CAN
communication
problem, A5 cannot
send to T1
Everything is
stopped at once,
the parking brake
is activated, and
the main
contactor opens
1: Error on CAN
bus wiring or
connection
2: CAN module
in A5 defective
1: Check the CAN bus
• Check that CAN bus is intact in
terms of wiring harness,
resistance and connectors.
Disconnect the battery. Check
that the resistance between
(X41:3) and (X41:4) is 54 - 66
ohms.
• Check that the CAN wiring
harness is not pinched.
Measure resistance between
the chassis and CAN connector.
Limit value >24 kOhm

connected to the chassis.
Replace M1 if the motor is not
isolated
2: Check the motor wiring
harness
• Visual check of the motor wiring
harness. Check that there is no
contact between the pole
connections on the motor/motor
control. Search for contact and
damaged insulation on the
wiring harness.
• Disconnect the motor wiring
harness at the motor control and
the motor and measure the
ohms of the wiring harness
between the phases and verify
that there is no contact.
