Hardware
protection in T1
detects a short
circuit or current
through the main
contactor (Q10)
exceeds valid limit
values. Maximum
value = 2.5A,
continuous value =
1.5A
Everything is
stopped at once,
the parking brake
is activated, and
the main
contactor opens
High power
consumption or
short circuit
1: Check for overcurrent or short
circuit:
• Check the ohms and the
amperes of the component,
compare them to the setpoint
values if they outside the
accepted range.
• Check the connections and
wiring harness for short-circuit.
• Check that the component does
not seize or is jammed.
• If points 1-3 are OK, it indicates
that the output stage is short
circuited - Replace the power-
supplying component

The motor control
detects missing
phases to the
motor
Everything is
stopped at once,
the parking brake
is activated, and
the main
contactor opens
1: Short circuit in
motor
2: Low power
consumption
or break
3: Short circuit in
power stage
1: Check the motor
• Disconnect motor wiring
including sensor wires.
• Insulation test. Check that the
coils are not electrically
connected to the chassis.
Replace M1 if the motor is not
isolated
2: Check wiring and component
after the break
• Disconnect the battery
• Visually check the wiring
harness
• Using instruments, check that
there is no break in any wire
• Check the Ohms and the
Amperes of the component,
compare them to the setpoint
values, and replace the unit if
they are outside the accepted
range.
• Reconnect the battery. Measure
and check the voltage for the
activated functions.
3: Replace T1
