GM Announces Diagnostic Time Allowance Changes

As a result of technician feedback, GM is implementing a new Diagnostic Time Strategy. This new process is designed to provide adequate time for technicians to diagnose the most difficult conditions. (Fig. 11)

Increase in Diagnostic Time

从7月1日开始，诊断时间从平面0.3变为0.1-1.0次超过1,100次劳动力运营。增加了对劳动力的增加，传统上具有最多的其他劳动时间（OLH）（例如电气和模块诊断）的百分比。其他业务也已被审核。例如，R1234YF空调系统的抽空和充电的劳动时间从0.5小时增加到1.2小时。

此外，在易于识别的93次劳动业务上拆除了诊断时间，例如涉及修剪和灯泡更换的人。如果在这些项目上需要额外的劳动时间，则应遵循当前的OLH过程。

Claim Submissions

Variable diagnostic time of 0.1–1.0 can be submitted in the Diagnosis Time field instead of the 0.3 time. (Fig. 12) Technicians are required to punch on and punch off for all diagnostic time. As always, diagnostic time must include supporting documentation, including proper cause and correction comments.

Labor operations aside from modules not in the following categories remain at 0.3:

54 – Power and Signal

40 – Engine Propulsion

34 – Driver Information and Entertainment

20 – Body Systems

84 – Transmission

64 – Safety and Security

50 – Hybrid

Any additional time needed for operations that did not have an increase applied should follow the current OLH process. U.S. dealerships can self-authorize up to 0.5 hours of OLH. Potentially, a claim submission could be approved without review with up to 1.5 hours of diagnostic time, including the OLH.

有关诊断时间和OLH提交的其他信息，请参阅公告＃18-NA-263。

Labor Time Guide

The Labor Time Guide (LTG) will reflect these new changes. There will be two new add times in the LTG — one for U.S./Canada indicating 0.1–1.0 and another that excludes U.S./Canada and reflects the current 0.3 for other Regions/Countries. (Fig. 13)

The benefits to the new Diagnostic Time Strategy are expected to be many:

• 增加车辆固定right the first time
• Increased customer satisfaction
• Less repeat repairs
• A reduction in excessive warranty part replacements.
