I know my HFL/BT doesn't work. I'm sure I need to fix that. I also have a parasitic draw on my battery that bounces between .5 & .4 & traces back to fuse 6 interior circuit for interior lights & the MICU. Does anyone know if the HFL can cause that draw from ECU/MICU? I can't find good wiring diagrams and I know these MICU systems don't diagnose as easily as a normal electrical circuit. My dealer wants close to $700 for a new ECU my MICU. Does baking the HFL really work?

 

It worked for me! I figured since it hasn't worked in awhile I would try it anyway.

Post #538 & 543 are how/what I did, like others.....

I do know that HFL has a parasitic draw, but that's it. I had mine unplugged for months before baking it, just to avoid having a dead battery (unexpectedly).


BTW-Welcome to Azine!

 

HFL definitely causes a draw.

 

Unplug the unit and see what happens
