Dune 125 - Dune X 125 - Euro 4
Electrical system
ELE SYS - 91
Short-circuit to positive: excessive voltage at PIN 11 or PIN 12 of the control unit connector.
Open circuit or short-circuit to negative: interruption of the circuit or null voltage between control unit
connector PIN 11 and 12.
Troubleshooting
Short-circuit to positive:
Disconnect the control unit connector and the sensor connector.
Verify that there is no short to battery positive on sensor connector PIN C (corresponding
to control unit connector PIN 11); if there is a short, restore the wiring harness.
Verify that there is no short to battery positive on sensor connector PIN D (corresponding
to control unit connector PIN 12); if there is a short, restore the wiring harness.
Open circuit:
Disconnect the control unit connector and the sensor connector.
Check the continuity of the wiring harness between the sensor connector and the control
unit connector: Control unit PIN 11 - sensor PIN C and control unit PIN 12 - sensor PIN D.
If necessary, restore the wiring harness.
If the wiring harness is intact and the error persists, proceed with the following checks.
Short circuit to negative:
Disconnect the sensor connector and the control unit connector.
Check the sensor connector PIN C ground insulation. If there is no insulation, restore the
wiring harness.
Check the sensor connector PIN D ground insulation. If there is no insulation, restore the
wiring harness.
If PIN C and PIN D are insulated from the ground and the error persists, this means that
there is a probable fault in the control unit.
Lambda probe heater P0135 -
shorted to positive / shorted to negative / open circuit.
Cause of error
Short-circuit to positive: excessive voltage at PIN 31 of the control unit connector.
Short circuit to negative: lack of insulation from ground on the sensor connector PIN A.
Open circuit: circuit interruption.
Troubleshooting
Short-circuit to positive:
Disconnect the control unit connector and the sensor connector.
Verify that there is no short to battery positive on sensor connector PIN B (corresponding to
control unit connector PIN 31); if there is a short, restore the wiring harness.
Open circuit:
Disconnect the control unit connector and the sensor connector.
