Diagnose faulty low beam - front SAM?
Hi, I've been chasing a non-op driver lowbeam. Is there away to diagnose whether the issue is the ignitor, ballast, or compromised front SAM?

I'm in the process of disassembling the headlamp for a morimoto bi-xenon upgrade. Replacing the bulb did not work. Replacing the ballast has not worked. Next items on the list are replace ignitor - - however, I'm wondering if I can use my iCarsoft MBII to identify a faulty front SAM? Would a faulty front SAM affect only one headlamp?
