Alarm Module: Description and Operation
SYSTEM OPERATION (BUICK)

The PASS-Key II Theft Deterrent system prevents vehicle theft by disabling the starter motor and fuel system. If the Body Control Module (BCM)does not identify the use of the correct ignition key to start the vehicle, the BCM will communicate a message to the Powertrain Control Module(PCM) which will disable the starter relay and fuel delivery to the engine.

When the BCM identifies the use of the correct ignition key (resistor pellet) to start the vehicle, the BCM will then send a "fuel enable" and "starterenable" message to the PCM which will allow the vehicle to start.

Important

If the wrong ignition key is used in an attempt to start the vehicle, a Data Trouble Code (DTC) will be set and the Body Control Module (BCM) willnot send a "fuel enable" or "starter enable" message to the Powertrain Control Module (PCM) for three minutes even if the correct ignition key isused.

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.

SUBJECT:Correction of Various Front End Noises

MODELS:1997-99 Buick Century/Regal1998-99 Oldsmobile Intrigue1997-99 Pontiac Grand Prix

This bulletin is intended to provide information to help identify and correct various front end noises in 1997-1999 Buick, Pontiac, and Oldsmobilemidsize vehicles. Though many components are shared between these vehicles, specific noise related customer concerns may be present in only a selectgroup of vehicles. This bulletin provides specific information regarding the make and model affected with any known cut off points (VIN # or Date). It isnot intended to contain all possible sources of front end noise, but will identify some of the harder to diagnose items.
The subjects of this bulletin include the following:

- WHINE/WHISTLE or TONE at 32 km/h (20 mph) with slight steering input (Magnasteer (R) only).

- A CLUNK that can be produced when the vehicle's engine is running, but not when it is off.

- A CLUNK that can be produced, both when the engine is running and when it is off.

- A CLUNK/RATTLE/POP heard during low speed maneuvers or while driving down the road.

- A CHIRPING or SQUEAKING sound from the front suspension when hitting sharp bumps.

- SNAPS, POPS and CREAKS from the front struts.

- A VIBRATION or ROUGHNESS in the steering.

CORRECTION

The following sections give information on the source and correction of various noises that may be found in midsize vehicles. Please see the applicableService Manual for the repair procedure in each case.

Electronic Brake Control Module: Customer InterestWhine/Whistle/Tone at 32 km/h (20 mph) w/Slight Steering Input

WHINE/WHISTLE, OR TONE AT 32 KM/H (20 MPH) WITH SLIGHT STEERING INPUT (MAGNASTEER (R) ONLY) - (1998 BUICK REGALGS, 1998 OLDSMOBILE INTRIGUE)

A whine or whistle may be heard in the passenger compartment of the vehicle. The tone may resemble a test tone and is most noticeable at 32 km/h (20mph) with slight steering inputs. The noise originates in the Magnasteer (R) Variable Assist Steering Gear.

Important:

For the Buick Regal, this condition applies only to a two month production of the GS model. During that time, the Oldsmobile Intrigueintermediate shaft was substituted for the Buick part. Check the concerned vehicle for a multi-splined intermediate shaft in place of the standardDOUBLE-D style shaft. Replace the splined shaft as instructed under "A Clunk that can be produced, both when the engine is running and when it is off"in this bulletin. Replace the shaft regardless of it's date code.

-

To diagnose this condition, disconnect the Magnasteer (R) Variable Assist (MSVA) harness (at the MSVA pigtail) from the steering gear and testdrive the vehicle again. If the noise has disappeared, then the MSVA system is the source.

-

To correct this condition, replace the Electronic Brake and Traction Control Module with a revised module (P/N 9353511). Refer to the LaborTime Guide for applicable operation number and time allowance.

Electronic Brake Control Module: Customer InterestA Clunk Produced When the Engine Is Running, NOT When It's Off

A CLUNK THAT CAN BE PRODUCED WHEN THE VEHICLE'S ENGINE IS RUNNING BUT NOT WHEN IT'S OFF (1998 BUICK REGAL GS,1998 OLDSMOBILE INTRIGUE)

This type of noise is likely to be a steering gear condition; specifically too much clearance between the seal on the power piston and the groove that theseal rides in. This excessive clearance lets the piston seal knock inside the groove during turns.

