Steering Column

The first step for servicing the deployable steering column requires testing the SRS dependency then opening all SRS devices outdoors at a minimum distance of 9.14 meters (30 feet) away while using hearing protection due to deployment noise. Access to the electrical connector can be gained by either lowering down or fully removing the deployable steering column from its instrument panel position. The wiring pigtail must be removed from the original vehicle harness when deploying the column except for at least 4 inches of wire remaining available for work. Laboratory personnel must first remove the wire sheathing before exposing the cut wire ends. Two 20-gauge wires with minimum 9.14 meters (30 feet) length each should be stripped at both ends to make a jumper harness. Joint the two wires at the beginning part of the jumper harness. The deployable steering column wiring should get its corresponding wires by attaching the jumper harness ends while applying insulation to close any contact points. Structure the jumper harness at least 9.14 meters (30 feet) away from the column. A completed deployment of the steering column requires connecting the ends of the jumper harness wires to a 12-volt battery following their detachment from each other. The personnel must wait for a minimum of 10 minutes after deployment before approaching the deployed steering column. They must follow standard scrapping procedures to dispose of it correctly.
