System schematic for the spare output
The spare output on the GSC+ is strictly for the use of customers. The spare output is programmable in order to activate under a variety of conditions. The default parameter programming causes the GSC+ to activate the output when the engine is in cooldown mode. The GSC+ treats a CID 0334 FMI 04 as an alarm fault. For more information, see Systems Operation, "Spare Input/Output Programming OP6". The customer and/or the dealer are responsible for documenting and troubleshooting any connections to this output.The voltage on the spare output is approximately 5.0 DCV when there are no connections and when the spare output is not active. When the spare output is active, the voltage on the spare output is approximately 0 volts. The spare output is capable of drawing (sinking) approximately 100 mA.The possible cause of a CID 0334 FMI 04 is a short to negative battery of the spare output signal.Troubleshooting of a spare output fault is direct. The FMI defines the fault. FMI 04 occurs when the spare output is shorted to negative battery. In order to find the exact cause of the fault, use the following information.
FMI information
system schematic of spare output
documentation of the customer
documentation of the dealerTest Step 1. CHECK THE GENERATOR SET CONTROL
Verify that the CID 0334 FMI 04 diagnostic code is active.
Disconnect the wire from contact 36 of the GSC+.
Measure the voltage between contact 36 of the GSC+ and frame ground. Expected Result:The voltage is approximately 5 1.0 DCV.Results:
OK - The voltage is approximately 5 1.0 DCV. The voltage is correct. Proceed to test step 2.
NOT OK - The voltage is NOT approximately 5 1.0 DCV. The voltage is NOT correct. The GSC+ has failed.Repair: It is unlikely that the GSC+ has failed. Exit this diagnostic code procedure and repeat the CID 0334 FMI 04 diagnostic code procedure again. If the cause of the failure is still unknown, then replace the GSC+.STOPTest Step 2. CHECK FOR A SHORT TO "B-" IN THE WIRING OF THE SPARE OUTPUT
Disconnect the "B-" terminal from the battery.
Disconnect the wire from contact 36 of the GSC.
Disconnect the other end of the wire at the customer device.
Measure the resistance between the wire that was disconnected from contact 36 of the GSC+ and the "B-" contact of the GSC+. Expected Result:The resistance is greater than 5000 ohms.Results:
OK - The resistance is greater than 5000 ohms. The circuit is correct. 3
NOT OK - The resistance is less than 5000 ohms. The circuit is not correct. The spare output is shorted to negative battery (B-).Repair: Repair the wiring of the spare output.STOPTest Step 3. RECONNECT TO CUSTOMER DEVICE
Reconnect the wire to the customer device.
Reconnect the wire that was disconnected from contact 36 to the GSC+
Turn the ESC switch to STOP and check if the diagnostic code is still active. Expected Result:The diagnostic code is not active.Results:
OK - The diagnostic code is not active. It is likely that the problem was in the wiring harness or the problem is intermittent. Repair: Check the wiring between the GSC+ and the customer device for problems. Repair the wiring or replace the wiring if a problem is found. Watch for a reocurrence of the diagnostic code.STOP
NOT OK - The diagnostic code is still active. There may be a problem with the customer device.Repair: Tthe customer device may have failed. Refer to the customer documentation and the dealer documentation for the device.STOP
