Begin the hydraulic brake system diagnosis with the HYDRAULIC BRAKE SYSTEM DIAGNOSTIC CHECK under TROUBLE SHOOTING. The Diagnostic System Check will provide the following information:

The identification of the control module which command the system.
The ability of the control module to communicate through the serial data circuit.
The identification of any stored diagnostic trouble codes (DTCs) and their status.

The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.

Perform the BRAKE SYSTEM VEHICLE ROAD TEST under TROUBLE SHOOTING, before using the hydraulic brake symptom tables in order to duplicate the customer's concern.

Review the system operation in order to familiarize yourself with the system functions. See DESCRIPTION & OPERATION .
