Description of operation

DESCRIPTION OF OPERATION

The foglamp relay in junction unitB1 (connector D), controls the foglamps circuit.

The foglamp relay coil is supplied, with the side lights on, by fuse line F5 of B1 (see E2010 - TURN LIGHTS/NUMBER PLATE); it is energised by the "on" signal from the button in the switch control group H90 (by pin 12 of connector A). The same line also illuminates the button itself.

The foglamp relay power line is supplied directly from the battery through the line of fuse F19 of junction unit B1 and fuseB50 that protects a series of optional services: when the relay is energised, it supplies the two foglamps F15 (left) and F16 (right).

The headlamps supply line also sends a signal to the switch controlB>H90 (pin 1 of connector A) to enable rear foglamps on (see E2031 - REAR FOGLAMPS). All the switch control group H90 is however lit from injection switch power supply(INT) by the line (pin 5 of connector A ) protected by fuse F22 of B1.
