Check the + 12 V after relay supply of the turbocharging solenoid valve on the following connection:
•3FB of component 1475.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
If the fault is stored, clear the fault and run command AC004.
If, when command AC004, DF054 Turbocharging solenoid valve control circuit 1.DEF is present or stored,
contact the Techline.
