Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Variable Assist Power Steering (VAPS) Module
The VAPS module (if equipped) uses the SCP communications network for communication with the diagnostic tool and other modules on the SCP communications network. The VAPS module controls the level of power steering assistance available to the driver based on vehicle speed.
Check the SCP communications network circuits between the VAPS module C2231a and the DLC C251. The total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the SCP communications network, damage to the DLC C251, or damage to the VAPS module C2231a.
For additional VAPS module information, refer to STEERING SYSTEM-GENERAL INFORMATION .
