Circuit/System Testing

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2011 GMC Yukon XL, 2011 GMC Yukon, 2011 Chevrolet Tahoe, 2011 Chevrolet Suburban, and 2011 Chevrolet Avalanche. 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 harness connector at the multifunction switch assembly-I/P. It may take up to 2 minutes for all vehicle systems to power down.
  2. Test for less than 5 Ω between the ground circuit terminal 3 and ground.
    • If 5 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 circuit.
      • If less than 2 Ω, repair the open/high resistance in the ground connection.
    • If less than 5 Ω 
  3. Ignition ON.
  4. Verify the scan tool Traction Control Switch parameter is Inactive.
    • If not Inactive 
    1. Ignition OFF, disconnect the X2 harness connector at the BCM.
    2. Test for infinite resistance between the signal circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance, replace the BCM.
    • If Inactive 
  5. Install a 3 A fused jumper wire between the signal circuit terminal 1 and the ground circuit terminal 3.
  6. Verify the scan tool Traction Control Switch parameter is Active.
    • If not Active 
    1. Ignition OFF, disconnect the X2 harness connector at the BCM, ignition ON.
    2. Test for less than 1 V between the signal circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V
    3. Test for less than 2 Ω in the signal end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the BCM.
    • If Active 
  7. Test or replace the multifunction switch assembly-I/P.
