• HOLDEN BULLETIN - Pre and Post-Scan of Collision Vehicles Clarification

    - by Holden Motors

    Bulletin number: Aftersales 2017-R3791
    Bulletin date: 16/10/2017

    Summary

    Safety is GM and Holden’s number one priority. A number of important changes have been made with regards to Pre and Post Diagnostic Trouble Code (DTC) scanning. This bulletin replaces 2017-R3750.

    Post-Repair Scans

    Post-Repair Scans must be carried out after the collision repair of every Holden vehicle when the following occurs

    • Action that results in loss of battery-supplied voltage and disconnection of electrical circuits requires that the vehicle is subsequently tested to ensure correct electrical function.
    • Many safety and security-related components, sensors and Electronic Control Units (ECUs) require calibration and/or learns when replaced. These systems must be repaired according to the corresponding GM repair procedures in Service Information (GMSi).

    Pre-Repair Scans

    Holden recommends Pre-Repair Scans. There are several benefits conducting a pre-repair scan for Collision Repairers and Insurers:

    • Collision Repairers and Insurance Companies will have a better understanding of any electrical issues during the estimation process.
    • A more accurate repair estimate can be produced.

    Alert

    • Often batteries have been disconnected by the time a repairer receives a vehicle. Repairers should assess carefully the safety risks associated with reconnection of batteries, before a collision repair is carried out.

    Technology Supported Diagnostic Aids

    The method to correctly identify vehicle diagnostic trouble codes (DTCs) is by using the appropriate GM diagnostic software: GDS2 or Tech 2/Tech2Win. Each can scan a vehicle for all DTCs in one operation. GM diagnostic software is supported by one of the GM approved diagnostic scan tools

    • MDI or a J2534 device.

    GM does not recommend the use of other scan tools and cannot guarantee their accuracy.

    GMSi is the factory source for all diagnostic and repair procedures, wiring diagrams and associated repair information.

    GM Service Programming System (SPS) is the ECU programming application that provides calibration updates and guided learn procedures where required.

    Any repairs performed without using Genuine GM Parts and not following published GM collision repair procedures may result in erroneous DTCs and expose vehicle owners and occupants to unnecessary risk.

    GM collision repair information can be accessed through GMSi or by subscription to www.acdelcotds.com
