To All Oldsmobile Dealers:

To reduce the possibility of this occurring dealers are to replace the 107 battery and any battery acid affected component will be cleaned or replaced.

Enclosed with this letter are:

Two Product Campaign Bulletins 85-C-04 Copy of Owner Letter

Dealers with cars to correct will also receive:

Your cooperation in completing this campaign as soon as possible will be greatly appreciated.
On vehicles repaired per the cold startability bulletins (Dealer Technical Bulletins 84-T-20 and 84-T-20A), normal check engine light procedures for trouble code 42 will no longer apply. This trouble code can no longer be set on these vehicles. On vehicles exhibiting the driveability conditions listed below, refer to the following supplemental diagnostic information.

If the supplemental diagnostic procedures do not repair the condition, then the cold start repairs are not the cause and normal diagnostic procedures should be used.
