This bulletin is being revised to add model years. Please discard Corporate Bulletin Number 02-08-46-006B (Section 08 - Body and Accessories).

A small number of the above-mentioned vehicles may exhibit a condition in which the vehicle reports an inaccurate location to the OnStar(R) CallCenter. This condition can only be identified via a button press to the OnStar(R) Call Center by the customer. Call Center personnel will be able toidentify this inaccurate location condition. Customers will then be notified through the mail by OnStar(R) if their vehicle exhibits this condition. Oncethis condition has been identified OnStar(R) will instruct the customer to return to the dealership to have this condition corrected.
It is not necessary to reconfigure the vehicle after the following procedure.

In order to correct this condition you must cycle power to the OnStar(R) system. This can be done by either removing the fuses powering the OnStar(R)system or disconnecting the OnStar(R) module (VCIM) from the vehicle. As a last resort you can disconnect the vehicle's battery.
The power needs to be removed from the system for approximately 15 minutes.

After completing this procedure the vehicle should be taken to an area with an unobstructed view of the sky. The vehicle should be kept running forapproximately 10 minutes to allow the vehicle to reacquire the global positioning system (GPS). Then contact the OnStar(R) Call Center via the blueOnStar(R) button and ask the advisor to verify the GPS position.

If the OnStar(R) advisor still has an inaccurate GPS location refer to the Navigation Systems and Cellular Communications sub-sections in the ServiceManual in order to diagnose and repair the concern. If the normal diagnostics lead to module replacement you will need to contact Technical Assistance(TAC) and choose the OnStar(R) prompt. GM OnStar(R) TAC will assist in the diagnosis and if appropriate order a replacement part. Replacement partsare usually shipped out within 24 hours and a pre-paid return package label will be included for returning the faulty part.

This bulletin is being revised to add the 2008 model year, warranty information and to provide GPS signal recovery steps (under Dealer Action heading)to do PRIOR to determining if the VIU/VCIM needs replacement. Please discard Corporate Bulletin Number 02-08-46-007B (Section 08 - Body &Accessories).

If the vehicle currently has analog-upgradable OnStar(R) hardware, then the customer should be made aware of the digital upgrade program per the latestversion of Service Bulletin # 05-08-46-006. Any analog OnStar system that is not upgraded prior to the end of 2007 will be deactivated due to theupcoming phase-out of the analog cellular network in the U.S. and Canada. If the vehicle has recently been upgraded or has had a service replacementunit installed, this bulletin may not be applicable.

Certain 2001-2008 model year vehicles equipped with OnStar(R) may exhibit a condition with the Global Positioning System (GPS) that causesinaccuracies in the GPS clock. The GPS system is internal to the OnStar(R) Vehicle Interface Unit (VIU) or the Vehicle Communication InterfaceModule (VCIM). This inaccuracy can result in a symptom where the OnStar(R) Call Center is unable to obtain an accurate GPS signal, hands-FreeCalling minutes expire prematurely and/or the inability to add Hands-Free calling minutes.
Customer Notification

OnStar(R) will notify the customer by mail with instructions to contact their dealership service department.
Dealer Action
Not all vehicles will require VIU/VCIM replacement.

The GPS signal in some vehicles may be recoverable. To determine if the signal is recoverable, simply connect the Tech2(R) and using the GPSinformation data display option, observe the GPS date and time. If the date/time stamps are equal to a date approximately 19 years in the future, the GPSclock has exceeded its capacity and the VIU/VCIM will need to be replaced. If the date/time stamp is in the past or near future, the GPS clock has simplygenerated an inaccurate value and may be recoverable by performing the following power-up reset.

To initiate a power-up reset, battery voltage (batt. +) must be removed from the VIU/VCIM. The preferred methods, in order, of initiating the reset areoutlined below.

> Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Emergency Contact Module > Component Information > Technical Service Bulletins >

Savana 1/2 Ton Van V6-4.3L VIN W (2001)

Remove the fuse that supplies Battery positive (Batt. +) voltage to the module (refer to the applicable Service Information schematics for the appropriatefuse).
The next preferred method is to remove the connector to the OnStar(R) unit that Batt + is contained.

