The Pass Key / VATS (Vehicle Anti-Theft System) Control Module on a 1989 Corvette is an electronic device that is designed to prevent unauthorized access to the vehicle by disabling the engine’s ignition system. The module is part of the anti-theft system that was introduced in the 1980s to help reduce the number of car thefts.

The Pass Key / VATS Control Module works by using a special key with a built-in resistor, which is called a “VATS key”. When the key is inserted into the ignition switch, the VATS module reads the resistance of the key and compares it to a pre-programmed value. If the resistance of the key does not match the programmed value, the module will disable the ignition system, preventing the car from starting.

In addition to preventing the car from starting, the Pass Key / VATS Control Module can also sound an alarm or activate other security features if it detects an attempted theft or break-in. The system can be programmed with multiple keys, allowing multiple drivers to access the vehicle.

If the Pass Key / VATS Control Module fails or malfunctions, it can result in the ignition system being disabled, preventing the car from starting. A qualified mechanic or dealership can diagnose and repair any issues with the Pass Key / VATS Control Module, which may involve reprogramming the module or replacing it entirely.

Overall, the Pass Key / VATS Control Module helps to improve the security of the 1989 Corvette by preventing unauthorized access and reducing the risk of theft or break-ins.
