Pinpoint Test Ag: The Abs Module Does Not Respond To The Diagnostic Scan Tool

WARNING: This page is about a different car, the 2021 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
  1. Normal Operation and Fault Conditions 

    With the ignition ON, the diagnostic scan tool communicates with the ABS module over the HS-CAN2. Communications can be interrupted by a wiring condition such as a short to ground, a short to voltage or an open circuit; module failure may also be a cause of no communication.

    Refer to Communications Network to diagnose the no communication concern. REFER to: COMMUNICATIONS NETWORK .

    • Fuse
    • Wiring, terminals or connectors
    • EBB unit (electric boosted vehicles)
    • ABS module (vacuum boosted vehicles)
