Circuit/System Testing

WARNING: This page is about a different car, the 2017 GMC Acadia Limited, 2017 Chevrolet Traverse, and 2017 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:

Diagnose any antilock brake system (ABS) related DTCs before performing this diagnostic.

  1. Ignition OFF, disconnect the X4 harness connector at the radio.
  2. Ignition ON, operate the vehicle drive wheels at 5 mph. Test for 3 - 7 Hertz between the VSS circuit terminal 5 and ground.
    • If not within the specified range, test the VSS circuit for an open, high resistance, short to ground or short to voltage. If the circuit tests normal replace the EBCM.
  3. If the circuit tests normal, replace the radio.
