Ignition Switch

REMOVAL & INSTALLATION



Both the electrical portion of the ignition switch and the key/lock portion may be replaced without removing the housing or bracket holding them. The bracket holding the ignition switch assembly is held to the column by shear-head bolts (the heads intentionally break off upon final torque installation). About the only time the bracket must be removed would be if the steering column or tube must be replaced. In the event that the bracket must be removed, the headless bolts must be center-punched, drilled and removed with a screw extracting tool.


CAUTION
Work must NOT be started until after 90 seconds from the time the ignition switch is turned to the LOCK position and the negative battery cable is disconnected from the battery. The SRS is equipped with a back-up power source so that if the work is started within the 90 seconds of disconnecting the negative terminal, the SRS may be deployed.

  1. Disarm the SRS system. For additional information, please refer to the following topic(s): "CHASSIS ELECTRICAL," "SRS System." See .
