SERVICE MANUAL UPDATE
Subject:
Revised OnStar(R) Antenna Coupling Replacement Procedures
Models:
2000-2002 Passenger Cars and Trucks with Glass Mounted Antenna
This bulletin is being revised to add the 2002 model year and revise the service procedures. Please discard Corporate Bulletin Number 01-08-46-006
(Section 08 - Body and Accessories).
This bulletin is being issued to revise the OnStar(R) inner and outer antenna coupling replacement procedures in the Cellular Communication sub-section
of the Body and Accessories section in the appropriate Service Manual. Please use the following to replace the existing information in the Service
Manual.
This information has been updated within SI2000. If you are using a paper version of this Service Manual, please mark a reference to this bulletin on the
affected page in the Cellular Communication sub-section of the Service Manual.
Coupling Replacement - Antenna Inner
Removal Procedure
Important:
Use the described adhesion promoter to assure adequate bonding of the coupling to the glass. To obtain maximum adhesion between the new mobile
antenna couplings and the glass surface, the couplings and the glass must be kept dry and above 15°C (60°F) during the installation and for 6-8 hours
immediately following the installation. Otherwise the new couplings may come off. Also, disregard the drying or curing time information listed in the
instructions included in the replacement antenna coupling kits. In the near future, those instructions will be updated with the drying or curing times
listed in this bulletin.
^
Do not attempt to reinstall the original cellular couplings using any type of glue, adhesive tapes, etc. Doing so may eliminate the cellular signal
transfer through the glass and reduce the maximum performance of the system, including the air bag deployment notification.
1.
Disconnect the coaxial cable from the inner coupling of the mobile communication antenna.
Notice:
If you use a razor blade or other sharp tool in order to remove the adhesives or foreign objects from the inside of the rear window, use the blade
carefully. Damage to the grid lines may result.
Use a small, wide-bladed plastic tool to cut the double back tape material while lifting up on the inner antenna coupling.
