Notice: Electrostatic discharge (ESD) can damage many solid-state electrical components. ESD susceptible components may or may not be labeled with the ESD symbol. Handle all electrical components carefully. Use the following precautions in order to avoid ESD damage:

•	Touch a metal ground point in order to remove your body's static charge before servicing any electronic component; especially after sliding across the vehicle seat.

•	Do not touch exposed terminals. Terminals may connect to circuits susceptible the ESD damage.

•	Do not allow tools to contact exposed terminals when servicing connectors.

•	Do not remove components from their protective packaging until required to do so.

•	Avoid the following actions unless required by the diagnostic procedure:

-	Jumpering or grounding of the components or connectors.

-	Connecting test equipment probes to components or connectors. Connect the ground lead first when using test probes.

•	Ground the protective packaging of any component before opening. Do not rest solid-state components on metal workbenches, or on top of TVs, radios, or other electrical devices.

3. Slide the immobilizer control unit toward the steering wheel until it slides off its mounting bracket.
4. Disconnect the electrical connectors from the immobilizer control unit (1).

After replacing the immobilizer control unit, the keys must be re-authorized using the key coding procedure. Refer to Programming Additional Keys . Also, the electronic control module (ECM) identification (ID) code must be reset. Refer to Programming Theft Deterrent System Components .
