Hey guys, how you guys doing. I have a small issue with my 2IS and hope you guys may know how to fix it or can provide some advises.
I owned my 2009 IS250 for 2 years already, and currently I installed a Morimoto HID kit with Relay Wire Harness on my low beam. It work perfectly for the last 1.5 months and I do believe it worth to pay that money to get the upgraded.
4 days ago, when I started up my vehicle, I realized that my passenger side low beam suddenly not working, only drive-side fired up. I turned off and on 3 times and it finally came back with both side of lights. So today after school, I decided to do a quick inspect by myself and found out if I unplug the MSF sensor on my cold air intake and start up the vehicle, both side HID fired up and work perfectly, but engine light and other light will pop up which is normal since I unplug the MSF. BUT If I plug-in the MSF and start up the vehicle, then passenger side low beam wont turn on, only drive-side fired up.

So now I am confused and dont really know what is the solution. I personally think It maybe the battery or MSF sensor or the ground of the HID.

Does anyone encountered the same issue before or similar situation before and know how to fix it? I am going to drive it down from Calgary to Vancouver this Saturday and It will takes me almost 12 hour for the road trip. I really need to fix my low beam before the trip.

 

Backtrack and verify your ground is NOT using your MAF sensor for your Morimoto HID ballast ground. Lighting ground should not use engine grounds. It should use chassis ground for lighting.
