DIAGNOSTIC TOOL: STATUSES
"+" button:
Pressed/Released/Invalid data due to open circuit error/Invalid data due to short circuit error.
"-" button:
Pressed/Released/Invalid data due to open circuit error/Invalid data due to short circuit error
DIAGNOSTIC TOOL: ELECTRICAL ERRORS
P0569 "-" 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 22 and PIN 15
of the instrument panel.
•
With closed contacts, zero voltage is detected at the same time at PIN 22 and PIN 15 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 22 of the instrument panel; disconnect the
"-" button connector and read voltage at PIN 22 of the instrument panel: if voltage is below
1 V, it means that on the red cable there is a short circuit to ground; if voltage is above 1 V
(approximately battery voltage), replace the "-" button sensor.
•
CASE 2): if this status is displayed only with control activated, it means that at that moment
a voltage below 1V, instead of battery, is being detected at PIN 15 of the instrument panel;
disconnect the gearshift control connector and read voltage at PIN 15 of the instrument
