3315624 - E3045 BOOT AND FUEL FLAP OPENING - Functional description

Functional description

The boot opening function can be activated:

• by the boot central locking switch H33 , located in the glove compartment;
• using the key in the rear lock (boot opening switch H71 );
• by the remote control receiver M35 .

When the vehicle is stationary, if the button H33 is pressed it energizes the boot opening relay J56 ; The enablement signal comes from pin 19 of connector A of multifunction control unit M40, which in turn receives information at pin 14 of connector A of instrument panel E50. Control unit internal software enables this function when the speedometer signal from the ABS control unit is lower than 2 km/h. The boot opening switch H71 energizes the relay J56 without any enablement. The remtoe control receiver M35 , when activated, energizes the coil for the relay J56 supplying an earth signal and thereby allowing the opening of the boot. The relay J56 is supplied directly from the battery, through the fuse line B62 , and controls the boot lock motor N57 . Fuel flap opening is controlled by the specific switch located among the controls on the tunnel H36 . When the engine is not running, the button of H36 - when pressed - energizes the fuel flap opening relay J57: the enablement signal arrives from terminal D+ of the alternator A10: it is the same signal which lights up the recharging warning light in the instrument panel ( See E5010 STARTING AND RECHARING ) and supplies the engine bay air temperature sensor of the additional heater See E6015 ADDITIONAL HEATER . The relay J57 is supplied directly from the battery, through the fuse line B61 , and it controls the fuel flap locking motor N58 .
