To be certain the air bags do not accidentally inflate, disable the SRS, remove the negative
Battery Cable and keep it disconnected for two minutes before installing the Clock Spring assembly. Your new Clock Spring comes with a plastic locking pin already mounted on it; this should be in position until the
Steering Wheel is fitted. In case the locking pin is taken out ahead of time, the Clock Spring centering process is essential to keep the Steering Angle Sensor (SAS) data lined up with the steering system, since improper installation might result in ESP shutdown and Clock Spring damage. Before you do anything, the steering wheel should be directed straight and the locking system set on your steering wheel. In case you have a new Clock Spring, use the multifunction switch jumper harness from the old unit or secure a new harness. Slip the Clock Spring over the steering column shaft from above and join together the three instrument panel connector unto the back of the Clock Spring case. Put the Clock Spring in place over the steering column lock housing and fix it with three screws, lower right first, upper left next and then upper right, checking each one is fixed to 3 Nm (27 in. lbs.) to ensure no ticking sound from steering the wheel. Install the upper and lower shrouds onto the steering column and then put the left and right multi-function switches on the Clock Spring. Lift the steering column all the way and lock it located into position, then attach your steering wheel. And last, detach the plastic locking pin from the Clock Spring rotor to help center the battery, ensuring you don't connect the battery negative cable until the system check is completed.
