which has to be replaced.
214
EVP
COIL
OPEN
Cause:
No load is connected between the NEVP output and the electrovalve positive
terminal.
Troubleshooting:
- Check the EVP condition.
- Check the EVP wiring.
- If the problem is not solved, replace the logic board.
215
EVP
DRIV.
SHORT.
Cause
- The EVP driver is shorted .
- The microcontroller detects a mismatch between the valve set-point and the
feedback of the EVP output.
Troubleshooting
- Check if there is a short circuit or a low-impedance conduction path between
the negative of the coil and -BATT.
216
EB. COIL
OPEN
Cause:
No load is connected between the NEB output and the EB positive terminal PEB
Troubleshooting:
Check the EB coil. Check the wiring. If the problem is not solved, replace the logic
board.
217
PEV NOT
OK
Cause:
The PEV connector (B1, only for ACE3 Premium version) is not connected to the
battery or the voltage is different from expected. This alarm occurs if one output
among EVP, EV1, EV2, EV3, EV4 and EV5 is present or the AUX 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-PEV
P 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.
