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.

Electronic Brake Control Module: Description and Operation
DESCRIPTION

The ABS system is controlled by a microprocessor based Electronic Brake Control Module (EBCM). Inputs to the system include four wheelspeed sensors, brakes, ignition switch and unswitched battery voltage. Outputs include three bi-directional motor controls, three lamp controls, twosolenoid controls and the system enable relay. A serial data line, located in terminal 9 of the Data Link Connector (DLC), is provided for servicediagnostic tools and assembly plant testing.

The EBCM monitors the speed of each wheel. If any wheel begins to approach lock-up and the brake switch is on, the EBCM controls the motorsand solenoids to reduce brake pressure to the wheel approaching lock-up. Once the wheel regains traction, brake pressure is increased until wheelbegins to approach lock-up. This cycle repeats until either vehicle comes to a stop, the brake is released or no wheels approach lock-up.Additionally, the EBCM monitors itself, each input and each output for proper operation. If any system fault is detected, the EBCM will store aDTC in nonvolatile memory.

On a EBTCM, the ABS portion of the module operates the same as a EBCM. A EBTCM is used if the vehicle is equipped with either theEnhanced Traction System (ETS) or Traction Control System (TCS). The ETS or TCS portion of the EBTCM monitors wheel spin slip throughthe drive wheels speed sensors. If the wheels begin to slip, the EBTCM determines the desired wheel torque needed to minimize wheel slip. Thisinformation is sent to the PCM through the Serial data link. On models equipped w/ETS, the PCM controls engine torque by ignition retard andtransmission shifts. On models equipped w/TCS, the PCM controls engine torque by ignition retard, transmission shifts and applies brakes severaltimes until the vehicle regains traction. Once the vehicle regains traction, brake pressure is decreased and engine torque reduction is no longerrequested. This cycle repeats until traction control is no longer necessary.

Models: 1996 Buick Century1996 Oldsmobile Ciera with 3100 V6 Engine (VIN M - RPO L82)

This bulletin is being revised to correct labor op under warranty information. Please discard Corporate Bulletin Number 67-65-31 (Section 6E - EngineFuel and Emission).
Condition

Some owners may comment that the engine idle will fluctuate on the initial cold start of the day prior to the vehicle being shifted out of Park position.This typically occurs at the point the emission control system goes from "open" loop to "closed loop" status. This condition is most noticeable in warmerambient temperatures.
Cause

The idle surge is caused by the difference in fueling between "open" and "closed" loop operation.
Correction
A new flash prom has been released to correct this condition. The following changes have been incorporated in the new flash prom:

1. Time delay increase to closed loop.

2. Smaller fueling corrections in the transition from open to closed loop.
These changes serve to take smaller fueling corrections from open to closed loop to avoid idle.
Parts Information
The new flash prom will be available from the GM Service Technology Group starting with CD # 16.

Important:

Do not attempt to order the flash proms from GMSPO. The flash proms are programmed into the PCM (Powertrain Control Module) via a TechlineTool device.
