DIAGNOSIS 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.
DIAGNOSIS 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.
