IMAGER Shim Adjustment

NOTE: The following procedure is used to mechanically adjust the SmartBeam® imager (camera) ONLY after the SmartBeam® Calibration Procedure has resulted in a High Beam Camera Alignment Performance Fault - Left, Right, Top or Bottom Diagnostic Trouble Code (DTC) or a combination of any two of these faults being set. The imager is assembled to a mounting bracket on the inside rear view mirror with four screws. Four stepped plastic shims along with an integral plastic tree that joins the shims are factory assembled between the mounting bracket and the imager at the time of manufacture. A single shim is located at each screw location. The following procedure details the proper steps for repositioning the appropriate shims to correct each fault or combination of faults. However, retrieval and erasure of the DTC to complete and verify the procedure will require the use of a diagnostic scan tool and the appropriate diagnostic information.

NOTE: The SmartBeam® Module is also known as the Automatic High Beam Module (AHBM) in the diagnostic information and Scan Tool.

Using a diagnostic scan tool, read and record the SmartBeam® (also known as the Automatic High Beam Module/AHBM) Diagnostic Trouble Code (DTC) data. Refer to SMARTBEAM® .
Adjust the inside rear view mirror head (3) downward far enough to access and remove the two screws (2) that secure the rear cover (1) to the imager housing.
Adjust the mirror head up toward the headliner to its uppermost position.
Unsnap and pull the upper edge of the rear cover away from the imager housing far enough to disengage the tabs at the lower edge of the cover, then remove the cover from the housing.

Refer to IMAGER ADJUSTMENT TABLE for the fault code or codes that have been recorded. Carefully cut the plastic tree for the shims (2) at the appropriate location or locations (boxed numbers in the preceding graphic) for the fault or fault combination.

Refer to IMAGER ADJUSTMENT TABLE for the fault code or codes that have been recorded. Locate and loosen one-half turn (counterclockwise) those screws on the rear view mirror bracket (1) at the appropriate locations (circled letters in the preceding graphic) for the fault or fault combination.

B16A7 - Left	(1)	(B) and (C)

If more than one High Beam Camera Alignment Performance Fault DTC was retrieved, the appropriate screws should be loosened and their shims relocated for both of the two faults. One screw and one shim will be common to both of the faults. In this case, the total amount of available correction will be slightly diminished from that available for a single fault. However, in most cases, this action should result in a sufficient amount of correction to remedy both fault conditions.

Slide the shim beneath each of the loosened screws to its most outboard position.
Tighten each of the loosened screws to secure the imager and shims to the mirror bracket. Tighten the screws to 0.8 N.m (7 in. lbs.).
Engage the tabs at the lower edge of the rear cover to the bottom of the imager housing. Be certain that the imager wiring is held against the mirror bracket, then snap the upper edge of the cover into place on the housing.
Install and tighten the two screws that secure the rear cover to the imager housing. Tighten the screws to 0.7 N.m (6 in. lbs.).
Use the diagnostic scan tool to erase any SmartBeam® DTC data. Refer to SMARTBEAM® .
The SmartBeam® calibration procedure should be performed following any imager shim adjustment procedure. See Electrical - Lamps and Lighting/Lamps/Lighting - Exterior/SMART BEAM - Standard Procedure .
