Before servicing the cruise control switch, remove the black wire from the battery to stop the air bag system and wait two minutes for the capacitor to empty. Now, use the right procedures to pull out the air bag module. Remove the screws at the switch-to-steering wheel mounting and take out the switch, before disconnecting the switch's electrical connector. First, insert the switch into the electrical connector, put the switch into place and screw it down with the given torque. Following this, install the air bag module and re-attach the negative battery cable(s).
