Can Bus Fault
There is no dialog between one or
more electronic control units.
- Check for each of the electronic control units if their LED is
permanently on:
• If all of the LEDs are lit: perform tests §1-1 and §1-2.
• If at least one LED is switched off: perform test §2.
1-1 Tests to be performed 5 BUS-CAN connectors connected.
- Access platform switched on: measure the voltage between the
BUS-CAN wires and the negative (wire 103).
BUS-CAN wire Theoretical voltage
(V)
The signal must be
between
112
~2.4V
2.3V < < 2.7V
113
~2.6V
2.3V < < 2.7V
- Access platform switched off: measure the resistance of the BUS-CAN
circuit between wires 112 and 113 at the diagnostics plug:
• The resistance is 95 Ω.
Disconnect successively

- Access platform switched off: for each of the electronic control
units, measure the resistance between the 112 and 113 inputs
at the CAN connector:
• The resistance is 470 Ω.
1-2 Tests to be performed 5 BUS-CAN connectors disconnected.
- Disconnect the BUS-CAN harnesses (wires 113 and 112) at each
end (variable speed controller, base electronic control unit, basket
electronic control unit).
- For wires 113 and 112, check the continuity between each of them and
each end: check that there is no continuity between wires 113 and 112.
- Check the connections, the shielding (variable speed controller
section - BASE box).
- Put the contact bomb on the BUS-CAN connections, bypass the
BUS-CAN lines with external wires to determine if the wires or
connections are defective.
2-Test to be performed if at least one LED is switched off
- Check when switched off if the LED flashes for 0.5 seconds:
• Check the power supply between terminals B+, B+2 (positive
terminals) and B/NEG, C/NEG, D/NEG (negative terminals) of the
control unit which is causing the problem.
• Check the connections of all power supplies mentioned above
- Check the quality of the battery negative signal: wire no. 103.
• Ensure that all of the connections of wire 103 are correctly
attached and connected (crimping of wires not damaged, quality
of contacts, etc.) in the electrical sockets, the terminal blocks, the
terminals, etc.
- Check the quality of the battery positive signal: wire no. 106.
• Ensure that all of the connections of wire 106 are correctly
attached and connected (crimping of wires not damaged, quality
of contacts, etc.) in the electrical sockets, the terminal blocks, the
terminals, etc.
