2003 Tahoe Unknown Driver
I have a 2003 Tahoe that is displaying Unknown Driver on the dash. Battery died from parasitic draw from aftermarket head unit and now the Unknown Driver message. I’ve replaced the battery but when I try to start the engine, it turns over but immediately dies. Must be a security feature but the security light isn’t on on the dash. If I just turn the key to power the only electronics that work is the climate control and radio. I’ve tried to relearn the key, 10min on - 5 sec off three times; I’ve tried disconnecting the battery for 30 min; I’ve tried touching the two battery terminals together; I’ve even replaced the seat memory module; nothings worked. Could it be the ignition itself? Any ideas????
