Steering Wheel

Disabling the SIR system while removing the inflator module should be the first step to replace the steering wheel. Unplug the steering wheel control electrical wiring connector while you unscrew the steering wheel retaining nut. You can remove the steering wheel by installing the Steering Wheel Puller Legs (J 42578) and the Steering Wheel Puller (J 1859-A) onto it before using the tools to detach the wheel. Remove both the Steering Wheel Puller Legs (J 42578) along with the Steering Wheel Puller (J 1859-A) after completing wheelchair extraction. Start by disconnecting controls and control harnesses from the steering wheel when they are present. The controls must be installed with their harnesses to the steering wheel before running wires through the steering wheel. Anchor down the steering wheel after plugging in the steering wheel control electrical connector. Screw in the steering wheel nut while applying torque to 41 N.m (30 lb ft). You should install the inflator module after which you can enable the SIR system.

The SIR system needs to be disabled before starting replacement of the steering wheel. Start by taking apart the inflator module and unplug the steering wheel control electrical connector. Mount the J 1859-A Steering Wheel Puller (J 1859-A) and J 42578 Steering Wheel Puller Legs (J 42578) on the steering wheel while making sure the J 1859-A Steering Wheel Puller (J 1859-A) engages the steering wheel first. The tools enable the user to separate the steering wheel before removal. First remove steering wheel controls together with their control harness if your model has them. Install controls together with their control harness at the steering wheel while making sure the wire routing passes through it correctly. Place the steering wheel in position while reattaching the steering wheel control electrical connector. Secure the steering wheel with the nut at a torque rate of 41 Nm (30 ft. lbs.). You must finally install the inflator module and activate the Restraint System.
