Headlight Malfunction

sur135 · 08-09-2018, 11:37 PM

Hi All- Pretty new to this. So I received these 4 errors on the dash. Confident it is due to water getting into the headlight and condensation, which has already dried up. High and low beams working fine. Just for the driver side headlight, the DRL's do not light up nor does the turn signal light (flickers fast on the dash only). Do I need both a new ballast module, footwell module, or even headlight control module? Would Carly be able to code them after replacing? Any help would be appreciated!

I had this happen, it ended up being the headlight module.

When you get numerous headlamp faults all at the same time on one headlamp its usually a failed headlamp module, the one that plugs in like an old Nintendo cartridge.

Carly cannot program and encode a new module, you will need a legitimate tool like ISTA/P for this. Used modules are readily reprogramable to a new vehicle either.
