WARNING: Refer to BRAKE FLUID IRRITANT CAUTION . CAUTION: Refer to BRAKE FLUID EFFECTS ON PAINT AND ELECTRICAL COMPONENTS NOTICE . CAUTION: Always connect or disconnect the wiring harness connector from the EBCM/EBTCM with the ignition switch in the OFF position. Failure to observe this precaution could result in damage to the EBCM/EBTCM. Preliminary Procedures Place the ignition switch in the OFF position. Clean the brake pipe fittings of any dirt or debris. Remove the underhood electrical center bracket. Refer to UNDERHOOD ELECTRICAL CENTER OR JUNCTION BLOCK BRACKET REPLACEMENT . Place a clean cloth under the brake modulator assembly to catch any brake fluid loss.

3	Front Brake Pipe Fitting (Qty: 2) Procedure Cap the brake pipe fittings to prevent brake fluid loss and contamination. Plug the brake modulator assembly outlet ports to prevent brake fluid loss and contamination. Tightening torque 21 N.m (16 lb ft)
4	Rear Brake Pipe Fitting (Qty: 2) Procedure Cap the brake pipe fittings to prevent brake fluid loss and contamination. Plug the brake modulator assembly outlet ports to prevent brake fluid loss and contamination. Tightening torque 21 N.m (16 lb ft)
5	EBCM to Brake Pressure Modulator Valve (BPMV) Screw (Qty: 4) Procedure Tighten the screws in a cross pattern. Tightening torque 3 N.m (27 lb in)
6	Electronic Brake Control Module (EBCM)
7	EBCM to BPMV Seal (Qty: 12)
8	Brake Modulator Assembly Bolt Tightening torque 20 N.m (15 lb ft)
9	Brake Pressure Modulator Valve Procedure Bleed the hydraulic brake system. Refer to HYDRAULIC BRAKE SYSTEM BLEEDING (PRESSURE) or HYDRAULIC BRAKE SYSTEM BLEEDING (MANUAL) . Turn the ignition switch to the ON position. DO NOT start the engine. Perform the DIAGNOSTIC SYSTEM CHECK - VEHICLE DIAGNOSTIC INFORMATION . Observe the feel of the brake pedal after performing the diagnostic system check. If the pedal now feels spongy, air may have been in the secondary circuit of the brake modulator assembly, which may have been introduced into the primary circuit. If the pedal feels spongy, perform the ANTILOCK BRAKE SYSTEM AUTOMATED BLEED PROCEDURE .
