Diagnosis And Testing - Exterior Lighting: SMARTBEAM®

NOTE:

For SmartBeam® to operate, the Auto High Beam option must be enabled using the customer programmable features function of the Electronic Vehicle Information Center (EVIC). Also, the BCM must be properly configured for the automatic headlamps option using a diagnostic scan tool. Refer to the appropriate diagnostic information.

CONDITION	POSSIBLE CAUSES	CORRECTION
SMARTBEAM® INEFFECTIVE AND RED LED ON INSIDE REAR VIEW MIRROR NOT ON	1. Feature not enabled.	1. Enable Auto Dim High Beams using the customer programmable features function of the Electronic Vehicle Information Center (EVIC).
	2. Automatic headlamps are not turned ON.	2. Turn automatic headlamps ON using the control knob of the headlamp switch.
	3. Headlamp high beams are not selected.	3. Turn high beam headlamps ON using the beam selector function of the multi-function switch control stalk.
	4. Vehicle speed is below 34 kilometers-per-hour (18 miles-per-hour).	4. Increase vehicle speed. SmartBeam® is not designed to operate at speeds below 34 kilometers-per-hour (18 miles-per-hour).
	5. Ineffective ElectroChromic (EC) mirror inputs or outputs.	5. Use a diagnostic scan tool and the appropriate diagnostic information for further EC mirror diagnosis.
	6. Incorrect Body Control Module (BCM) configuration.	6. Use a diagnostic scan tool to check and correct the BCM configuration settings if required. Refer to the appropriate diagnostic information.
	7. SmartBeam® imager lens dirty or obstructed.	7. Clean imager lens and windshield or remove obstructions from the windshield glass if required.
	8. Ineffective ground circuit.	8. Test and repair open ground circuit to inside rear view mirror as required.
	9. Ineffective feed circuit.	9. Test and repair open fused run relay output circuit to inside rear view mirror if required.
	10. Loss of CAN data bus or LIN data bus communication.	10. Use a diagnostic scan tool and the appropriate diagnostic information for further CAN data bus or LIN data bus diagnosis.
	11. Internal faults in imager camera or EC mirror circuitry.	11. Use a diagnostic scan tool and the appropriate diagnostic information for further imager camera and EC mirror (AHBM) diagnosis.
SMARTBEAM® INEFFECTIVE AND RED LED ON INSIDE REAR VIEW MIRROR FLASHING CONTINUALLY	1. SmartBeam® calibration required (slow flash - once-per-second).	1. Perform the SmartBeam® Calibration procedure.
SMARTBEAM® INEFFECTIVE AND RED LED ON INSIDE REAR VIEW MIRROR ON CONTINUOUSLY	1. SmartBeam® failed calibration procedure due to improper set up.	1. Perform the SmartBeam® Calibration procedure properly.
	2. SmartBeam® failed calibration procedure due to a mechanical misalignment.	2. Use a diagnostic scan tool to retrieve the Diagnostic Trouble Code (DTC). Refer to the appropriate diagnostic information.
