occurs again, this means it is current. Otherwise, it is a stored
error (carry out the specific checks anyway)
Throttle position sensor An interruption on the cable harness from PIN C3 of the ECU
to the sensor has been detected, or voltage equal to 5 V or
higher has been detected. The error status is always displayed
as MEM (stored). In order to identify whether an error is current
or stored, it is advisable to write down the error on paper so as
not to forget it, carry out the Error clearing operation and restart
the vehicle: if the error occurs again, this means it is current.
Otherwise, it is a stored error (carry out the specific checks
anyway)
Idle motor Abnormal voltage has been detected at PIN A1 and/or B1 and/
or C1 and/or D1 of the control unit. The error status is always
displayed as MEM (stored). In order to identify whether an error
is current or stored, it is advisable to write down the error on
paper so as not to forget it, carry out the Error clearing operation
and restart the vehicle: if the error occurs again, this means it
is current. Otherwise, it is a stored error (carry out the specific
checks anyway)
Low battery voltage Voltage below 7V has been detected at PINS G1. If MXV, as
there is no battery, check only generator, regulator and cable
harnesses
High battery voltage Voltage over 18V has been detected at PINS G1. If MXV, as
there is no battery, check only generator, regulator and cable
harnesses
Front injector Abnormal voltage has been detected at PIN A3 of the control
unit. The error status is always displayed as MEM (stored). In
order to identify whether an error is current or stored, it is ad-
visable to write down the error on paper so as not to forget it,
carry out the Error clearing operation and restart the vehicle: if
the error occurs again, this means it is current. Otherwise, it is
a stored error (carry out the specific checks anyway)
Rear injector Abnormal voltage has been detected at PIN A4 of the control
unit. The error status is always displayed as MEM (stored). In
order to identify whether an error is current or stored, it is ad-
visable to write down the error on paper so as not to forget it,
carry out the Error clearing operation and restart the vehicle: if
the error occurs again, this means it is current. Otherwise, it is
a stored error (carry out the specific checks anyway)
Front coil Irregular voltage has been detected at PIN M4 of the control
unit. The error status is always displayed as MEM (stored). In
order to identify whether an error is current or stored, it is ad-
visable to write down the error on paper so as not to forget it,
carry out the Error clearing operation and restart the vehicle: if
the error occurs again, this means it is current. Otherwise, it is
a stored error (carry out the specific checks anyway)
Rear coil Abnormal voltage has been detected at PIN L4 of the control
unit. The error status is always displayed as MEM (stored). In
order to identify whether an error is current or stored, it is ad-
visable to write down the error on paper so as not to forget it,
carry out the Error clearing operation and restart the vehicle: if
the error occurs again, this means it is current. Otherwise, it is
a stored error (carry out the specific checks anyway)
Short-circuited air temperature sensor Voltage equal to 0V has been detected at PIN B2 of the control
unit. The error status is always displayed as MEM (stored). In
order to identify whether an error is current or stored, it is ad-
visable to write down the error on paper so as not to forget it,
carry out the Error clearing operation and restart the vehicle: if
the error occurs again, this means it is current. Otherwise, it is
a stored error (carry out the specific checks anyway)
Open circuit air temperature sensor Voltage equal to 5V or higher has been detected at PIN B2 of
the control unit. The error status is always displayed as MEM
(stored). In order to identify whether an error is current or stor-
ed, it is advisable to write down the error on paper so as not to
forget it, carry out the Error clearing operation and restart the
vehicle: if the error occurs again, this means it is current. Oth-
erwise, it is a stored error (carry out the specific checks any-
way)
