Upper Display that is showing a "CID 190 FMI 3" Diagnostic Fault CodeNote: The GSC+ response (alarm or shutdown) to four diagnostic faults is programmable by service personnel. The response that is usually programmed into the GSC+ is for an alarm. P04 would then be "0". When a shutdown response is programmed P04 would be "1". See Setpoint P04 within Systems Operation, "Engine/Generator Programming OP5". The diagnostic faults that can be programmed are oil pressure sensor CID 100, coolant temperature sensor CID 110, coolant loss sensor CID 111 and sensor power supply CID 269.The GSC+ has a fault log to help with troubleshooting of diagnostic faults. Inactive diagnostic fault codes (CID FMI) are recorded in the fault log for viewing at a later time. The total number of faults are shown on the upper display with the CID codes and the FMI codes. An active diagnostic alarm fault becomes inactive when the fault is no longer present and the ECS must be turned to OFF/RESET. The GSC+ stores a maximum of 12 diagnostic fault codes in the fault log. If an additional diagnostic fault becomes inactive, the GSC+ automatically clears the earliest diagnostic fault code. This fault code is put into the fault log by the GSC+. Inactive diagnostic fault codes that are more than 750 hours old are cleared automatically by the GSC+. Only diagnostic fault codes are recorded in the fault log. AL fault codes and SP fault codes are not recorded in the fault log. See Service Manual, "Fault Log Viewing OP1".Clear diagnostic fault codes from the fault log after correcting the fault. Clearing old codes will help avoid confusion. When all diagnostic faults are cleared from the fault log and no active diagnostic faults exist, the DIAG indicator is OFF. See System Operation, "Fault Log Clearing OP4".
