Fault Code
Fault Description Service Suggestions
28 48 VDC devices (motor/generator and all cut-
ting reel motors) are all off- line
Make sure that 48 VDC battery disconnect is
securely plugged in
Check 10A logic relay fuse
Check 48 VDC master fuse (250A maxi fuse)
Check 48 VDC battery system voltage
Check 48 VDC logic relay and circuit wiring
Check isolation module and circuit wiring
Check CAN- bus termination resistors and cir-
cuit wiring
29 48 VDC system (motor/generator and all cut-
ting reel motors) is under voltage
Check 48 VDC battery voltage
Check 48 VDC battery connections
Check internal motor/generator connections
Consider that motor/generator is faulty
30 48 VDC system (motor/generator and all cut-
ting reel motors) is over voltage
Check 48 VDC battery voltage
If engine is running when fault occurred, check
internal motor/generator connections
Consider that motor/generator is faulty
31 48 VDC system (motor/generator and all cut-
ting reel motors) logic voltage are all excessive
Check 48 VDC battery voltage
If engine is running when fault occurred, check
internal motor/generator connections
Consider that motor/generator is faulty
32 Cutting unit fault Contact Toro distributor for cutting unit service
assistance
33 Motor/generator fault Contact Toro distributor for motor/generator
service assistance
34 Master (TEC controller) fault Contact Toro distributor for TEC service assis-
tance
37 TEC output current to energize glow relay is
excessive
Check glow relay and circuit wiring

39 CAN- bus fault for #2 cutting reel motor Check CAN- bus connection to #2 motor
Verify battery power exists at #2 motor
Check CAN- bus termination resistors
40 CAN- bus fault for #3 cutting reel motor Check CAN- bus connection to #3 motor
Verify battery power exists at #3 motor
Check CAN- bus termination resistors
41 CAN- bus fault for #4 cutting reel motor Check CAN- bus connection to #4 motor
Verify battery power exists at #4 motor
Check CAN- bus termination resistors
42 CAN- bus fault for #5 cutting reel motor Check CAN- bus connection to #5 motor
Verify battery power exists at #5 motor
Check CAN- bus termination resistors
