OPEN CIRCUIT Connect Adaptive front lighting module to 1 Connect Adaptive front lighting module to 2 Ignition switch in position II. 3 SWITCH ON dipped beam. 4 Measure the voltage between front headlamp LCD23B (GN/OG), wiring harness side and ground. 5 Measure the voltage between rear headlamp LCD23D (GN/OG), wiring harness side and ground. 6 Is a voltage of 5 Volts measured in both cases? GO to B17 . No - If no voltage is measured during both of the GO to B16 . - Is a voltage of 5 Volts measured during just one B16: RULE OUT THE ADAPTIVE FRONT LIGHTING MODULE AS A POSSIBLE CAUSE OF Ignition switch in position 0. 1 Disconnect Adaptive front lighting module from 2 Measure the resistance between adaptive front LCD23G (GN/OG), wiring harness side and front 3 Is a resistance of less than 2 Ohms registered? RENEW the adaptive front lighting module. CHECK No LOCATE and RECTIFY break in circuit between
