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.
NOTE:

When removing connectors, inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector:

  • Seat position sensor
  • SDM module
  • Seat position sensor wiring harness connector
  • SDM wiring harness connector
  1. Ignition OFF, disconnect the harness connector at the appropriate B88 seat position sensor.
  2. Test for less than 10 Ω between the low reference circuit terminal 1 and ground.
    • If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K36 SDM.
  3. Ignition ON, test for 4-9 V between the signal circuit terminal 2 and ground.
    • If less than the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K36 SDM.
    • If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the K36 SDM.
  4. If all circuits test normal, replace the B88 seat position sensor.
