OUT function is active (POSITIVE EB = 1 or 2).
Troubleshooting:
Check connector B1: it must be connected to the battery voltage (after the
main contactor).
218
SENS MOT
TEMP KO
Cause:
The output of the motor thermal sensor is out of range.
Troubleshooting:
- Check if the resistance of the sensor is what expected measuring its
resistance.
- Check the wiring.
- If the problem is not solved, replace the logic board.
219
PEB-PEVP
NOT OK
Cause:
The voltage of traction A17 pin is wrong, A17 pin voltage is +24V, from
DC-DC output, if the voltage is wrong,this alarm will appears
Troubleshooting:
- Check if the DC-DC works properly, if still has +24V output.
- Check the wiring,if A17 connected well?
- Check the fuse box if works properly,maybe the fuse is burned.
220
VKEY OFF
SHORTED
Cause
The logic board measures a key voltage that is constantly out of range, below
the minimum allowed value.
Troubleshooting
- Check that the battery has the same nominal voltage of the inverter.
- Check the battery voltage, if it is out of range replace the battery.
- In case the problem is not solved, replace the logic board.
221 HANDBRAKE
Cause:
Handbrake input is active.
Troubleshooting:
- Check that handbrake is not active by mistake.
- Check the SR/HB input state through the TESTER function.
- Check the wirings.
- Check if there are failures in the microswitches.
- If the problem is not solved, replace the logic board.
222
SEAT
MISMATCH
Cause
This alarm can appear only in a Tr Pump configuration. There is an
input mismatch between the traction controller and the pump controller
relatively to the seat input (A6): the two values recorded by the two
controllers are different.
Troubleshooting
- Check if there are wrong connections in the external wiring.
- Using the TESTER function verify that the seat inputs are in accordance
with the actual state of the external switch.
