wwest Posted August 7, 2005 Share Posted August 7, 2005 There is an ECU that monitors tail and stop light bulb filament condition. It does this using a small resister in series with the plus side of the 12 volt supply. If one of these sensing resisters should fail or maybe just an ECU connection, the bulbs cannot be illuminated.

bwh414 Posted November 20, 2007 Share Posted November 20, 2007 There is an ECU that monitors tail and stop light bulb filament condition.

I'm having the same problem with my 99 RX after a bad trailer connection blew the tail lights and replacing the bulbs and fuse didn't help. Where is the ECU control unit located, assuming that is what is blown? Thanks, Brian Quote Link to comment Share on other sites More sharing options...
