Is it necessary to deactivate the air bag and use the 208 exemption when installing a rim-mounted steering control device?
Not typically. Among the commonly used rim-mounted steering control devices (SCDs), NHTSA has not found evidence to suggest that the functioning of the air bag is degraded. Nor is there evidence that rim-mounted SCDs come off during a deployment. So, it does not appear necessary to deactivate the air bag just because you install a steering control device. For additional information on this issue, there are two research reports available from NHTSA. Call Gayle Dalrymple at 202-366-5559.
