DIAGNOSTICS INSTRUMENT: STATUSES
Variable geometry intake
•
not active/active
NOTE: It indicates whether the control unit has sent the command to the variable geometry control unit
to lift the ducts.
DIAGNOSTICS INSTRUMENT: ACTIVATION
Variable geometry intake control
NOTE: The injection ECU sends the command to the variable geometry control unit to lift the ducts. In
the version PGDS 3.0.0 for Navigator, the command works once only, then it is used to take the key to
OFF and wait if communication with the control unit is lost.
DIAGNOSIS INSTRUMENT: ERRORS
Variable geometry intake P0447
•
shorted to positive / shorted to negative / open circuit / signal not valid.
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 62. If shorted to negative:
no voltage has been detected. If the circuit is open: an interruption has been detected. If
signal is not valid: PIN 76 detects a battery voltage set by the variable geometry control unit
to indicate error detection. The instrument panel does not indicate the presence of this error
even in the ATT status.
Troubleshooting
•
If shorted to positive: if a voltage higher than 5V is detected, disconnect the variable geom-
etry control unit connector and check with key ON the voltage to PIN 2: if it is higher than 5
V, restore cable harness; if equal to zero, replace the variable geometry control unit.
•
If shorted to negative: disconnect the variable geometry control unit connector and the in-
jection ECU connector and check continuity to ground of the light blue cable: if there is
continuity with the ground, restore cable harness; if insulated from ground, replace the var-
iable geometry control unit.
•
If the circuit is open: check the connector of the variable geometry control unit and the in-
jection control unit: if they are not OK, restore; if they are OK, check continuity on the light
blue cable: if not OK, restore; if OK, replace the variable geometry control unit.
•
If signal is not valid: check the connector of the variable geometry control unit, the motor
cable connector and the motor connector (check the PINS of the connector, installed directly
on the motor): if not OK, restore; if OK, check electrical characteristics of the motor: if not
OK, replace; if OK, check, with connector of the variable geometry control unit and connector
of the motor disconnected and intermediate connector connected, if the red and black cables
are in continuity, insulated from ground and without voltage and insulated one from the other:
if not OK, restore; if OK, check if the electrical motor pin is correctly inserted in the cavity of