-

With the vehicle stationary and the engine running, turn the steering wheel rapidly back and forth over it's center position. Complete a cycle ofboth directions about once a second. The wheel must be turned this quickly in order to bring about the noise. Next, repeat this rapid turning overcenter with the engine off.

-

If the clunk was present with the engine on, but not when turned off, the rack may be the source. Verify the date of vehicle manufacture. Thiscondition was corrected in production by February 1,1998. If the vehicle is older then this date and has not had a steering rack replacement,replace the rack. If the vehicle is newer than February 1,1998 refer to the applicable Service Manual and follow the normal diagnostic proceduresbefore changing the rack.

Electronic Brake Control Module: Customer InterestA Clunk Produced When the Engine Is Running and When It's Off

A CLUNK THAT CAN BE PRODUCED BOTH WHEN THE ENGINE IS RUNNING AND WHEN IT'S OFF (1998 BUICK REGAL, 1998OLDSMOBILE INTRIGUE)

Important:

The above condition applies only to a two month production run of the 1998 Buick Regal. During this period, the splined intermediateshafts were installed in place of the standard DOUBLE-D style shaft. These vehicles were all equipped with the early version of the splined shaft whichis prone to the clunk noise. If a Buick Regal with this condition is encountered, replace the shaft with the DOUBLE-D style that is designated in the GMParts Manual as original equipment.

This type of clunk is likely to be caused by the intermediate shaft. This clunk may be caused by too much clearance between the splined inner and outerparts of the slider joint. The additional clearance allows them to knock against each other during turns.

- The correction is to replace the intermediate shaft with one built since the middle of October, 1998.

-

Check the shaft's date code to assure that it is a good shaft. The code can be recognized by the fact that it's laser-etched, rather than stamped on theend of the shaft. The shaft must have been built on or later than the 280th day of 1998 (example: "252A8"). In this example, the "282" representsthe 282nd day and the final "8" represents 1998.

Electronic Brake Control Module: Customer InterestA Clunk/Rattle/Pop Heard While Driving or Low Speed Maneuvers

A CLUNK/RATTLE/POP HEARD DURING LOW SPEED MANEUVERS OR WHILE DRIVING DOWN THE ROAD (1998 OLDSMOBILEINTRIGUE)

This noise in it's various forms is likely to be caused by either under-torqued bolts in the front strut mounts or by an older intermediate shaft. Thefollowing is how to distinguish between the two possible causes:

- Begin diagnosis by verifying the torque of the front strut mounting bolts which may have been under-torqued during assembly.

TIGHTENTighten the front strut mounting bolts to 33 Nm (24 lb ft).

-

If the clunk"rattle remains once the mounting bolts are correctly torqued, the cause may be a second condition with the intermediate shaft. Beforeit can be heard, this condition can be felt as a sharp knocking or tapping feel in the steering wheel. Eventually it will become an audible rattle ortapping. This noise is most obvious at low speed. The rattle or tapping is heard when driving over a series of small bumps, but may change to aclunk or pop with light brake application or acceleration.

- This condition may be caused by an insufficient distribution of lubricant between the mating splines of the slider shaft.

-

The correction is to replace the intermediate shaft with one built since the middle of October, 1998. Check the shaft's date code to assure it is agood shaft. The code can be recognized by the fact that it is laser-etched, rather than stamped on the end of the shaft. The shaft must have beenbuilt on or later than the 280th day of 1995 (example: "282A8"). In this example, the "282" represents the 282nd day and the final "8" represents1998.

Important:

Do not remove the intermediate shaft to examine or perform any operation that will "stroke" the shaft. This movement of the slider joint,past normal in-car positioning, will redistribute the grease on the shaft and temporarily eliminate the condition. The only way to permanently repair thevehicle is to replace the shaft if it is identified as one of the early shafts prone to this condition.

Electronic Brake Control Module: Customer InterestA Chirping/Squeaking Sound From Front Suspension Hitting Bumps

A CHIRPING OR SQUEAKING SOUND FROM THE FRONT SUSPENSION WHEN HITTING SHARP BUMPS (1998 OLDSMOBILEINTRIGUE, 1999 PONTIAC GRAND PRIX)
A chirping or squeaking sound may be heard from the front suspension when hitting a sharp bump such as a deep pothole or a speed bump.

