If I bypass my telematics control unit with a fiber obtic, could it still drain my battery? I have been experiencing battery drain and I had a SOS light malfunction on my dash along with popping speakers.. I bypassed the TCU and the speakers stopped popping and the light went away. I am still getting battery drain.. can it still cause battery drain if it's bypassed? Also sometimes my car will not work to be jumped… I'll leave it hooked up to another car for 20 minutes and it still won't be jumped. Could it just be a bad battery? My tail lights will also not turn off and my key phone will sometimes not pop out when I push it in and there will be a weird clicking noise. Please help guys I really could use it.
