Fault Code (Lamp Flashes)
Fault Description
1- 1 High engine temp warning occurred (PTO was shutdown by ECM)
1- 2 High engine temp shutdown occurred (engine was shutdown by ECM)
1- 3 Low engine oil pressure occurred
1- 4 Engine alternator fault occurred
1- 5 Charging system voltage was incorrect (check charging system)
1- 6 Internal ECM fault
2- 1 Check ECM output fuse 1
2- 2 Check ECM output fuse 2
2- 3 Check ECM output fuse 3
2- 4 No power to all ECM output fuses (check main power relay)
2- 5 Leak in hydraulic system detected by optional leak detector (reels shutdown
and leak detector alarm sounds)
3- 1 Glow plug relay current was too high (check glow plug circuit)
3- 2 Start relay current was too high (check starting circuit)
3- 3 Fuel stop solenoid and fuel pump current were too high
3- 5 MSV2 current was too high (check front mow electrical circuit)
4- 1 SV1 current was too high (check cutting unit lift electrical circuit)
4- 2 SV3 current was too high (check cutting unit lift electrical circuit)
4- 3 SV2 current was too high (check cutting unit lift electrical circuit)
4- 4 SVRV current was too high (check cutting unit lift electrical circuit)
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. Operat or 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 a fault is not retrieved from ECM memory within 40
hours of machine operating time, the fault will be auto-
matically cleared. Cleared faults will be retained in ECM
memory and can be viewed by your Toro Distributor.
