LOCKWASHER 5F8916 - Caterpillar

The CCM has internal troubleshooting to aid in solving various system problems.Note: For the 117-6170 System Communication Modules, the logged faults will appear on the display of the CCM in 60 second intervals. The error codes will be displayed for 2 seconds. The flashing fault log will not appear for any other version of CCM. The fault log can be cleared by using the PC software for the CCM.
Table 1
CCM Error Codes    
CCM Error Code     Explanation     Action Required    
E00     No fault, normal operating mode     None    
E01     Setpoint (EEPROM) fault     CCM passwords, unit addresses, or communication setups are corrupted. Reprogram from Phone-Book and Utilities pull-down menus.    
E02     M5X message error     Check customer generated M5X code    
E03     Memory backup battery is weak     Change battery. Refer to Operation and Maintenance Manual, "Battery - Replace"    
E04     RS-232C link short circuit fault     Check RS-232C cable, PC port, and CCM port    
E05     Internal buffer overflow on RS-232C or Data Link fault     Possibly caused by a slower than acceptable communication rate from the RS-232C port or an open CAT Data Link connection during RS-232C transmission. Increase communication rate and check CAT Data Link wires.    
E06     Invalid CAT Data Link Message fault     Caused by:
1. Too much traffic on CAT Data Link.
2. CAT Data Link wires too long.
Remove ECAP or other Caterpillar electronic service tool devices overloading CAT Data Link and check CAT Data Link wires.    
E07     Miscellaneous CAT Data Link Fault     Caused by:
1. (+/-) CAT Data Link shorted to (+/-) battery.
2. Internal hardware fault in CCM.
Check CAT Data Link wiring and then replace CCM if wiring is good.    
E08     RS-232C link message fault (parity, data size)     Check RS-232C protocol (communication rate, data bits, stop bits, parity) of CCM and PC.    
888     Internal CCM fault     Replace the CCM.
