I re-read the thread... the OP says failure indicator comes on soon as starting the car... same as me.
Then says adjusting the metal bits in a rear light cluster solved it. But none of these lights are "on" when the car is started.

Does this mean:
1. the bulb failure module "reads" some lights even before they are being used? Maybe ones in the rear (where a driver can't really see the problem while driving, as he could with, say a headlamp out.)

2. the bulb failure module remembers or "latches" the failure, after using the light and module notices an outage of an important bulb, say, a brake light bulb, and doesn't let you forget until the problem is resolved?

At least one of these has to be true, and possibly both. If after starting the car and you haven't used any lights yet for the drive cycle, and you get a failure indicator. ...Right?


Thanks!
