To start, turn off the air bag system, detach the negative
Battery Cable and wait two minutes before you proceed. The service replacement Clock Spring is supplied with a pre-inserted, locking pin. This pin should be in place until the
Steering Wheel is fixed. If you take out the locking pin too early, you must perform the Clock Spring centering so that the SAS and steering system are aligned; otherwise, wrong installation can ruin the Clock Spring and lead to the ESP turning off. Always make sure the steering wheel is straight and locked before you begin. During a Clock Spring change, relay the multifunction switch jumper harness from the previous unit or use a new one. Move the Clock Spring onto the steering column upper shaft and then hook up the three instrument panel wire harness connectors to the back of the Clock Spring case. Attach the Clock Spring onto the steering column lock housing and fix it with three screws going lower right, upper left and finally upper right, tightening the screws to 3 Nm (27 in. lbs.). Fasten the left and right multi-function switches onto the Clock Spring and then set the upper and lower shrouds onto the steering column. Raise the steering column as high as it will go and lock it and then install the steering wheel. Once the rest is done, pull out the plastic locking pin from the Clock Spring rotor and leave the battery negative cable unconnected during testing so that you avoid being injured.
