Attention: Dealer Service Manager/Warranty Administrator

This bulletin is being revised to offer retail and wholesale service personnel further explanation of the Chevrolet/WINS transitional issues relating to "symptom Diagnosis," "CAMS diagnosis," 1993 and 1994 Labor Time Guides (LTG), and Appendix "D" of the Chevrolet Processing Manual (CPM). Please discard bulletin number 42-05-15 (Section - Warranty Administration).

To begin with, 1993 and prior Chevrolet LTG's were published with "symptom diagnosis" as part of the base time for various electrical and emission labor operations. Chevrolet dealers were allowed to submit additional "CAMS diagnosis" time to specified electrical and emission labor operations found in Appendix "D" of the CPM; warranty files would accommodate this combination without the need for excessive authorization.

Effective with the 4/15/94 Revision to the 94 LTG, "symptom diagnosis" was eliminated from the base time of most electrical and emission labor operations. In its place, dealers were advised, via the LTG forward section entitled "Diagnosis," to use the new add condition "variable diagnosis." Also, effective with the 04/15/94 revision, labor operation J9997 "CAMS diagnosis" time was eliminated.

Dealers were advised of the elimination of "CAMS diagnosis" time, labor operation J9997, in Warranty Administration bulletin number 420505 dated 4/94. This bulletin also advised dealers to begin using "variable diagnosis" in place of the "CAMS diagnosis"; it did not specifically read that "variable diagnosis" also replaced "symptom diagnosis," but should have. As a transitional item, dealers could continue to add the "CAMS diagnosis" time to the labor operations specified in Appendix "D" of the CPM up until 09/14/94. As of 09/15/94, dealers were no longer allowed to use the "CAMS diagnosis" time for 1994 and future model years. Claim processing procedures for 1993 and prior model years remained unaffected by bulletin 420505.

In July of 1994, warranty administration bulletin 480501, for all divisions except Buick, introduced "customer concern not duplicated/verified labor operations" and announced that "CAMS diagnosis" time was discontinued for 1989 and future model years; this was incorrect for Chevrolet Dealers. To correct this, Chevrolet "CAMS diagnosis" misinformation, Warranty Administration bulletin number 420510 dated 08/94, reminded Chevrolet Dealers that on 09/14/94 "CAMS diagnosis" time was discontinued for 1994 and future model years, not 1989 and later.

Warranty Administration bulletin number 42-05-15, dated 12/94, advised Chevrolet Dealers that "CAMS diagnosis" time for 1993 and prior model years was discontinued; which is correct. In its place, dealers were advised to use "variable diagnosis" and would be able to do so without the need for authorization for up to 0.3 hrs; this is not correct. This bulletin is being revised to advise dealers that for 1993 and prior model years "symptom diagnosis" is included in the base time of various labor operations and that any time in "other labor hours" will require an "E" authorization.
