Removal Procedure

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 GMC Yukon XL, 2003 GMC Yukon, 2003 Chevrolet Tahoe, 2003 Chevrolet Suburban, and 2003 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Before servicing any electrical component, the ignition key must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.

Important:  After installation, calibrate the new EBCM to the tire size that is appropriate to the vehicle.

  1. Disconnect the negative battery cable.
  2. Raise and suitably support the vehicle.

    Important:  The area around the EHCU MUST be free from loose dirt to prevent contamination of disassembled ABS components.

  3. Thoroughly wash all contaminants from around the EHCU (1).
