Detection of faults

Detection of voltage drop at the input

If the input voltage control unit of gas-discharge lamps (9-16) less than normal (except for voltage drop immediately after turning on lights), the control unit switches off in order to protect the gas discharge lamps.

The control unit includes a gas discharge lamp lights again when you resume the normal operating supply voltage.

Fault detection at the input

Upon detection of abnormalities in the output of the system (open or short circuit in wiring harness), the control unit turns off the gas discharge lamps.

If the control of the discharge lamp load due to deviations in the output of the system, the lights remain off as long as the switch of external illumination is again set to the position corresponding to the inclusion of headlights.
