Performing the Automated Bleed Procedure
2001 Chevrolet Cavalier LS, 2.4 TSECTION Performing the Automated Bleed Procedure
WARNING: This page is about a different car, the 2002 Pontiac Sunfire and 2002 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
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 J 29532 at 35 psi, and all the bleeder screws in the closed position, select the Automated Bleed Procedure on the scan tool and follow the instructions.
- The first part of the automated bleed procedure will cycle the pump and the front release valves for 1 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 expires. You cannot override this timer.
- The scan tool will request the technician to open one of the bleeder valves. The scan tool will then cycle this valve and the pump motor for 1 minute.
- The scan tool repeats step 3for the remaining bleeder valves.
- With the J 29532 still attached to the vehicle and maintaining 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 pipes.
- When the automated bleed procedure is completed, the scan tool will display the appropriate message.
- Remove pressure from the J 29532 and then disconnect the J 29532 from the vehicle.
- Depress the brake pedal in order to gauge the pedal height and feel.
- Repeat steps 1-8 until the pedal is acceptable.
- Remove the scan tool from the DLC.
- Lower the vehicle.
- Inspect the brake fluid level in the master cylinder.
- Road test the vehicle while verifying that the brake pedal remains high and firm.
