Alarm Module: Service and Repair

^Important

Any new PASS-KEY II(R) Theft Deterrent Module will automatically program to the resistance of the key (or Interrogator setting) being used atthe first ignition "ON" cycle. This can be done once for the life of the module.

New modules are unprogrammed. Before the system will function properly after a new module has been installed, it must be programmed to the codethat matches the customer's keys. Programming a new module is very simple.

1. Install the new, unprogrammed module.

2. Insert one of the customer's keys in the ignition lock cylinder and turn it to the "RUN" position. It's a good idea to start the engine at this time to
verify system operation.

3. Observe the indicator lamp:
^

The indicator lamp should light for about five seconds and then go out. If the wiring or contacts to the key resistance pellet or the key isdefective or intermittent and a new module is installed, the engine will start but the indicator will flash at a rate of one flash per second untilthe ignition switch is turned off. This indicates that the module did not program and that the system components, wiring and contacts should bechecked for a fault.

^Important

Before connecting the Interrogator to the ignition lock cylinder circuit, always verify vehicle key code and set the code into the Interrogator usingthe "key code" knob. This will prevent programming an unprogrammed module with an undesired key code.

Supercede:

This bulletin is being revised to update the models affected list above. Please discard Corporate Bulletin Number 06-08-46-007 (Section 08 - Body &Accessories).

Vehicles with this equipment will no longer be able to receive OnStar(R) services beginning January 1, 2008. At that time, service will be available onlythrough Dual-Mode (Analog / Digital) equipment. Analog-Only vehicles cannot be upgraded to digital equipment.

Disclaimer

All vehicles equipped with OnStar(R) listed in this bulletin were built with Analog-Only OnStar(R) Hardware. OnStar(R) equipped vehicles withanalog-only equipment were designed to operate only on the analog wireless network and cannot be upgraded for digital network compatibility.

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.

Intermittent No Crank/No Start, No Module Communication, MIL, Warning Lights, Vehicle Messages or DTCs Set by Various ControlModules - Diagnosing and Repairing Fretting Corrosion (Disconnect Affected Connector and Apply Dielectric Lubricant)

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

On low current signal circuits this condition may cause high resistance, resulting in intermittent connections.
On high current power circuits this condition may cause permanent increases in the resistance and may cause a device to become inoperative.

Electronic Brake Control Module: Description and Operation
DESCRIPTION

The EBCM is a small control computer located under the trim panel on the lefthand side of the passenger compartment on wagon models, and onthe lefthand side of the luggage compartment on sedan models. This computer monitors the speed of each wheel and the electrical status of thehydraulic modulator. The primary functions of EBCM are to detect wheel locking, control the brake function while in anti-lock mode and monitorsystem for correct electrical operation. The EBCM also controls the display of the ABS diagnostic trouble codes. If the EBCM detects a fault, itcan disable the ABS system and activate the ABS warning lamp.
