Typical ExampleLocation of the ConnectorUse the following procedure to troubleshoot the service code information. Connect the 4C-8195 Control Service Tool to the service connector at the fuse panel.
Place the Caterpillar Monitoring System in service mode (mode 3). In order to place the Caterpillar Monitoring System in service mode, press and hold the mode switch of the control service tool. In the service mode, release the mode switch while the mode number "-3-" is shown on the display.Note: The service mode allows the technician to clear any service codes. The service mode will allow the technician to place any service codes on hold for further investigation. The diagnostic scrolling mode can be entered in order to see the active service codes.
The service code that is shown is on hold at this time. The display toggles between showing MID (5) and CID (8) and FMI (9). When no service codes are shown, screen (4) shows "---".
In order to view all the service codes, scroll through the service codes. In order to scroll through the service codes, press and hold the scroll switch of the control service tool. The display momentarily shows MID (5), CID (8) and FMI (9) for each service code. The word "End" is shown after the last service code in the list.
Place the desired service code on hold. In order to place the service code on hold, release the scroll switch when the desired service code is shown.
Use the information from the MID in order to determine the ECM that is generating the service code. If the MID is not 081, see Electrical System Schematic, "Module Identifier (MID) Table" of the machine that is being serviced. Use the table to determine the ECM that has detected the diagnostic code. Then see the service manual module for that electronic control. If the MID is 081, use this Service Manual Module to troubleshoot the diagnostic code that generated the service code.
