Buying Guide
Key considerations when selecting a PSCM
- Vehicle compatibility: Confirm the exact make, model, year, and trim. OEM vs. aftermarket matters for communication with sensors and steering assist.
- Remanufactured vs. new: Remanufactured parts can offer cost savings but may require programming; new OEM units may have straightforward supplier support.
- Programming requirements: Some PSCMs require dealer tools or service information to program correctly. Plan for professional installation if needed.
- Sensor integration: PSCMs rely on inputs from steering angle, torque, and speed sensors. Ensure all sensors are compatible and functional.
- Installation ease: Some units are direct replacements; others need additional mounting hardware or wiring adjustments. Consider your technical comfort level.
- Warranty and support: Check for warranty terms and what coverage applies to remanufactured or second-hand modules.
