	Removing
	Notes on using tester for tire pressure monitoring systems	Tester MB 2000E	AH40.15-P-0001-01A
1	Remove valve cap (1)	Only use valve caps (1) made of plastic otherwise corrosion damage will occur
2	Detach tires	Model 210, 211, 215, Model 220 without code Z07 Top protection and PAX system emergency wheel, Model 230, Model 240 without CSR system emergency wheel	AR40.10-P-1030A
3	Unscrew union nut (2) and remove spacer ring (2a) from valve body (3)	If necessary insert assembly tool for tire pressure monitor or pin (2 mm dia.) for counterholding in bore (3b).
4	Remove TPM wheel sensor (A69/1 to A69/5) with valve body (3)
5	Unscrew bolt (3a) and remove valve body (3) from TPM wheel sensor (A69/1 to A69/5)	When reusing the TPM wheel sensor (A69/1 to A69/5) If necessary insert assembly tool for tire pressure monitor or pin (2 mm dia.) for counterholding in bore (3b).
	Clean
6	Clean TPM wheel sensor (A69/1 to A69/5)	When reusing the TPM wheel sensor (A69/1 to A69/5) Do not remove white filter surface on the underside of the TPM wheel sensor (A69/1 to A69/5). Only remove dirt with a clean, lint-free cloth. Do not use compressed air, solvents or cleaners.
7	Clean the disk wheel in the area of the valve bore
	Checking
8	Carry out visual inspection of the TPM wheel sensor (A69/1 to A69/5)	When reusing the TPM wheel sensor (A69/1 to A69/5) Replace the TPM wheel sensor (A69/1 to A69/5) if the white filter surface is damaged or dirty. TIREFIT tire sealant has been used. Damage is recognizable. It is more than 5 years old according to the date of manufacture (H).
9	Check disk wheel for damage in the area of the valve bore
	Install
10	Detach the label (4) with the identification number (i) of the TPM wheel sensor (A69/1 to A69/5) and affix to the maintenance booklet	When replacing the TPM wheel sensor (A69/1 to A69/5) The identification number (i) is also noted on the TPM wheel sensor (A69/1 to A69/5). Observe transmission frequency (F) of the TPM wheel sensor (A69/1 to A69/5): Vehicles with code 494 USA version: 315 MHz Vehicles without USA version: 433 Mhz
11	Replace bolt (3a), valve body (3) and union nut (2) with spacer ring (2a)	When reusing the TPM wheel sensor (A69/1 to A69/5) Guide bolt (3a) into TPM wheel sensor (A69/1 to A69/5) and screw on valve body (3) approx. 3 revolutions
12	Insert TPM wheel sensor (A69/1 to A69/5) with valve body (3) into the valve bore of the disk wheel	The bore (3b) must point upwards.
13	Mount spacer ring (2a) and tighten union nut (2)	Observe the tightening torques for the different gasket versions: ↓
		Gasket of valve body modified. If necessary insert assembly tool for tire pressure monitor or pin (2 mm dia.) for counterholding in bore (3b).	BT40.15-P-0080-01A
			*BA40.15-P-1001-01A
14	Tighten screw (3a).	In the process press the TPM wheel sensor (A69/1 to A69/5) slightly into the drop center of the disk wheel.
			*BA40.15-P-1002-01A
15	Mount tire	Model 210, 211, 215, Model 220 without code Z07 Top protection and PAX system emergency wheel, Model 230, Model 240 without CSR system emergency wheel	AR40.10-P-1030A
	To activate the tire pressure monitor, carry out operation step 16 or  17 as an alternative
16	Code the identification number (i) of the TPM wheel sensor (A69/1 to A69/5) and specified tire pressure in the TPM control unit using STAR DIAGNOSIS	When replacing the TPM wheel sensor (A69/1 to A69/5) Process all steps under: Control units - Chassis - TPM tire pressure monitor - Initial startup - initial startup with manual adjustment of the new control unit.
17	Activate the tire pressure monitoring system	When replacing the TPM wheel sensor (A69/1 to A69/5) On model 211, 219.3, 230, 240: ↓ Perform adjustments to the control system
