Electrical system
6. B track signal (light blue cable)
DIAGNOSTIC TOOL: ELECTRICAL ERRORS
P0225 Track A handle position sensor
Electrical diagnosis:
•
short circuit to positive / open circuit, short circuit to negative
Error cause
•
Short-circuit to positive: an excessive voltage was detected at PIN 39 of the ENGINE con-
nector.
•
If open circuit, short circuit to negative: a voltage equal to zero was detected at PIN 39 of
the ENGINE connector.
This error is indicated by flashing the general warning light and by lighting up in a fixed manner the MI
warning light.
Troubleshooting
•
Short-circuit to positive: check the value indicated by the parameter handle position sensor
track A: disconnect the connector and read the value indicated by the diagnostic tool: if the
voltage does not vary, there is a short circuit on the wiring harness of the relative cable, if
the voltage goes to zero, replace the handle sensor.
•
open circuit, short circuit to negative: check the handle sensor connector and engine control
unit connector, if not ok restore, if ok check cable continuity between the two terminals, if
not ok restore, if ok check the ground insulation of the cable (from the handle sensor con-
nector or control unit connector): if not ground insulated, restore the wiring harness, if ground
insulated check, with key ON, that power supply is present at PIN 1 of the potentiometer
and that the ground is present at PIN 2, if present correctly replace the handle sensor, if not
present check the continuity of the malfunctioning cable: if the continuity is present replace
the control unit, if not present replace the wiring harness
P2130 Track B handle position sensor
Electrical diagnosis:
•
short circuit to positive / open circuit, short circuit to negative
Error cause
•
Short-circuit to positive: an excessive voltage was detected at PIN 13 of the ENGINE con-
nector.
•
If open circuit, short circuit to negative: voltage equal to zero was detected at PIN 13 of the
ENGINE connector
This error is indicated by flashing the general warning light and by lighting up in a fixed manner the MI
warning light
