Emergency Contact Module: Technical Service BulletinsOnStar(R) - Aftermarket Device Interference Information

INFORMATION Bulletin No.: 08-08-46-004 Date: August 14, 2008

Subject: Information on Aftermarket Device Interference with OnStar(R) Diagnostic Services

Models:2009 and Prior GM Passenger Car and Truck (including Saturn)2009 and Prior HUMMER H2, H3 Models2009 and Prior Saab 9-7X with OnStar(R) (RPO UE1)

This bulletin is being issued to provide dealer service personnel with information regarding aftermarket devices connected to the Diagnostic LinkConnector (DLC) and the impact to OnStar(R) diagnostic probes and Vehicle Diagnostic e-mails.

Certain aftermarket devices, when connected to the Diagnostic Link Connector, such as, but not limited to, Scan Tools, Trip Computers, Fuel EconomyAnalyzers and Insurance Tracking Devices, interfere with OnStar's ability to perform a diagnostic probe when requested (via a blue button call) by asubscriber. These devices also prohibit the ability to gather diagnostic and tire pressure data for a subscriber's scheduled OnStar(R) Vehicle Diagnostic(OVD) e-mail.

These aftermarket devices utilize the Vehicles serial data bus to perform data requests and/or information gathering. When these devices are requestingdata, OnStar(R) is designed not to interfere with any data request being made by these devices as required by OBD II regulations.

The OnStar(R) advisor is unable to definitively detect the presence of these devices and will only be able to inform the caller or requester of theunsuccessful or incomplete probe and may in some cases refer the subscriber/requester to take the vehicle to a dealer for diagnosis of the concern.

When performing a diagnostic check for an unsuccessful or incomplete OnStar(R) diagnostic probe, or for concerns regarding completeness of theOnStar(R) Vehicle Diagnostic (OVD) e-mail, verify that an aftermarket device was not present at the time of the requested probe. Regarding the OVDe-mail, if an aftermarket device is interfering (including a Scan Tool of any type), the e-mail will consistently display a "yellow" indication in diagnosticssection for all vehicle systems except the OnStar(R) System and Tire Pressure data (not available on all vehicles) will not be displayed (i.e. section iscollapsed). Successful diagnostic probes and complete OVD e-mails will resume following the removal or disconnecting of the off-board device.
