Circuit/System Testing

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 GMC Yukon XL, 2015 GMC Yukon, 2015 Chevrolet Tahoe, 2015 Chevrolet Suburban, and 2015 Cadillac Escalade ESV. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF and all vehicle systems OFF, disconnect the X3 harness connector at the appropriate A9 Outside Rearview Mirror. It may take up to 2 mins for all vehicle systems to power down.
  2. Test for less than 10 Ω between the ground circuit terminal 2 and ground.
    • If 2 Ω or greater 
    1. Ignition OFF.
    2. Test for less than 2 Ω in the ground circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the ground circuit.
      • If less than 2 Ω, repair the open/high resistance in the ground connection.
    • If less than 2 Ω 
  3. Ignition ON.
  4. Test for less than 1 V between the control circuit terminal 1 and ground.
    • If 1 V or greater 
    1. Ignition OFF, disconnect the harness connector at the B218R Side Object Sensor Module - Right..
    2. Test for less than 1 V between the control circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 2 Ω, replace the B218R Side Object Sensor Module - Right.
    • If less than 1 V 
  5. Command the Object Detection Alert Indicators On with a scan tool.
  6. Test for greater than 3 V between the control circuit terminal 1 and ground.
    • If 3 V or less 
    1. Ignition OFF, disconnect the harness connector at the B218R Side Object Sensor Module - Right.
    2. Test for infinite resistance between the control circuit and ground.
      • If less than infinite resistance, repair the short to ground in the circuit.
      • If infinite resistance
    3. Ignition OFF.
    4. Test for less than 2 Ω in the control circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the B218R Side Object Sensor Module - Right.
    • If greater than 3 V 
  7. Replace the appropriate E17 Outside Rearview Mirror Glass.
