Display shows that an F314 fault has occurred (PTO solenoid circuit has high current). (1) "Read Your Manual" symbol. (2) Readout. | |
The electronic control modules continually check for faults in the electrical circuits on the machine. When a fault is detected, the "Read Your Manual" symbol (1) will flash and the event will be stored in memory. Also, the corresponding fault code will flash on the four-digit readout (2) .
Note: During normal operation, the operator can choose whether or not to have the fault codes flash on the readout (2). Refer to Systems Operations, "Mode 1 - Operator Calibrations - Fault Codes ON/OFF" for more information.
Fault codes are a three-digit number preceded by the letter F. Each fault code identifies the machine circuit or sensor in which the fault occurs and the type of fault occuring. For example, fault code F314 means that there is high current in the PTO solenoid circuit. For a complete list of fault codes, see Testing and Adjusting, "Fault Code List".
The EMC has several service modes to assist with troubleshooting. The service modes that are directly involved with troubleshooting or diagnostics are:
- Mode 2 - View/Clear Stored Fault Codes
- Mode 3 - All Module Input Diagnostics
- Mode 4 - EMC Output Diagnostics
- Mode 5 - RHC Output Diagnostics
- Mode 6 - CCM Draft Control Output Diagnostics
- Mode 7 - CCM Transmission Control Output Diagnostics
Note: Modes 3, 4, 5, 6, and 7 are very useful for troubleshooting fault codes.
The View/Clear Stored Fault Mode (Mode 2) is the primary aid for troubleshooting fault codes. Mode 2 provides information such as the number of times a fault code has occurred and the hour at which the fault last occurred. Also, the fault codes can be cleared while in Mode 2. For a complete description of a particular service mode, see Systems Operation.
For the troubleshooting procedure of a particular fault code, see Testing and Adjusting, "Troubleshooting Procedures".
