Inadvertent Power Courtesy Lamps Circuit Test

WARNING: This page is about a different car, the 2008 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the X3 harness connector at the BCM.
  2. 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. If the circuit tests normal and the B+ circuit fuse is open, test the inadvertent power courtesy lamp circuit for a short to ground.
  3. Ignition OFF, connect the harness connector at the BCM.
  4. Disconnect the harness connector at the inoperative lamp.
  5. Test for less than 5.0 ohms of resistance between the appropriate ground circuit terminal listed below and ground.
    • Dome lamp - terminal B
    • Courtesy/map lamp - terminal D
      • If greater than the specified range, test the ground circuit for an open/high resistance.
  6. Ignition ON, verify that a test lamp illuminates between the inadvertent power courtesy lamp circuit terminal and ground.
    • Dome lamp - terminal C
    • Courtesy/map lamp - terminal A
      • If the test lamp does not illuminate, test the inadvertent power courtesy lamp circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the BCM.
  7. If all circuits test normal, replace the inoperative lamp.
