1. Vehicle OFF, disconnect the X2 harness connector at the K9 Body Control Module.
2. Verify that a test lamp illuminates between the B + circuit terminal 3 X2 and ground.
If the test lamp is not illuminated, it should be noted.
3. Connect the harness connector to the K9 Body Control Module and disconnect the harness connector.
4. Test for less than 5 Ω between the tail light and the ground light.
• E4J Sidelight - Left Front harness connector terminal 1
• E5AA Tail / Brake Lamp - Left harness connector terminal 3
