Is the resistance greater than 10,000 ohms?

Yes	GO to A6
No	REPAIR the circuit in question. After the repair: If no Diagnostic Trouble Codes (DTCs) are present, TEST the system for normal operation. If DTC U1000:00 is present, CLEAR the Diagnostic Trouble Codes (DTCs) and REPEAT the self-test (required to enable the lamp output driver if DTC U1000:00 is present). If DTC U3000:49 is present, Click here to access Guided Routine (BCM).
