INSTALLATION





1. Position ABS control assembly into bracket and tighten nuts.
Torque:
ABS Control Assembly-to-Bracket Nuts: 20 Nm (15 ft. lbs.)





2. Position brake pipes into master cylinder and tighten brake pipe nuts.
Torque:
Brake Pipes-to-Master Cylinder: 18 Nm (13 ft. lbs.)





3. Position brake pipes into ABS control assembly and tighten brake pipe nuts.
Torque:
Brake Pipes-to-Master Cylinder: 18 Nm (13 ft. lbs.)

IMPORTANT: Ensure that all electrical connections are fully seated and latches are engaged.

IMPORTANT: If EBTCM was replaced, make sure to program the correct engine and transaxle options in the EBTCM. (Refer to option bit configuration with Scan tools.)





4. Install electrical connector to ABS control assembly.
5. Install negative battery cable.
6. Fill brake fluid reservoir with clean brake fluid up to "MAX" mark on reservoir.
