Now that I think of it though the gas gage is very funky most times, like tonight I filled the tank and it stays at 3 quarts of a tank for awhile. Sometimes never goes to the fill marker.I will do that but the lights go out and zero battery drain when I pull the 30 amp fuse to the radio. I also have already threw a loop on the amp and radio and still won't go to sleep, yes I even pulled the fuse and recoded the car saying it didn't have them. This thing is crazy lol.
Yeah that's what I have been doing! I have been going crazy I have done the following..So if the battery drain goes away with the radio powered down thats where I would focus my attention.
no the 5 amp fuse for the navigation is out because it's coded out of the car. I always pull the 30amp fuse when I'm leaving the car by itself for a few hours so it doesn't drain the battery. The 30amp fuse is sound system.You talking about fuse 5 next to the media rack that feeds the bose amp?
Ok I have an update!, I just did what you asked previous, I pulled the 5amp fuse from the instrument cluster and locked the car and with in minutes the light in the dash and shifter went to sleep.... So it seams like it is the instrument cluster problem.. My question is why would the car go to sleep with the radio fuse unplugged? Is it maybe the car really isn't going to sleep but the battery isn't drawing because the whole sound system cannot pull from it? Maybe the sound system is after th instrument cluster in the sequences? Thanks your very helpful I must say.You talking about fuse 5 next to the media rack that feeds the bose amp?
I agree the only problem is by wiring a relay I would possibly get DTCs all over? When I did pull the cluster fuse I got DTCs for a tone of things?Well if it is indeed the cluster keeping the can bus active it may indeed keep the amp switched on and it's draining the battery,
Monitor it for a week or so with pulling the cluster fuse each time and leaving the amp fuse in and see if it is indeed the cluster that's keeping it awake and causing the drain.
If it is you me looking at replacement or doing as Jack had said in another thread about wiring in a relay that when terminal 15 is off it deactivates the relay the you wiring into to power to the cluster, so it's basically turned off by the relay so the cluster can't keep the can bus active
So how do I keep it active after I pull it? Don't lock the car?The reason you got tonnes of errors is because the fuse you pulled also powers the gateway, so to be sure you actually looking at a fault with the cluster you need to unplug it leaving the gateway still active, you will get errors for the cluster being missing but everything else should behave better.
OK I have an update I unplugged the cluster and the Car doesn't go to sleep when I pull the 5Amp fuse the car goes to sleep but battery still seams to drain.. I then decided to try something else I left the cluster plugged and 5amp fuse to cluster plugged in. I also left the 30Amp sound system fuse in and unplugged the satellite radio power plug and car went to sleep, i also pulled the 5Amp fuse for satellite radio out and car went to sleep, i then plugged all back in and unplugged the fm radio and car fell asleep lol.. my next steep was to code the car to not have the satellite radio but I'm having troubling doing so.. in the can19 install list they have digital radio, analog radio, I tried unchecking both and nothing codes it out, there is a listing for satellite tuner but thats unchecked, when i check it i then get a DTC saying that module is incorrectly coded? please help maybe tell me the best way to code the satellite radio not of can so I can trouble shot it... thanks for all the help...If you leave the fuse in situ but unplug the instrument cluster from the back that should tell you if its the cluster or something else on the can bus thats keeping it awake
