Safety Recall: Ignition Switch Key Interlock (Supersedes 03-034, dated December 23, 2003)
Updated information is shown by asterisks and black bars.
BACKGROUND
Limited batches of an ignition switch component do not have sufficient surface hardness. An ignition switch with this defective component may wear excessively, making it possible to remove the key when the shift lever is not in Park. If the driver does not set the parking brake when parking, the vehicle could roll, and a crash could occur.
VEHICLES AFFECTED
Not all vehicles within the VIN ranges are affected by this recall. Before beginning work on a vehicle, verify its eligibility by checking at least one of these items:
^ The customer has a notification letter.
^ The vehicle is shown on your campaign responsibility report.
^ The vehicle is shown as eligible on an iN VIN status inquiry.
In addition to the bulleted verification items, check for a punch mark above the sixth character of the engine compartment VIN. A punch mark in that location means the key interlock has already been repaired.
Some vehicles affected by this recall may be in your used car inventory. According to federal law, these vehicles cannot be sold or leased until they are repaired. To see if a vehicle is affected by this campaign, do a VIN status inquiry before selling it.
Some of the vehicles involved in this campaign are affected by other campaigns and may not have been repaired. As a convenience to your client, do a VIN status inquiry, and complete all outstanding campaigns on the same visit.
CUSTOMER NOTIFICATION
All owners of affected vehicles will be sent a notification of this campaign. An example of the customer notification is shown in this service bulletin.
CORRECTIVE ACTION
Inspect the interlock function of the ignition switch, and depending on whether or not the key can be removed, install Key Interlock Repair Kit A or Key Interlock Repair Kit B.

INSPECTION PROCEDURE
*NOTE:
^ Before attempting any repairs, you must thoroughly understand this service bulletin.
^ Parts, tools, and repair procedures for 1997 CLs are still under development. DO NOT use the information in this service bulletin to inspect/repair 1997 CLs.*
1. Remove the steering column covers. Refer to section 17 of the appropriate service manual.
2. Remove and discard the plastic cover from the ignition switch key interlock solenoid.
3. Note the position of the interlock solenoid plunger; you'll need to install it the same way.
4. Remove and discard the screw from the interlock solenoid. Keep the solenoid attached to its electrical connector.
NOTE:
^ Be careful not to lose the solenoid plunger; it slides out easily.
^ Keep the plunger free of dirt or grease while it's removed from the solenoid.
5. Note the position of the interlock lever spring; you'll need to install the new spring the same way. Also, measure the installed height of the interlock lever pin with vernier calipers. This measurement will be used in both repair procedures.
6. Attach the slide hammer to the interlock lever pin, and use it to remove the pin. Discard the pin, the lever, and the spring.
7. Insert the key into the ignition switch, turn the switch to the ACCESSORY (I) position, and install the gauge block.
8. With the gauge block fully seated, try to turn the ignition switch to the LOCK (0) position.
^ If you cannot turn the switch to the LOCK (0) position, install Key Interlock Repair Kit A (see REPAIR PROCEDURE A).
^ If you can turn the switch to the LOCK (0) position, install Key Interlock Repair Kit B (see REPAIR PROCEDURE B).
