[QUOTE="jarance, post: 351631, member: 21"] bro, most of the bulbs (alarm) will light up when you first turn the ignition to position "1". You can remove individual bulb and test it with an ohm meter or apply voltage. The pixel dots cannot be tested without connecting to the EWS module.. did you have a chance to look at the wiring diagram attached earlier. BTW, you cannot drive a pixel dots individually. It works by matrix switching. [IMG]http://i122.photobucket.com/albums/o271/pbjy/AFM/Passive_and_Active_Matrix_LCDs.jpg[/IMG] [/QUOTE]
