Circuit/System Testing

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2010 GMC Yukon XL, 2010 GMC Yukon, 2010 Chevrolet Tahoe, 2010 Chevrolet Suburban, and 2010 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector of the yaw rate sensor.
  2. Ignition ON, verify that a test lamp illuminates between the module voltage circuit and ground.
    • If the test lamp does not illuminate, test the circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM.
  3. Ignition OFF, test for less than 5 ohms between the module ground circuits and ground.
    • If greater than the specified value, test the ground circuit for an open/high resistance. If the circuit tests normal, replace the EBCM.
  4. If all circuits test normal, replace the yaw rate sensor.
