214 EVP COIL OPEN
No load is connected between
the EVP output (A24) and the
electrovalve positive terminal.
"1- Check the EVP
condition.
2- Check the EVP wiring.
3- If the problem is not
solved, replace the logic
board."
215 EVP DRIV. SHORT.
"1- The EVP driver (output A24) is
shorted.
2- The microcontroller detects a
mismatch between the valve set-
point and the feedback of the EVP
output."
"1- Check if there is a short
circuit or a low-impedance
conduction path
between the negative of the
coil and -B.
2- Collect information about:
o the voltage applied across
the EVP coil,
o the current in the coil,
o features of the coil.
Ask for assistance to EP
in order to verify that the
software diagnoses are
in accordance with the type
of coil employed.
If the problem is not solved,
it could be necessary to
replace the controller."
216 EB. COIL OPEN
This fault appears when no load is
connected between the NEB output
(A4) and the EB positive terminal
PEB (A2).
"1- Check the EB coil.
2- Check the wiring.
3- If the problem is not
solved, replace the logic
board."
217 PEV NOT OK
Terminal PCOM is not connected to
the battery or the voltage is different
from that defined by parameter
SET POSITIVE PEB (see the
ADJUSTMENTS list, paragraph
8.2.3). This alarm can occur if
output NAUX1 is present (and the
related setting is active) or the AUX
OUT function is active.
"1- Check PCOM terminal:
it must be connected to the
battery voltage (after
the main contactor).
2- Set the nominal PCOM
voltage in parameter SET
POSITIVE PEB in
ADJUSTMENTS list (see
paragraph 8.2.3)."
