Fault Log Clearing OP4
OP4 is the option for clearing an inactive fault from the fault log of the GSC+. After a diagnostic fault is investigated and/or the fault is corrected, the fault should be cleared from the fault log. Fault log clearing helps prevent confusion during future service calls. After all diagnostic faults are cleared and the GSC+ is in normal mode, the "DIAG" indicator is not shown on the upper display. See Systems Operation, "Fault Log Viewing OP1" for more information.Procedure for Clearing Faults
Note: Service Mode cannot be entered when the engine control switch (ECS) is in the AUTO position.Note: An active shutdown indicator will be FLASHING. Active shutdown indicators must be deactivated in order to access the service mode. To temporarily change a shutdown fault from an active shutdown fault to an inactive shutdown fault, turn the ECS to the OFF/RESET position. Permanently changing a shutdown fault from an active shutdown fault requires correcting the active shutdown fault. The ECS must be turned to the OFF/RESET position. If the jumper from terminal 6 to terminal 9 is not installed on the ECS, the GSC+ does not power up in OFF/RESET. Any active shutdown fault must be corrected before the service mode is entered.
Turn the ECS to the STOP position in order to shut down the engine. Enter service mode and enter the password. "OP 4" is showing on the lower display. See Systems Operation, "Password Entry OP3" for more information on entering the password.
Press "SELECT" key. A CID FMI fault code is showing and the number of occurrences are showing. The lower display shows the hourmeter values of the first occurrence of the fault and the last occurrence of the fault.
Press "SELECT" key. The CID FMI fault code, hourmeter value, and fault count will flash.
Press and hold the "ENTER" key for two seconds. If there is only one CID FMI fault code, the CID FMI fault that was flashing disappears and the upper display is blank except for the flashing "SERV" indicator. "OP1" is showing on the lower display. Proceed to the next step. If there is more than one CID FMI fault code, the CID FMI that was flashing disappears. The upper display shows the next CID FMI fault code, the fault count, and the hourmeter value. Repeat steps 3 and 4 until all faults are erased. The lower display then shows OP 1. Proceed to step 5.
Press the "EXIT" key. "OP 1" is showing on the lower display.
Press the "EXIT" key. The display is now in normal mode.
