The Delphi Chassis System ABS VI/TCS service part exchange program is still in effect for certain restricted parts. The parts that are still on restriction are listed in this document. The procedure outlined must be followed when the diagnostics contained within Section 5E1 and 5E2 of the Service Manual lead to the replacement of a part contained on the restricted list.
THE PART REPLACEMENT/RETURN PROCEDURE
1. The Dealership Technician
A. The Dealership Technician is required to diagnose the ABS VI/TCS system using Section 5E1 or 5E2 of the Service Manual and TECH 1 or T100 (CAMS) tools.
B. If the diagnosis leads to the replacement of a restricted part, the Technician must then contact Delphi Chassis System Technical Assistance to verify diagnosis and establish a TAS case using the appropriate phone number as follows:
CHEVROLET 1-800-227-3175
PONTIAC 1-800-523-0203
OLDSMOBILE 1-800-523-0203
BUICK 1-800-523-0203
GM of CANADA 1-800-523-0203
Important:
There are no French operators at these locations. Therefore, GM of Canada Dealers without bilingual personnel should contact their regular "1-800" Technical Assistance Center number.
C. The Technician must have the following information when contacting Delphi Chassis System Technical Assistance:
VIN
Vehicle mileage
Dealer Code
Step-by-step results from the trouble trees used to diagnose the vehicle
2. Replacement Part(s) Orders
A. Upon verification of proper diagnosis involving a restricted part, the TAS Consultant will place the necessary part(s) orders directly to GMSPO or a A.C Delco Service Center.
B. The ordered parts will be shipped to the dealer within 24 hours via GMSPO VIP OVERNIGHT status. The part will be billed with the VIP surcharge and overnight shipping premiums waived.
Important:
Dealers cannot order restricted ABS VI parts directly from GMSPO. If a dealer attempts to order any of the restricted parts directly, the order will be rejected with a message to contact Delphi Chassis System Technical Assistance. A listing of the restricted parts are included in this bulletin.
3. Part(s) Returns
A. System Components Excluding Electronic Brake Control Module (EBCM)
Replacement parts will be packaged in heavy gauge returnable boxes. The box will include a self-adhering return label and a short instruction sheet.
1. To ensure proper and timely core charge crediting, complete the lower half of the provided instruction sheet and include it with the returned part. The following information must be included with all returned parts:
TAS Case Number (assigned by Delphi Chassis System)
VIN
Vehicle Mileage
Dealer Code
Diagnostic Trouble Codes
Copy of Repair Order
Technician's Name and Phone Number
2. Return the replaced part(s) within three (3) days to your servicing parts distribution center.
Important:
Disregard any return label inside service part packaging. All part(s) should be returned through your normal PDC.
3. When your PDC receives the defective part with the proper information, they will issue the appropriate core credit.
B. Electronic Brake Control Module (EBCM)
1. Upon receipt and installation of the replacement EBCM promptly return the removed EBCM to the same A.C. DELCO Service Center that shipped the replacement EBCM.
2. If the removed EBCM core is not returned in a timely manner to the A.C. DELCO Service Center, along with a completed ACD-1078 claim form, the dealer will be charged dealer net or greater for the pre-exchanged unit. Additional ACD-1078 claim forms may be obtained from your vehicle division zone office.
