PUMP GP-OIL 6N2450 - Caterpillar

Note: The following procedure is applicable only when the GSC determines the value of the hourmeter on the GSC display. The setpoint P23 is programmed to 0 or 1. When the engine setpoint P23 is programmed to 2 ( EUI Engine), the value for the hourmeter on the GSC display is determined by the engine ECM instead of by the GSC. OP7 is not available for programming. OP7 is the option for programming the hours that are shown on the hourmeter. The hours can be increased but not decreased. This allows the hours on a new GSC to exactly match the hours of a GSC that is being replaced. This improves the tracking of engine maintenance such as oil changes when the GSC is replaced. Also, if the GSC is moved from one engine to another engine, the hours can be changed in order to match the new engine. This procedure can take place when the reprogrammed hours are more than the original hours. If the hourmeter shows all dashes, the hours can not be reprogrammed. If the hourmeter shows all dashes instead of a reasonable numeric value then see Testing and Adjusting, "Troubleshooting Diagnostic Codes". Procedure For Programming The Hourmeter
This procedure uses a new GSC with 0 hours as an example. The hourmeter in the new GSC will be set to a value of 1,234 hours. The value must be higher than the original value. Note: Service mode cannot be entered when the ECS is in the AUTO position. Note: Any active shutdown fault must be made inactive in order to access service mode. A FLASHING shutdown indicator means that a shutdown fault exists. To temporarily change a shutdown fault from an active shutdown fault to an inactive shutdown fault, turn the ECS to the OFF/RESET position. To permanently change a shutdown fault from an active shutdown fault to an inactive shutdown fault, the fault must not be occurring. Also, 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, then the GSC will not power up in OFF/RESET and any active shutdown fault must be corrected before entering service mode.
Turn the ECS to the STOP position in order to shut down the engine. Enter service mode and enter the password. "OP 1" is showing on lower display. See Systems Operation, "Service Mode" for more information. See Systems Operation, "Password Entry OP3" for more information.
