Retrofit Astra H TPMS

Salutare tuturor.

De curand am zarit un topic pe un site extern in care un tip a reusit sa isi monteze DDS si TPMS pe masina.

Am aflat ca pentru a activa sistemul si a fi perfect funcional ar fi necesare urmatoarele :

Pompa ABS compatibila cu Alpha Code : HC, HK, HD, AM, AK, AJ, AS, AT, BG, BM, BN, BP, BQ, BR
Unitate de Control TPMS
4 senzori de presiune - toti 4 acelasi Alpha Code
Buton in bord - cu 2 - 4 - sau 6 - da ... exista si cu 2 - DDS si Inchidere Usi.
Display GID / CID
IPC compatibil ( aici ma refer la faptul ca o sa trebuiasca adaugat un LED pentru TPMS ) - se poate rezolva la CristianTM
Programare Tech2 ( nu stiu daca merge cu OP-COM )

La toate astea mai adaugam cablaj - Problema intervine aici - TIS200-ul meu face figuri , nu vrea sa mai porneasca si nu pot scoate o schema electrica.

Ceva ajutor ?

Tech2 au sigur - dar pe mine ma intereseaza o schema electrica pentru a vedea cum se leaga unitatea de control la masina.

Daca ai motor de 1.7 nu te ajuta la nimic.

Daca are masina ESP - daca nu de design.

tmps ala este o porcarie, mai ales iarna cand rotile de iarna nu au prevazuti senzori in roti si sta pomul de craciun activat toata perioada rece

Sistemul este foarte bun si chiar indicat pentru cauciucurle de tip run-flat. Pe acest gen de anvelopa daca nu ai ochiul format e cam greu sa-ti dai seama ca ai pana

Din ce am mai citit pentru:

*DDS nu-ti trebuie decat butonul si unitatea ABS care sa stie functia + programare cu Tech-2 . Nu necesita cablaj suplimentar

*TPMS - senzori de roti(valve), GID sa CID, IPC compatibil, unitate radio + cablaj, programare


Have fun



Two different tyre pressure monitoring systems are used on the Astra-H.

DDS

The DDS is a function of the ABS MK60 ESP and calculates the pressure loss in the tyres via the wheel speed sensors of the ABS. When the vehicle is being driven, the speed of each wheel is monitored continually. Loss of pressure in the tyre reduces the tyre's diameter and thereby the rotational speed of the wheel. If the system detects a difference in rotational speed such as this, the control indicator (red) will light up. The DDS is an indirect measurement system as it only gives a warning about loss of air but does not say which tyre/wheel is affected.

The control indicator lights up when there is a pressure deviation of approx. 30% compared with the other tyres. If there is a fault in the system, the (yellow) control indicator lights up.

TPMS

The tyre pressure monitoring system (TPMS) is a direct measuring system which works together with the DDS. Four pressure and heat sensors located in the tyres continually monitor the inflation pressure whilst the vehicle is being driven. The air/inflation pressure is transmitted by radio wave directly to the TPMS control unit (which is also a receiver). In contrast to the Vectra-C, the TPMS on the Astra-H only works with one receiver (TPMS control unit). All signals received (pressure, heat) are first evaluated by the TPMS control unit and transmitted on the CAN bus via the ABS control unit to the instrument cluster.

The current tyre inflation pressures can be read from the Info Display.

If the system detects that there is a pressure difference in one or more tyres, an indicator appears in the Info Display showing the position of the faulty tyre. Pressure differences down to 0.1 bar can be displayed.

For the system to work, all wheels have to be fitted with pressure sensors, all tyres have to be inflated to the specified air pressure and the system has to be initialised.

The tyre pressure monitoring system is ready to operate once the ignition is on and continually checks the tyre pressure once the vehicle has reached a speed of 30 km/h.

Control unit for tyre pressure monitoring system



The DDS operates together with the TPMS and serves as a back-up system should one or all of the tyre pressure sensors fail. The DDS system indicates a deviation in air pressure or a system fault by means of a control indicator in the instrument panel:
◦Yellow display, system fault
◦Red display, deviation in tyre pressure

The spare wheel is not fitted with a tyre pressure sensor.

Should there be a deviation in tyre pressure, the TPMS displays the following messages in the Info Display along with the current measurements for the individual tyres:
◦Slight pressure deviation: Display reads "Check rear left tyre pressure"
◦Large pressure deviation: Display reads "Warning! Pressure loss in left rear tyre"

If there is a fault with one or all of the tyre pressure sensors, the TPMS operation automatically switches to the DDS system of the ABS. It calculates the pressures automatically from a speed of approx. 30 km/h by means of the wheel speed sensors.

Vehicles with tyre pressure monitoring systems can be recognised by the fact that the tyre valve stems are made of metal and have aluminium caps, instead of the usual rubber stems and plastic caps.

In the event of a puncture, do not use liquid tyre repair systems as they will damage the tyre pressure sensors.

The tyre pressure sensor contains a metal tyre valve. A non-changeable battery supplies the tyre pressure sensors with voltage.

DDS

After the tyre pressures have been corrected, or if a tyre or wheel has been changed or the wheels swapped over (e.g. a front wheel to the rear), the system must be reprogrammed/initialised:
◦Press the DDS button for 4 seconds (with the ignition on or engine running), the control indicator will flash 3 times
◦The system is operational once a certain distance has been covered, i.e. different speed ranges are programmed in by means of different driving profiles. It can take up to a maximum of one hour to program all the speed ranges.

