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.

Models:

2011 and Prior GM Passenger Cars and Trucks

Attention:

This repair can be applied to ANY electrical connection including, but not limited to: lighting, body electrical, in-line connections, powertrain controlsensors, etc. DO NOT over apply lubricant to the point where it prevents the full engagement of sealed connectors. A light coating on the terminalsurfaces is sufficient to correct the condition.

Supercede:This bulletin is being revised to update the Attention statement and add the 2011 model year. Please discard Corporate Bulletin Number 09-06-03-004C(Section 06 - Engine/Propulsion System).

Condition

Some customers may comment on any of the following conditions:

- An intermittent no crank/no start

- Intermittent malfunction indicator lamp (MIL) illumination

- Intermittent service lamp illumination

- Intermittent service message(s) being displayed

The technician may determine that he is unable to duplicate the intermittent condition.

Cause

- Vibration

- Thermal cycling

- Poor connection/terminal retention

- Micro motion

- A connector, component or wiring harness not properly secured resulting in movement

Condition

Some owners may comment that the ABS light is on with Diagnostic Trouble Codes (DTC's) 46 and 86 set (rear ABS channel will not move) as currentor history. (DTC's 46 and 86 will be displayed as C1246 and C1286 on 1997 and 1998 model year vehicles).
Cause

A condition exists where the ABS motor pack gear (pinion) will bind on the motor armature shaft causing the motor not to move when commanded bythe EBCM. This condition is aggravated by light corrosion between the pinion and shaft. Therefore, it may occur more frequently when the weather ishot and humid.

Important:

Other EBCM and ABS motor pack concerns can also cause this condition, but they are not as common as the above cause.

Follow the included procedure (Attachments 1 and 2) for diagnosis. This condition may correct itself before the owner is able to bring the vehicle in forservice. Therefore, if DTC 46 is set in history, and is not currently setting, the included procedure will instruct you to replace the center ABS motorpinion. The new pinion has a Teflon insert which reduces friction between the pinion and motor armature shaft.
Pinion Replacement

If the included procedure instructs you to replace the center ABS motor pinion, use P/N 18029776. Please note that the new pinion is a directreplacement part which requires no modifications to the motor shaft. Follow the pinion replacement procedure included with the new pinion. Completemotor pack replacement is not required.

Some owners may comment that the ABS light is on with Diagnostic Trouble Codes (DTC's) 46 and 86 set (rear ABS channel will not move) as currentor history. (DTC's 46 and 86 will be displayed as C1246 and C1286 on 1997 and 1998 model year vehicles).
Cause

A condition exists where the ABS motor pack gear (pinion) will bind on the motor armature shaft causing the motor not to move when commanded bythe EBCM. This condition is aggravated by light corrosion between the pinion and shaft. Therefore, it may occur more frequently when the weather ishot and humid.

Important:

Other EBCM and ABS motor pack concerns can also cause this condition, but they are not as common as the above cause.

Follow the included procedure (Attachments 1 and 2) for diagnosis. This condition may correct itself before the owner is able to bring the vehicle in forservice. Therefore, if DTC 46 is set in history, and is not currently setting, the included procedure will instruct you to replace the center ABS motorpinion. The new pinion has a Teflon insert which reduces friction between the pinion and motor armature shaft.
Pinion Replacement

If the included procedure instructs you to replace the center ABS motor pinion, use P/N 18029776. Please note that the new pinion is a directreplacement part which requires no modifications to the motor shaft. Follow the pinion replacement procedure included with the new pinion. Completemotor pack replacement is not required.

Models:1988-96 Buick Regal1990-94 Chevrolet Lumina1988-97 Oldsmobile Cutlass Supreme1988-96 Pontiac Grand Prix

ConditionSome customers may comment on a grinding/scraping/groaning type noise coming from the rear suspension area that is audible in the passengercompartment. This condition typically occurs on high mileage vehicles that have been operated in areas exhibiting high levels of grit or sandcontamination. The noise is most apparent when the vehicle is operated over irregular road surfaces or during quick starting or braking maneuvers.

CauseThe wearing away or complete/partial detachment of the rubber tip pads on the rear transverse composite leaf spring may result in the unprotected springend sliding on the cast knuckle surface.

CorrectionReplace worn or missing rear spring rubber tip pads with those contained in spring tip service kit, P/N 10432057, using adhesive, P/N 10432060. Followthe applicable service procedure in the Rear Suspension sub-section of the Service Manual and those contained in the service kit.

: Notice

If the bare ends of the spring (tip pads removed) exhibit significant wear or gouging greater than 3 mm (1/8 in) in depth. then the spring is damagedbeyond repair and replacement is required.

Electronic Brake Control Module: Description and Operation
DESCRIPTION

(EBCM)

(DLC)

The controlling element of ABS VI is a microprocessor based Electronic Brake Control Module . Inputs to the system include four wheelspeed sensors, the brake switch, ignition switch, and unswitched battery voltage. Outputs include three bi-directional motor controls, four indicatorcontrols, two solenoid controls, and the system enable relay. A serial data line, located in terminal 9 of the Data Link Connector, isprovided for service diagnostic tools and assembly plant testing.

OPERATION

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 thewheel again begins to approach lock-up. This cycle repeats until either the vehicle comes to a stop, the brake is released, or no wheels approachlock-up. Additionally, the EBCM monitors itself, each input (except the serial data line) and each output for proper operation. If any systemmalfunction is detected, the EBCM will store a DTC in nonvolatile memory (DTCs will not disappear if the battery is disconnected). There is noserviceable or removable PROM. The EBCM must be replaced as an assembly.
