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

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 .
