What is the procedure for scanning. - Office Equipment & Supplies

Programming Theft Deterrent System Components
Important: When replacing a body control module (BCM) with an GM Service Parts Operation (SPO) Replacement Part, set up the replacement BCM prior to the 10-minute relearn procedure or the 30-minute relearn procedure. Refer to Body Control Module (BCM) Programming/RPO Configuration in Body Control System.
Important:
• When replacing a BCM with an GM SPO Replacement Part, the module will learn the keys immediately. The existing powertrain control module (PCM) must learn the new fuel continue password when you replace the BCM.
• When replacing a PCM with a GM SPO Replacement Part, the new PCM will learn the incoming fuel enable password immediately after programming and upon receipt of a password message. A PCM which had been installed in another vehicle would have learned the fuel enable password of the other vehicle's BCM. Perform either the 10-minute relearn procedure or the 30-minute relearn procedure to learn the fuel enable password of the current vehicle's BCM.
• When performing either relearn procedure, all previously learned keys will be erased from the BCM memory.
• Additional keys may be learned. Refer to Adding Keys .

• Engine replacement

If the standard bleeding procedures do not produce an acceptable pedal you will need a scantool that can activate the automated ABS bleed and a pressure bleeding system.
To bleed the brakes use the standard pattern of RR,LR,RF,LF

ABS Automated Bleed Procedure
Caution: Refer to Brake Fluid Irritant Caution in Service Precautions.
Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in Service Precautions.
Important: In most circumstances a base brake bleed is all that is required for most component replacements (such as wheel cylinders, calipers, brake tubes, and master cylinder) except for brake pressure modulator valve (BPMV) replacement.
The following automated ABS bleed procedure is required when one of the following occur:
Manual bleeding at the wheel cylinders does not achieve the desired pedal height or feel.
BPMV replacement
Extreme loss of brake fluid has occurred.
Air ingestion is suspected.
If none of the above conditions apply, use standard bleed procedures.
The auto bleed procedure is used on BOSH 5.3 equipped vehicles. This procedure uses a scan tool to cycle the system solenoid valves and run the pump in order to purge the air from the secondary circuits. These secondary circuits are normally closed off, and are only opened during system initialization at vehicle start up and during ABS operation. The automated bleed procedure opens these secondary circuits and allows any air trapped inside the BPMV to flow out toward the wheel cylinders or calipers where it can be purged out of the system.
Automated Bleed Procedure
Preliminary Inspection
Inspect the battery for full charge, repair the battery and charging system, as necessary.
Connect a scan tool to the data link connector (DLC) and select current and history DTCs. Repair any DTCs prior to performing the ABS bleed procedure.
Inspect for visual damage and leaks and repair, as needed.
Preliminary Setup
Raise and vehicle on a suitable support.
Turn the ignition switch to the OFF position.
Remove all 4 tires, if necessary.
Connect the pressure bleeding tool according to the manufacturer's instructions.
Turn the ignition switch to RUN position, engine off.
Connect a scan tool and establish communications with the ABS system.
Pressurize the bleeding tool to 206 - 241 kPa (30 - 35 psi) .
Performing the Automated Bleed Procedure
Notice: The Auto Bleed Procedure may be terminated at any time during the process by pressing the EXIT button. No further Scan Tool prompts pertaining to the Auto Bleed procedure will be given. After exiting the bleed procedure, relieve bleed pressure and disconnect bleed equipment per manufacturers instructions. Failure to properly relieve pressure may result in spilled brake fluid causing damage to components and painted surfaces.
With the pressure bleeding tool at 206 - 241 kPa (30 - 35 psi) , and all bleeder screws in closed position, select Automated Bleed Procedure on the scan tool and follow the instructions.
The first part of the automated bleed procedure will cycle the pump and front release valves for one minute. After the cycling has stopped the scan tool will enter a cool down mode and display a 3 minute timer. The auto bleed will not continue until this timer expired, and cannot be overridden.
During the next step, the scan tool will request the technician to open one of the bleeder screws. The scan tool will then cycle the respective release valve and pump motor for one minute.
The scan tool will repeat step 3 for the remaining bleeder screws.
With the bleeder tool still attached to the vehicle and maintaining 241 kPa (35 psi) , the scan tool will instruct the technician to independently open each bleeder screw for approximately 20 seconds. This should allow any remaining air to be purged from the brake lines.
When the automated bleed procedure is completed the scan tool will display the appropriate message.
Install all 4 tires, if necessary refer to Tire and Wheel Removal and Installation.
Remove pressure from the pressure bleeding tool and then disconnect the tool from the vehicle.
Depress the brake pedal to gage pedal height and feel. Repeat steps 1-8 until the pedal is acceptable.
Remove the scan tool from the DLC connector.
Install.
Lower the vehicle.
Inspect the brake fluid level in master cylinder.
Road test the vehicle while making sure the brake pedal remains high and firm.
If the vehicle is equipped with a traction control system (TCS), the scan tool will cycle both the ABS and the TCS solenoid valves. This bleed procedure is the same as above.
