REMOVING Removing     
IMPORTANT Notes on using tester for tire pressure monitoring systems Tester MB 2000E AH40.15-P-0001-01A
1 Remove valve cap (1) NOTES Only use valve caps (1) made of plastic otherwise corrosion damage will occur  
2 Detach tires   AR40.10-P-1030A 
3 Unscrew union nut (2) with friction disk (2a) from valve body (3) and remove    
4 Remove TPM wheel sensor (A69/1 to A69/4) with valve body (3)    
5 Unscrew valve body (3) from TPM wheel sensor (A69/1 to A69/4) When reusing the TPM wheel sensor (A69/1 to A69/4)
IMPORTANT If necessary insert assembly tool for tire pressure monitor or pin (2 mm dia.) for counterholding in bore (3b).		  
CLEAN Clean     
6 Clean the TPM wheel sensor (A69/1 to A69/4) When reusing the TPM wheel sensor (A69/1 to A69/4)
IMPORTANT Only remove dirt with a clean, lint-free cloth. Do not use compressed air, solvents or cleaners.
IMPORTANT The TPM wheel sensor (A69/1 to A69/4) can also be used again after the use of TIREFIT tire sealant.		  
7 Clean the disk wheel in the area of the valve bore    
INSPECT Checking     
8 Carry out visual inspection of the TPM wheel sensor (A69/1 to A69/4) IMPORTANT Replace the TPM wheel sensor (A69/1 to A69/4) if the
  • Damage is recognizable.
  • It is more than 7 years old according to the date of manufacture (H).

IMPORTANT The first two digits of the date of manufacture (H) specify the year of manufacture.		  
9 Check disk wheel for damage in the area of the valve bore    
INSTALLING Install     
10 Detach the label (4) with the identification number (i) of the TPM wheel sensor (A69/1 to A69/4) and affix to the maintenance booklet When replacing the TPM wheel sensor (A69/1 to A69/4)
IMPORTANT The identification number (i) is also noted on the TPM wheel sensor (A69/1 to A69/4).		  
11.1 Replace bolt (3a), valve body (3) and union nut (2) with friction disk (2a) When reusing the TPM wheel sensor (A69/1 to A69/4)
IMPORTANT Insert the square of the bolt (3a) in the guide on the TPM wheel sensor (A69/1 to A69/4) and screw on valve body (3) approx. 3 revolutions.		  
11.2 Fold valve body (3) downwards out of the horizontal position (arrow) When replacing the TPM wheel sensor (A69/1 to A69/4)
IMPORTANT Neither loosen or tighten valve body (3) of the new TPM wheel sensor (A69/1 to A69/4) for this
IMPORTANT Observe the transmission frequency (F) of the TPM wheel sensor (A69/1 to A69/4):
  • Vehicles with code 494 USA version: 315 MHz
  • Vehicles without USA version: 433 Mhz
  
12 Insert TPM wheel sensor (A69/1 to A69/4) with valve body (3) into the valve bore of the disk wheel    
13 Tighten union nut (2) with friction disk (2a) NOTES The union nut (2) must not  be reused. Under no circumstances counterhold the valve body (3) when tightening the union nut (2) otherwise the valve body (3) will not be screwed on correctly and the TPM wheel sensor (A69/1 to A69/4) will be damaged while driving.
IMPORTANT The effect of a breakage washer in the union nut (2) is that, when tightening, first the valve body (3) on the TPM wheel sensor (A69/1 to A69/4) is screwed on After perceptible fracture of the breakage washer the valve body (3) is then screwed on to the disk wheel.
IMPORTANT When tightening the union nut (2) press TPM wheel sensor (A69/1 to A69/4) slightly into the drop center and towards the valve bore of the disk wheel.		  
TORQUE SPECIFICATION *BA40.15-P-1001-01B 
14 Mount tire   AR40.10-P-1030A 
IMPORTANT To activate the tire pressure monitor, carry out operation step 15 or  16 as an alternative.    
15 Code the identification number (i) of the TPM wheel sensor (A69/1 to A69/4) and specified tire pressure in the TPM control unit using STAR DIAGNOSIS When replacing the TPM wheel sensor (A69/1 to A69/4)
IMPORTANT Process all steps under: Control units - Chassis - TPM tire pressure monitor - Initial startup - initial startup with manual adjustment of the new control unit.		  
16 Activate the tire pressure monitoring system When replacing the TPM wheel sensor (A69/1 to A69/4): ↓
