Electrical system
panel: if voltage is below 1 V, it means that on the blue cable there is a short circuit to ground;
if voltage is above 1 V (approximately battery voltage), replace the "-" button sensor.
Indication on diagnostic tool "Invalid data due to open circuit error";
•
CASE 1): if this status is displayed only with control not activated, it means that circuit from
PIN 15 to PIN 34 of the instrument panel is interrupted or that PIN 34 is not grounded: check
the instrument panel connector and the "-" button connector: if they are not OK, restore; if
they are OK, check continuity on the blue cable: if it is not OK, restore; if it is OK, check
continuity on the black cable from the "-" button connector to PIN 34 of the instrument panel:
if it is not OK, restore; if it is OK, check continuity of the "-" button from the "-" button connector
(between brown cable and blue cable): if it is not OK, change the control; if it is OK, check,
with key to ON, that the black cable is not grounded and then replace the instrument panel.
•
CASE 2): if this status is displayed only with control activated, it means that circuit from PIN
22 to PIN 34 of the instrument panel is interrupted: check the instrument panel connector
and the "-" button connector: if they are not OK, restore; if they are OK, check continuity on
the red cable: if it is not OK, restore; if it is OK, check, with control activated, that there is
not continuity of the "-" button from the "-" button connector (between brown cable and red
cable) and then replace the control.
NOTES: The control unit can not detect faults due to failed cable continuity
P0570 "+" command plausibility
Electrical diagnosis:
•
Open contacts/Closed contacts.
Error cause:
•
With open contacts, a voltage over zero is detected at the same time at PIN 19 and PIN 20
of the instrument panel.
•
With closed contacts, zero voltage is detected at the same time at PIN 19 and PIN 20 of the
instrument panel.
Troubleshooting:
The instrument panel expects to find, at either of the two PINs, a voltage over approx. 1 V and at the
same time a voltage below 1 V at the other PIN; if this does not occur, the instrument panel outputs the
information to the control unit that shows this error.
Indication on diagnostic tool "Invalid data due to short circuit error";
•
CASE 1): if this status is displayed with control not activated only, it means that a voltage
below 1V, instead of battery, is detected at PIN 19 of the instrument panel; disconnect the
"+" button connector and read voltage at PIN 19 of the instrument panel: if voltage is below
1 V, it means that on the white cable there is a short circuit to ground; if voltage is above 1
V (approximately battery voltage), replace the "+" button sensor.