TPMS/DDS

• Service:
After the tyre or wheel has been changed, the tyre pressure sensor replaced or the wheels swapped over (e.g. a front wheel to the rear), the system must be reprogrammed/initialised:
◦Press the DDS button for 4 seconds (with the ignition on or engine running), the control indicator will flash 3 times
◦The TPMS system will display the measured pressure in the Info Display after approx. 2 min (min. speed 30 km/h).
◦The DDS requires a certain distance to be covered for programming purposes (see above).
◦The DDS is used to allocate/position the pressure sensors / wheels.

The system at first only distinguishes between the front and rear axles (after 10 min. driving time at a min. of 30 km/h). Only when there is a loss of pressure does it distinguish between left and right as well.

If a customer is trying out the TPMS (e.g. by inflating the right tyre to a higher pressure), the display may indicate the wrong side of the vehicle (i.e. it may show that the left tyre has a higher pressure). Not until the vehicle is driving along will the previously programmed DDS then allocate the wheel or sensor correctly, after which the display in the Info Display will be correct.

Should the customer have concerns, assign the tyre pressure sensors unambiguously to the TPMS control unit by using the following programming procedure:

1

◦Reduce the tyre pressure to approx. 1 bar and re-inflate as described below.

◦Proceed with each tyre in turn.
◦Front left: 3.0 bar
◦Front right: 2.7 bar
◦Rear right: 2.4 bar
◦Rear left: 2.1 bar
◦Tyre pressure sensors are now active.



2
◦Drive the vehicle for a short while at a speed above 30 km/h to close the roll switches, i.e. activate the pressure sensors.
◦Inflate the tyres:
◦Front left: 3.0 bar
◦Front right: 2.7 bar
◦Rear right: 2.4 bar
◦Rear left: 2.1 bar

Then proceed as follows for both methods:
◦Press DDS button for 4 seconds (with ignition on or engine running).
◦Control indicator lights up yellow to confirm that the correct pressure setting has been detected (each pressure value must have been received once, total duration approx. 2 minutes).
◦Perform re-set again: Press DDS button for 4 seconds (with ignition on or vehicle running), control indicator will flash 3 times

The system has now assigned the pressure sensors unambiguously and is operational.

Both procedures should be carried out within 15 minutes.

The pressure can be read off from the Info Display (if the pressure should drop quickly, the transmission will occur while stationary).

On both versions, a faulty wheel sensor can be detected by the loss of the associated pressure value in the display.

Example: 2.7 bar is not displayed - front right wheel sensor is faulty.

Re-inflate the tyres to the correct pressure.

If a pressure sensor should fail during a journey, no pressures will be shown in the display.

To check the tyre pressures on vehicles with TPMS, attach the adapter, which is located on the tank filler flap, to the tyre valve before attaching the tyre pressure checker.

The seal rings of the valve stems and valve inserts must be replaced every time the tyre is changed. When tightening the nut on the tyre pressure sensor, it is essential to observe the specified tightening torque to prevent the sensor getting damaged. Information on fitting tyres can be found in the Astra-H Service Instruction, group "E".

TPMS control unit

The electronic control unit is the interface to the vehicle electrical and electronic systems. Wheel data is transmitted via RF (radio frequency) signals to the control unit where it is processed. The driver is informed of the current status via the Info Display. The control unit is connected to terminal 15 and terminal 31 as well as the low-speed CAN bus in order to communicate with other control units and for system diagnosis.
radio transmission: TPMS, 433 MHz connection between ECU and sensors
Warning and alarm

The system uses the standard tyre pressure as a reference, therefore the front and rear wheels may show different values.

If the tyre pressures have been increased by at least 0.1 bar, the control unit assumes the new values as the default values the next time the ignition is switched on.

A warning message is output:
◦Detected tyre pressures is -0.3 bar

An alarm message is output if:
◦Detected tyre pressure is -0.6 bar

Daca ai o diferenta de presiune mai mica de 0.3 bari roata isi micsoreaza diametrul si autmat calc. de ABS sesizeaza diferenta de roataie fata de celelalte roti si-ti aprinde ledul din buton in culoarea rosie.
Daca ai o setare defectuoasa sau sistemul nu functioneaza cum trebuie ledul de pe buton este portocaliu. In rest dupa ce este initializat nu se aprinde nimic.


Repet pentru DDS activ nu-ti trebuie led in IPC. Ledul din butonul din consola centrala face toata treaba. Verifica daca ai cablajul tras de la consola centrala la unitatea ABS. Daca esti norocos nu-ti ramane decat un simplu plug-n play pentru consola si butoane plus activare cu Tech-2(numai).

Referitor la schema electrica eu unul nu te pot ajuta, nu am TIS-ul.
DDS functioneaza bine merci fara TPMS. TPMS fara DDS nu se poate. In postul meu de mai sus ti-am dat un citat de pe un forum din UK unde este explicat foarte clar ca TPMS-ul nu face altceva decat sa reprezinte grafic starea presiunii in pneuri pe fiecare roata.

NU, un modul second care stie TPMS, DDS, HLA costa 500-600 euro pe cand unul care nu stie cred ca e vreo 100-200 euro.
Deeci m-as mira maxim sa puna din fabrica o piesa de mii de euro (atata cred ca face la Opel) in loc de sute de euro !

DDS tine de pompa de ABS. In primul post am scris cam 90% din alpha code-urile care suport DDS.

In dezmembrari am gasit pompa cu 350 LEI.
