4 -- 5 MSV1 current was too high (check rear mow electrical circuit)
5 -- 1 Signal from optional leak detector was lost
5 -- 4 Internal ECM fault
Clearing Fault Codes
After fault codes have been retrieved, clearing of those
faults from ECM memory can be completed using the
following switch sequence:
1. Place machine switches in fault retrieval (see
above). The diagnostic light should be displaying the
fault codes.
2. Operator seat should remain UNOCCUPIED.
3. Move both mow/backlap levers to BACKLAP.
4. Move joystick to the RAISE position.
5. Monitor the diagnostic light for continuous flash-
ing indicating that all faults have been cleared from
ECM memory.
If more than 3 faults exist in the ECM memory, additional
faults can be retrieved using the above procedures. If a
fault is not retrieved from ECM memory within 40 hours
of machine operating time, the fault will be automatically
cleared.
