Why Bypassing VATS Directly is Risky:
* Security: Bypassing VATS completely defeats the anti-theft system, leaving your car vulnerable to theft.
* Electrical Damage: Improperly wiring power to the fuel pump could overload circuits, damage the pump itself, or even cause a fire.
* Other System Issues: The VATS system is integrated with other parts of the car's electronics. Bypassing it might trigger error codes or cause other systems to malfunction.
How to Troubleshoot and Fix the Problem:
The correct approach is to diagnose and fix the VATS problem, not bypass it. This usually involves:
1. Check the Key: Ensure your key is properly programmed for your vehicle. A worn or damaged key is a common cause of VATS issues. Try a known good key if possible.
2. Inspect the VATS Components: This might include:
* Passlock Sensor Ring: Located on the steering column, it reads the key's transponder chip. Check for damage or corrosion.
* Passlock Module: This module receives the signal from the sensor ring and controls the fuel pump relay. Inspect for damage or loose connections. The location varies by year and model.
* Fuel Pump Relay: Check the relay itself for proper operation. You might try swapping it with a known good relay of the same type. (Always disconnect the negative battery terminal before working with electrical components).
3. Use a Diagnostic Scanner: A professional-grade scan tool can read diagnostic trouble codes (DTCs) related to VATS. These codes will pinpoint the exact problem.
4. Professional Assistance: If you're not comfortable with car repair, take your Cadillac to a qualified mechanic or dealership. They have the diagnostic tools and expertise to properly diagnose and repair VATS problems.
In short: Don't try to force power to the fuel pump. Fixing the underlying VATS issue is the only safe and reliable solution. Attempting a bypass is dangerous and could result in significant damage to your vehicle.
