Installation Procedure

Notice: To prevent equipment damage, never connect or disconnect the wiring harness connection from the EBCM with the ignition switch in the ON position.

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  1. Install the brake pressure sensor to the EBCM in the vehicle.
  2. Tighten
    Tighten the pressure sensor to 22 N·m (16 lb ft).

  3. Connect the brake pressure sensor electrical connector.
  4. Position the EBCM back into the support bracket and tighten the retaining nuts.
  5. Tighten
    Tighten the retaining nuts to 10 N·m (89 lb in).
