reelGOOD 2 Report post Posted April 1, 2011 Hi all, For the life of me I can't find any info on where the flasher relay for the indicators is hiding on an e39. Im wanting to swap it out for a different one so that I can change my bulbs to LEDs without using resistors. Do e39's even have a flasher relay or are the indicators controlled by the LCM in this model? The fact that I cant find any info on it leads me to believe that this is the case. Any info would be much appreciated. Quote Share this post Link to post Share on other sites

It sends a data signal to the instrument cluster, and a clicker in the cluster is activated to make the good old fashioned sound of a flasher relay.

So if thats the case, can the LCM be recoded to change the flash rate of the indicators and stop the hyper flashing you get when LED bulbs are installed?

You can switch off the cold and warm monitoring, depending on model and version of LCM you have Whether it affects the flash rate is something you have to try and see.

jochen 4 Report post Posted April 3, 2011 You can do more in NavCoder when you work with the raw data Procedure: 1. Dump the CodingData to a file 2. Send me the file, include your VIN 3. I can look at the data and tell you what data to change, and send you the command for it Quote Share this post Link to post Share on other sites
