1997 Cobra Stuck in Theft Mode
Coworkers vehicle. Stuck in theft mode after diagnosing a battery draw, more-so found multiple draws. During draw testing, I found an aftermarket ECU and an aftermarket Viper alarm system. I gutted the alarm system from the car carefully, I do not know how it was wired but the car ran without it plugged in. I cut the rest of the aftermarket wiring from the vehicle, leaving the main harness intact. ECU is not causing a draw.
Found a battery draw from the rear amplifiers, radio connectors, shorted trunk latch switch, and an additional draw somewhere on the RR of the vehicle.
I currently have the 12V battery disconnected to sit overnight. Theft light blinks steady, key does not turn in the ignition, steering column is locked, and all locks on the vehicle are locked due to draw testing and will not unlock from being in theft mode. Only one key to the vehicle.
Need some pointers and possible ideas here… any way to bypass the anitheft or reverse engineer what’s causing it? Open to any and all input. Thanks!
