Internal Fault

Internal fault

Replacing the component
The central electronic module (CEM) has detected that the left-hand gas discharge lamp module (GDL) has an internal fault.
If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults can be caused by interference at start up of the gas discharge lamp module (GDL) or may be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs. If the fault recurs, replace the left-hand gas discharge lamp module (GDL).
If the fault is permanent, replace the left-hand gas discharge lamp module (GDL).
If the gas discharge lamp module (GDL) is replaced, the position sensor must be calibrated.
Remedy as necessary.
