Notes on using tester for tire pressure monitoring systems - AH40.15-P-0001-01A
MODEL ALL
Use
The following testers (1) are available to read out the tire pressure sensors:
- Tester (1) for tire pressure sensors MB 2000E
- Tester (1) for tire pressure sensors MB 3000
Tire pressure sensors from the following system manufacturers can be read out:
- Continental (Siemens VDO)
- Huf (Beru)
- Schrader company
Tester (1) requirements
The tester (1) for tire pressure sensors MB 3000 must be update capable. When using the tester (1) for tire pressure sensors MB 3000 a check should be made to ensure that the latest software release is installed.
Observe the operator's manual for the tester (1) being used. An incorrectly used tester (1) may lead to faulty measurements.
Test prerequisites
Observe the following in order to prevent errors when reading out and evaluating the data:
- Maintain a distance (x) to other tire pressure sensors of at least 1.50 m.
- Position tester (1) exactly. The upper frontal area must be level with the valve (2) on the tire. Do not move from this position until the data is displayed.
- New tire pressure sensors cannot be read out because the tire pressure sensors do not send signals until a tire pressure above 3.2 bar has been applied.
- Tire pressure sensors from the system manufacturer Continental (Siemens VDO) must bear the "DC" identification, otherwise they will not be recognized (NON DC PART).
- Whether or not the battery status signal (BAT) is transmitted can only be checked reliably if the air temperature inside the tire is above +10 °C.
The remaining battery time can only be read out on the Huf (Beru) tire pressure sensor.
The Schrader WAL 1 tire pressure sensor cannot check the battery status.
If no or implausible data are output, repeat the measurement; move to a different location if necessary.
Lowering the tire pressure on the car by at least 0.3 bar accelerates the read-out procedure on the Huf (Beru) tire pressure sensor.
Do not replace tire pressure sensors based on data from the tester (1); an analysis using the diagnostic system must always be conducted here instead.
Otherwise, properly functioning tire pressure sensors may be replaced.