The least preferable method is to remove the negative terminal of the vehicle battery. This will not only initiate the power-up reset, but it may also resultin the loss of radio presets and other stored personalization information/settings in other modules as well.

After initiating the power-up reset, the GPS data will be set to the defaulted date and time and will require an acquisition of the GPS signal in order togain the proper date and time.

Acquiring the GPS signal requires running the vehicle in an open/unobstructed view of the sky. First, contact OnStar(R) Technical Support by pressingthe blue button. Allow the OnStar(R) Technical Advisor to activate the GPS recovery process. This should take approximately 10 minutes. Continue to

monitor the Tech2(R) for the current time and date. REMINDER - Keep in mind that the time displayed on the Tech2(R) is in Greenwich Mean Time(GMT) and the offset is based on the time zones relationship to GMT.

If replacement of the VIU/VCIM is necessary, you MUST reconfigure the OnStar system. Failure to reconfigure the system will result in an additionalcustomer visit for repair. OnStar VIU, Generations 2 and 3, will require the technician to press the blue OnStar button to reconfigure the vehicle withan OnStar advisor.

OnStar(R) VCIM, Generations 4-7 will require the technician to reconfigure the vehicle with the use of the TIS2WEB and SPS applications (pass thruonly), along with the Tech2(R).

The configuration and set-up procedure is a two-step process that must be completed step-by-step without interruption or delay in between each step.This procedure enables an automated activation without a button press by the technician to the OnStar(R) Call Center. Following this procedure, it maytake up to 24 hours for all OnStar(R) services to be fully activated.
How to Order Parts

If the OnStar(R) GPS date/time stamp is non-recoverable and the unit needs to be replaced, dealers in the U.S. should contact Autocraft Electronicsselect the catalog item that contains this bulletin number. Canadian dealers should contact MASS Electronics.

Dealers DO NOT need to call the GM Technical Assistance Center (TAC) for replacement approval. Autocraft Electronics and MASS Electronics willbe responsible for verifying that the subject vehicle is a candidate for a replacement VIU/VCIM.

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.

This bulletin is being revised to add the 2008 model year, warranty information and to provide GPS signal recovery steps (under Dealer Action heading)to do PRIOR to determining if the VIU/VCIM needs replacement. Please discard Corporate Bulletin Number 02-08-46-007B (Section 08 - Body &Accessories).

If the vehicle currently has analog-upgradable OnStar(R) hardware, then the customer should be made aware of the digital upgrade program per the latestversion of Service Bulletin # 05-08-46-006. Any analog OnStar system that is not upgraded prior to the end of 2007 will be deactivated due to theupcoming phase-out of the analog cellular network in the U.S. and Canada. If the vehicle has recently been upgraded or has had a service replacementunit installed, this bulletin may not be applicable.

Certain 2001-2008 model year vehicles equipped with OnStar(R) may exhibit a condition with the Global Positioning System (GPS) that causesinaccuracies in the GPS clock. The GPS system is internal to the OnStar(R) Vehicle Interface Unit (VIU) or the Vehicle Communication InterfaceModule (VCIM). This inaccuracy can result in a symptom where the OnStar(R) Call Center is unable to obtain an accurate GPS signal, hands-FreeCalling minutes expire prematurely and/or the inability to add Hands-Free calling minutes.
Customer Notification

OnStar(R) will notify the customer by mail with instructions to contact their dealership service department.
Dealer Action
Not all vehicles will require VIU/VCIM replacement.

The GPS signal in some vehicles may be recoverable. To determine if the signal is recoverable, simply connect the Tech2(R) and using the GPSinformation data display option, observe the GPS date and time. If the date/time stamps are equal to a date approximately 19 years in the future, the GPSclock has exceeded its capacity and the VIU/VCIM will need to be replaced. If the date/time stamp is in the past or near future, the GPS clock has simplygenerated an inaccurate value and may be recoverable by performing the following power-up reset.

To initiate a power-up reset, battery voltage (batt. +) must be removed from the VIU/VCIM. The preferred methods, in order, of initiating the reset areoutlined below.

> Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Emergency Contact Module > Component Information > Technical Service Bulletins >

All Technical Service Bulletins for Emergency Contact Module: > 02-08-46-007C > Nov > 07 > OnStar(R) - Loss of GPS Signal/Hands Free Issues > Page 58

Savana 1/2 Ton Van V6-4.3L VIN W (2001)

Remove the fuse that supplies Battery positive (Batt. +) voltage to the module (refer to the applicable Service Information schematics for the appropriatefuse).
The next preferred method is to remove the connector to the OnStar(R) unit that Batt + is contained.

The least preferable method is to remove the negative terminal of the vehicle battery. This will not only initiate the power-up reset, but it may also resultin the loss of radio presets and other stored personalization information/settings in other modules as well.

After initiating the power-up reset, the GPS data will be set to the defaulted date and time and will require an acquisition of the GPS signal in order togain the proper date and time.

Acquiring the GPS signal requires running the vehicle in an open/unobstructed view of the sky. First, contact OnStar(R) Technical Support by pressingthe blue button. Allow the OnStar(R) Technical Advisor to activate the GPS recovery process. This should take approximately 10 minutes. Continue to

monitor the Tech2(R) for the current time and date. REMINDER - Keep in mind that the time displayed on the Tech2(R) is in Greenwich Mean Time(GMT) and the offset is based on the time zones relationship to GMT.

If replacement of the VIU/VCIM is necessary, you MUST reconfigure the OnStar system. Failure to reconfigure the system will result in an additionalcustomer visit for repair. OnStar VIU, Generations 2 and 3, will require the technician to press the blue OnStar button to reconfigure the vehicle withan OnStar advisor.

OnStar(R) VCIM, Generations 4-7 will require the technician to reconfigure the vehicle with the use of the TIS2WEB and SPS applications (pass thruonly), along with the Tech2(R).

The configuration and set-up procedure is a two-step process that must be completed step-by-step without interruption or delay in between each step.This procedure enables an automated activation without a button press by the technician to the OnStar(R) Call Center. Following this procedure, it maytake up to 24 hours for all OnStar(R) services to be fully activated.
How to Order Parts

If the OnStar(R) GPS date/time stamp is non-recoverable and the unit needs to be replaced, dealers in the U.S. should contact Autocraft Electronicsselect the catalog item that contains this bulletin number. Canadian dealers should contact MASS Electronics.

Dealers DO NOT need to call the GM Technical Assistance Center (TAC) for replacement approval. Autocraft Electronics and MASS Electronics willbe responsible for verifying that the subject vehicle is a candidate for a replacement VIU/VCIM.

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.

This bulletin is being revised to add models and model years. Please discard Corporate Bulletin Number 00-08-46-004B (Section 08 - Body andAccessories).

When servicing any of the above models and a battery cable is disconnected or power to the OnStar(R) Vehicle Communication Interface Module(VCIM) is interrupted for any reason the following procedure must be performed to verify proper Global Positioning System (GPS) function.

Never swap OnStar(R) Vehicle Communication Interface Modules (VCIM) from other vehicles. Transfer of OnStar(R) modules from other vehiclesshould not be done. Each OnStar(R) module has a unique identification number. The VCIM has a specific Station Identification (STID). Thisidentification number is used by the National Cellular Telephone Network and OnStar(R) systems and is stored in General Motors Vehicle History filesby VIN.
After completing ALL repairs to the vehicle you must perform the following procedure:

Move the vehicle into an open area of the service lot.
Sit in the vehicle with the engine running and the radio turned on for five minutes.
Press the OnStar(R) button in the vehicle.
When the OnStar(R) advisor answers ask the advisor to verify the current location of the vehicle.

If the vehicle location is different than the location the OnStar(R) advisor gives contact GM Technical Assistance (TAC) and choose the OnStar(R)prompt. GM OnStar(R) TAC will assist in the diagnosis of a failed VCIM and, if appropriate, order a replacement part. Replacement parts are usuallyshipped out within 24 hours, and a pre-paid return package label will be included for returning the faulty part. By returning the faulty part, you will avoida non-return core charge.
