Effective May 1, 2008, changes have been implemented which will enable TAC to provide more timely and consistent service.
A most important requirement is that technicians MUST complete the key steps of Strategy Based Diagnosis (SBD) BEFORE placing the call to TAC. This information will be REQUIRED at the time of the call:
1. Complete work order, including VIN and details of customer concern.
2. Amount of days the vehicle has been down.
3. Attempt to duplicate customer concern.
4. All DTCs, values and measurements recorded and diagnosed.
5. Search all of SI for diagnostic information, bulletins, and PIs.
IMPORTANT: If you are not prepared at the time of the call, you will be requested to use SBD before calling back.
TIP: For more information, refer to these preparedness documents:
- Policy and Procedures, section 5.3.1
- SI Document 1957622, Strategy Based Diagnosis
- Bulletin 01-00-89-010G, Use of Customer Concern Verification Sheets, Comeback Prevention, GM TAC Form, Strategy Based Diagnosis (SBD), Intermittent Concerns Diagnostics, Repeat Repair Log
