	Remove/install
	Risk of injury  caused by fingers being pinched or crushed  when removing, installing or aligning hoods, doors, trunk lids, tailgates or sliding roof.	Keep body parts and limbs well clear of moving parts.	see AS00.00-Z-0011-01A
	Notes on avoiding damage to electronic components due to electrostatic discharge		see AH54.00-P-0001-01A
1	Remove right side paneling in trunk	Installation:  When replacing the trunk lid position sensor (B24/16), install right side paneling in trunk only after synchronizing sensor for new trunk lid position sensor (B24/16) and normalizing remote trunk closing.

2	Disconnect trunk lid position sensor connector (B24/16x1)	Installation:  When replacing trunk lid position sensor (B24/16) do not yet connect trunk lid position sensor connector (B24/16x1).
3	Expose electric wiring harness (4) on trunk lid position sensor (B24/16)
4	Press ball socket (8) off of hinge lever (7) and ball socket (2) off of rear fender
5	Remove hydraulic cylinder (1).
6	Unscrew bolt (6) and remove trunk lid position sensor (B24/16) together with electric wiring harness (4).	Installation:  Install trunk lid position sensor (B24/16) first on hydraulic cylinder (1) and then connect trunk lid position sensor connector (B24/16x1).
7	Install in the reverse order
8.1	Synchronize sensor to trunk lid position sensor (B24/16)	Only when replacing trunk lid position sensor (B24/16). To synchronize the sensor, first connect the wiring harness supplied to the trunk lid position sensor (B24/16) and then to the trunk lid position sensor connector (B24/16x1). Ensure that the trunk lid is manually opened and closed rapidly and without intermediate stop. If sensor synchronization is not successful, the operation can be repeated as frequently as required. Sensor synchronization: Move trunk lid by hand once up to upper stop, then close by hand and press into trunk lid lock. Open trunk lid, remove intermediate connector and directly reconnect trunk lid position sensor connector (B24/16x1). Erase error message "Sensor error" now present with STAR DIAGNOSIS.
	Connect STAR DIAGNOSIS and read out fault memory		see AD00.00-P-2000-04A
9.1	Denormalize remote trunk closing with STAR DIAGNOSIS and then normalize remote trunk closing	Only when replacing trunk lid position sensor (B24/16). Normalize remote trunk closing: Open trunk lid by actuating trunk lid handle; trunk lid opens automatically. Wait until TLC hydraulic pump switches off, then close trunk lid by actuating TLC button.
