2000 Saturn SL2 Won't Start with U1000 Code: Loss of Communication Diagnosis
Hello, I own a 2000 Saturn SL2 that won't start, and the security light is illuminated. A technician scanned the vehicle and retrieved fault code U1000, indicating 'loss of communication'. I'm wondering if this code directly prevents the car from starting. Is it possible for a U1000 error to cause a vehicle to fail to start?
Code U1000 is commonly reported on GM vehicles and typically indicates a loss of communication between the powertrain control module and the body control module. For detailed information, refer to https://www.obd-codes.com/u1000.
