proper box-end wrench onto the RIGHT FRONT wheel hydraulic circuit bleeder valve
20. Install a transparent hose over the end of the bleeder valve, then repeat steps 13-14.

25. Slowly depress and release the brake pedal. Observe the feel of the brake pedal.
Note: If it is determined that air was induced into the system upstream of the ABS modulator prior to servicing, the Antilock Brake System
Automated Bleed (See: ) must be performed.
26. If the brake pedal feels spongy, perform the following steps:
1. Inspect the brake system for external leaks. Refer to Brake System External Leak Inspection (See: Brakes and Traction Control/Hydraulic
System/Testing and Inspection/Component Tests and General Diagnostics/Brake System External Leak Inspection).
2. Using a scan tool, perform the antilock brake system automated bleeding procedure to remove any air that may have been trapped in the brake
pressure modulator valve (BPMV). Refer to Antilock Brake System Automated Bleed (See: ).
27. Turn the ignition key ON, with the engine OFF. Check to see if the brake system warning lamp remains illuminated.
Note: DO NOT allow the vehicle to be driven until it is diagnosed and repaired.
28. If the brake system warning lamp remains illuminated, refer to Diagnostic Starting Point - Vehicle (See: Testing and Inspection/Initial Inspection
