four or more diagnostic codes for the injectors are present.Expected Result:Logged diagnostic codes are present.Results:
OK - A diagnostic code of CID 0579 - FMI 05 or a diagnostic code of CID 0579 - FMI 06 is present. Proceed to Test Step 8.
OK - An error code for the fuel injectors is present. Repair: Perform the diagnostic functional test Troubleshooting, "Injector Solenoids".STOP
Not OK - No logged diagnostic codes are present. Proceed to Test Step 4.Test Step 4. Check the Primary ECM Heartbeat Signal at the Primary ECM.
Turn the ECS to the OFF/RESET position.
Disconnect the primary ECM connector J2/P2.
Remove wire C401 from the primary ECM connector P2-28. Install a wire jumper with sockets on both ends into ECM connector P2-28.
Connect a multimeter that is capable of reading frequency between the wire jumper in P2-28 and the engine ground.
Reconnect the primary ECM connector J2/P2.
Turn the ECS to the STOP position.
Observe the frequency of the primary ECM heartbeat signal on the multimeter display. If a number does not appear on the multimeter display, verify the connections. Measure the frequency from another digital sensor. Verify that the multimeter is operating correctly.
Turn the ECS to the OFF/RESET position.
Remove the wire jumper. Reconnect all wires and connectors.Expected Result:The frequency is between 15.67 and 16.33 Hz.Results:
OK - The frequency is between 15.67 and 16.33 Hz. Proceed to Test Step 5.
Not OK - The frequency is not between 15.67 and 16.33 Hz. The primary ECM heartbeat signal is not within the frequency range.Repair: Verify that the proper software has been installed. Verify that the primary ECM is receiving the correct voltage. Perform the diagnostic functional test Troubleshooting, "Electrical Power Supply".STOPTest Step 5. Check the Primary ECM Heartbeat Signal at the Secondary ECM.
Turn the ECS to the OFF/RESET position.
Disconnect the secondary ECM connector J1/P1.
Remove the wire C401 from the secondary ECM connector P1-21.
Connect a multimeter that is capable of reading frequency between wire C401 and engine ground.
Reconnect the secondary ECM connector J1/P1.
Turn the ECS to the STOP position.
Observe the frequency of the primary ECM heartbeat signal on the multimeter display. If a number does not appear on the multimeter display, verify the connections. Measure the frequency from another digital sensor. Verify that the multimeter is operating correctly.
