Electrical system
Pin-out:
1. Voltage 5V
2. Ground connection
THE CONNECTION DIAGRAMS ARE IN THE ELECTRICAL SYSTEM SECTIONS; PAY ATTENTION
TO THESE DIAGRAMS AS THEY SHOW THE CONNECTOR/COMPONENT AS VIEWED FROM
THE CABLE HARNESS SIDE, THAT IS LOOKING AT THE CABLES WHEN GOING OUT OF THE
"MAIN" CABLE HARNESS AND INTO THE CONNECTOR/COMPONENT.
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING, CAREFULLY READ THE GENERAL TROU-
BLESHOOTING CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGINNING OF THE CHECK
AND CONTROL SECTION IN THE ELECTRICAL SYSTEM CHAPTER.
Instrument panel
ERROR DSB 06
Error cause
•
An oil sensor failure is signalled when it is detected that the sensor circuit is open or shorted
to positive.
Troubleshooting
•
Check the sensor connector and the instrument panel connector (PINS 10 and 30): If not
OK, restore; if OK, check the continuity of the pink cable between the sensor connector and
the instrument panel connector PIN 10: if not OK, restore the cable harness; if OK, check
the correct sensor resistance: if it is not OK, replace the sensor; if it is OK, check the con-
tinuity of the brown/black cable between the sensor connector and PIN 30 of the instrument
panel connector: If not OK, restore the cable harness; if OK, with key set to ON, check if
there is voltage at the sensor connector PIN 1: if there is no voltage, replace the instrument
panel; if there is approximately 12V, restore the cable harness (there is a short circuit in the
battery). If there is 5V voltage, connect a 10 kOhm resistance to PIN 1 of the sensor con-
nector and to the vehicle ground connection: if, with key set to KEY ON, the voltage
measured upstream the resistance decreases, replace the instrument panel. If voltage con-
tinues to be approximately 5V, restore the pink cable (there is a short circuit at + 5V).
Notes
If a short circuit to ground is detected at PIN 10 of the instrument panel connector, the display will show
a temperature full scale indication.
Check the earth insulation of the sensor connector pink cable: if there is a connection, restore the cable
harness; if it is earth insulated, check that sensor resistance is correct: if it is not OK, replace the sensor;
if it is OK, replace the instrument panel.
