Description
Supplies
F08.04
ECU Input Supply
U104 / U106
D
1
Detected ECU voltage difference : Difference between U106 (SPU) and U104 (basket B2)
: 2V for 2s
--> 12VB – 12VBSLAVE > 2.00V
• Check U100, U104 and U106 supply voltage
• Check fuses
• Check supply voltage coherence between all ECU (more than 2000 V far during the first 4
seconds after start)
2
Overvoltage of U106 supply
--> 12VB > 17.00V
3
Overvoltage of U104 supply
--> 12VBSLAVE > 17.00V
F08.05
ECU Output Supply
U106 5V regul
D
1
Failure on regulated 5V output of U106 ECU (SPU 70-66) supplying position sensors
--> 5VSUPPLY = FAIL
• Check fuses
• Check the harness (check short circuit to power supply, to ground supply, open circuit…)
2
Failure on regulated 5V output of U104 ECU (basket slave node) supplying the joysticks
--> 5 V output is measured out the range [4.5;5.5] V and 5 V output not failing
• Check fuses
• Check the harness (check short circuit to power supply, to ground supply, open circuit…)
4
Failure on regulated 5V output of U104 ECU (basket slave node) supplying the joysticks
--> Detected failure on 5V output
Switch OFF/ON the machine, check the failure has gone (probable cause: internal failure of
the ECU)
F08.07
Circuit Selector
D
Incoherence on control box selector SA900 :
--> Check contactor output status

Connectors/Fuses
D
1
Supplies’ input detected as unplugged on connectors : Check the CN1.B connectors for
U106 ECU :
--> 12VD1<5.00V & 12VF1<5.00V
2
Supplies’ input detected as unplugged on connectors : Check the CN2.A connectors for
U106 ECU :
--> 12VD2<5.00V & 12VF2<5.00V
4
Supplies’ input detected as unplugged on connectors : Check the CN2.B connectors for
U106 ECU :
--> 12VD3<5.00V & 12VF3<5.00V
8
Supplies’ input detected as unplugged on connectors : Check the CN3.A connectors for
U106 ECU :
--> 12VD4<5.00V & 12VF4<5.00V
16
Supplies’ input detected as unplugged on connectors : Check the CN3.B connectors for
U106 ECU :
--> 12VD5<5.00V