-

This condition may be caused by an internal misbuild of the strut. The base valve and deflection disc may allow improper fluid flow (internal tothe strut). The unwanted flow between these two components creates the chirping noise.

- This condition was corrected on all Oldsmobile Intrigues beginning with VIN # XF341675 or vehicles built after January 1, 1999.

- This condition was corrected on the Pontiac Grand Prix after VIN # XF265000.

-

The only correction for this noise is replacement of the strut. Struts can be checked by locating the Julian Date stamped into the strut housingapproximately 1/3rd of the way up from the bottom of the strut and facing inward when installed. Beginning with the third digit, any date afterXX8355 (8=1998 355=day) can be considered good.

Electronic Brake Control Module: Customer InterestSnaps, Pops, and Creaks From the Front Struts

SNAPS, POPS, AND CREAKS FROM THE FRONT STRUTS (OLDSMOBILE INTRIGUE, PONTIAC GRAND PRIX)
Snaps or pops from the front struts during low speed turns and braking may be the result of two possible conditions:

-

If the Intrigue in question was built in 1997, the cause of this condition may be due to a strut. Refer to Service Bulletin Number 73-33-O4 foradditional information.

-

The other possible cause is that the jounce bumper inside the top of the dust boot is rubbing on the bump plate or cap. To correct this condition,raise the vehicle and with the wheel hanging, raise each front dust boot. Rub wheel bearing grease or other heavy grease onto the bump plate. If theplate comes off the strut housing when the dust boot is lifted, press it back into place firmly before greasing. This repair is so quick, this optionmay be explored whenever there is a concern about steering or front end noise.

Electronic Brake Control Module: Customer InterestA Vibration or Roughness In the Steering

A VIBRATION OR ROUGHNESS IN THE STEERING (BUICK CENTURY/REGAL, OLDSMOBILE INTRIGUE AND PONTIAC GRAND PRIX)

This is a feeling of roughness or lumpiness in the steering. This is a subtle condition that may not be obvious like steering shudder. This condition istypically felt during lane changes at highway speed on smooth pavement. It is never felt when the steering wheel is turned and the vehicle is stationary.

-

This condition is called "tire flutter" because it originates with the tires. it tends to worsen with increased miles on the vehicle and tires. Theseverity of this condition will vary with different types of tires. Any time this type of concern is encountered, test drive the vehicle against anotherIntrigue.

-

If the condition is significantly greater in the customer's car, rotate the tires front to rear. This does not always correct the condition, but it is theonly known correction for this type of concern.

Electronic Brake Control Module: Customer InterestWhine/Whistle/Tone at 32 km/h (20 mph) w/Slight Steering Input

WHINE/WHISTLE, OR TONE AT 32 KM/H (20 MPH) WITH SLIGHT STEERING INPUT (MAGNASTEER (R) ONLY) - (1998 BUICK REGALGS, 1998 OLDSMOBILE INTRIGUE)

A whine or whistle may be heard in the passenger compartment of the vehicle. The tone may resemble a test tone and is most noticeable at 32 km/h (20mph) with slight steering inputs. The noise originates in the Magnasteer (R) Variable Assist Steering Gear.

Important:

For the Buick Regal, this condition applies only to a two month production of the GS model. During that time, the Oldsmobile Intrigueintermediate shaft was substituted for the Buick part. Check the concerned vehicle for a multi-splined intermediate shaft in place of the standardDOUBLE-D style shaft. Replace the splined shaft as instructed under "A Clunk that can be produced, both when the engine is running and when it is off"in this bulletin. Replace the shaft regardless of it's date code.

-

To diagnose this condition, disconnect the Magnasteer (R) Variable Assist (MSVA) harness (at the MSVA pigtail) from the steering gear and testdrive the vehicle again. If the noise has disappeared, then the MSVA system is the source.

-

To correct this condition, replace the Electronic Brake and Traction Control Module with a revised module (P/N 9353511). Refer to the LaborTime Guide for applicable operation number and time allowance.
