WASHER 5K2669 - Caterpillar

The CCM has internal troubleshooting to aid in solving various system problems.
Table 1
CCM Error Codes
CCM Error Code Explanation Action Required
E00 (all bits zero) No fault, normal operating mode None
E01 (bit 1 set) Setpoint fault CCM passwords or communication setups are corrupted. Reprogram from Connection and Setup pull-down menus.
E02 (bit 2 set) M50 message error Check customer generated M50 code
E03 (bit 3 set) Memory backup battery is weak Change battery. Refer to Operation and Maintenance Manual, SEBU7014, "Battery - Replace" in this manual.
E04 (bit 4 set) RS-232C link short circuit fault Check RS-232C cable, PC port, and CCM port
E05 (bit 5 set) 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 (bit 6 set) Invalid CAT Data Link Message fault Caused by:
1. Too much traffic on CAT Data Link.
2. CAT Data Link wires too long.
E07 (bit 7 set) 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 (bit 8 set) RS-232C link message fault (parity, data size) Check RS-232C protocol (communication rate, data bits, stop bits, parity) of CCM and host equipment.
E.. (bits 16-9) - Set to zero (0). Reserved for future use.
