Circuit/System Testing

2006 Chevrolet Suburban K2500, 6.0 USECTION 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.

Right Side Object Sensor Malfunction

  1. Ignition OFF, disconnect the harness connector at the right side object sensor.
  2. Test for less than 5 Ξ© between the ground circuit terminals listed below and ground:
    • Terminal 5
    • Terminal 6
    • If greater than the specified range, test the appropriate ground circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  4. If all circuits test normal, replace the right side object sensor.

Left Side Object Sensor Malfunction

  1. Ignition OFF, disconnect the harness connector at the left side object sensor.
  2. Test for less than 5 Ξ© between the ground circuit terminal 5 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  4. Ignition OFF, disconnect the harness connector at the right side object sensor.
  5. Ignition ON, test for less than 1 V between the serial data circuit terminal 4 and ground.
    • If greater than the specified range, test the serial data circuit for a short to voltage.
  6. Test for infinite resistance between the serial data circuit terminal 4 and ground.
    • If not the specified value, test the serial data circuit for a short to ground.
  7. Test for less than 2 Ξ© between the serial data circuit terminal 4 at the left side object sensor harness connector and the serial data circuit terminal 4 at the right side object sensor harness connector.
    • If greater than the specified range, test the serial data circuit for an open/high resistance.
  8. If all circuits test normal, replace the left side object sensor.

Side Object Indicator Malfunction

  1. Ignition OFF, disconnect the X3 and X7 harness connectors at the appropriate door lock/window switch.
  2. Apply ground to the low reference circuit X3 terminal 8.
    • If the blind zone indicator in the outside rearview mirror illuminates, test the control circuit X7 terminal 8 for short to voltage.
  3. Apply battery voltage to X7 terminal 8 and ground to X3 terminal 8.
    • If the blind zone indicator in the outside rearview mirror does not illuminate, test the control circuit X7 terminal 8 and reference circuit X3 terminal 8 for short to ground or an open/high resistance.
  4. If all circuits test normal, test or replace the appropriate outside rearview mirror.
  5. Verify blind zone indicator functions, if not test or replace the appropriate door lock/window switch.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • β€’ You smell fuel, burning insulation, or see smoke.
  • β€’ Brakes feel soft, pull hard to one side, or make grinding noises.
  • β€’ The engine overheats, stalls repeatedly, or misfires under load.
  • β€’ You are missing required tools, torque specs, or safe lifting equipment.
  • β€’ You are not confident in the next step or safety outcome.
