Ok i have a 99 TL and my niether my front passenger door or rear passenger door will lock, my alarm kept going off the other day bc of the trunk...took it in, said its the multiplex controller is going out and i may need to replace the actualtors...does anyone know how to do this...a diy perhaps, and also i smell gas underneath my car, i had a code p1456...and there arent any loose hoses so what is it? please help

 

I could have sworn that I got DTC P1456 when I accidentally left my gas cap loose. You may want to look there first.

 

Ok well it was a leaking gas cap, found out during vehicle inspection...but what about the multiplex controller, is there a diy ive already searched but ive come up with nothing

 

Never seen a DIY for the multiplex. its a electrical componont so it should be a plug and play though

 

Alright I'll get it tommorow so i will post and let anyone know how it goes..hopefully everything will go smoothly
