Both taillights (for night driving) stopped working. The fuses are okay. I replaced them but they're still not working. Any ideas?
Thanks.
Thanks.

Yep, I have seen the passenger's side MICU go out causing this issue. Here are the wiring diagrams for the system so you can see how the lights work and I have included how to change out the control unit to help fix the problem. Check out the images (below). Please let us know what happens.
