Volvo vadis

[delambo]

Did you ever get Vadis to work realist? I have downloaded a copy of it but every time I go to use it, it says vadis data not completely installed please check installation or reinstall! I dont know if I need the data seperate from the install disk. This is rather urgent as I have promised a customer their car back by end of play tomorrow. If you cant help me here then perhaps you could tell me what code P1081 and P1083 are on a volvo V70, S reg, drive by wire.

[jakeyfly]

did you ever find any infor on these codes mate?. im looking at a 1999 volvo v70 2.5 20valve petrol with a denso engine managment system, engine code B5254S. no comms with acr4 map, snappy dont do it, kts dont do it and volvo fcr dont do it, the only comms i could get was with obd2 digimoto giving 4 dtc's
P1032
P1053
P1059
P1081
very little serial data but what was there was ok apart from a lazy lamda voltage, to be honest i dont trust the data, bit flaky.
P1053 wont clear and P1081 comes back under cranking.
not getting car back for a couple of days but struggling to find any info on these codes, did you have any luck??
cheers

P1032/ECM-91A7 = Throttle unit internal fault (faulty signal)
P1053/ECM-91F0 = Throttle unit internal fault (faulty signal)
P1059/ECM-532D = MIL requested by the throttle unit (faulty signal)
P1081/ECM-720A = Immobiliser communication (faulty VIN code / faulty communication / no communication)

P1059

The throttle unit has requested that the warning lamp is lit.


Substitute value
None.


Possible source

Diagnostic trouble code (DTC) ECM-532D is stored in the engine control module (ECM).


Fault symptom[s]
None.

P1081

The engine control module (ECM) interprets the following as faults: If the engine control module (ECM) does not communicate with the immobilizer control module within 2 seconds of the ignition being switched on, or the engine is started when the ignition has been on for too long without the ignition being turned off in between. “No communication”. If the +15 supply between the ignition and the engine control module (ECM) is switched on and off while driving, “faulty signal”. If a faulty VIN CODE is sent from the immobilizer control module. Diagnostic trouble code ECM-720A is stored.


Substitute value
None.


Possible source

Faulty communication:
-the ignition has been switched on and off more than three times while driving.
No communication:
-immobilizer control module in the diagnostic mode
-faulty key (transponder read off or not programmed)
-open-circuit in the signal cable between the immobilizer control module and the engine control module (ECM)
-defective immobilizer control module
-defective immobilizer control module.
Incorrect VIN code:
-defective immobilizer control module
-defective immobilizer control module
-defective engine control module (ECM)
-faulty engine control module (ECM).


Fault symptom[s]
-the engine starts but stops immediately.


P1032

Diagnostic trouble code (DTC) ECM-91A7 is stored if the engine control module (ECM) registers an internal or external fault.


Substitute value
-the accelerator pedal (AP) is ignored when braking
-the cruise control cannot be activated
-the engine speed (RPM) is limited using fuel shut off. The maximum permitted engine speed depends on the accelerator pedal (AP) position
-throttle unit in mechanical limp home mode, the throttle disc in fixed position (only 5 cylinder engines with DENSO electronics).


Possible source

-something is blocking the throttle position sensor (an oil film, dust etc.)
-poorly charged battery or corroded in the connecting cables
-the power supply to the throttle unit
-old software in the throttle unit
-defective throttle unit.


Fault symptom[s]
-the accelerator pedal (AP) is ignored when braking
-the cruise control cannot be activated
-uneven idle
-jerks during engine braking
-very poor throttle response (only 5 cylinder engines with DENSO electronics)
-maximum speed approximately 50 km/h (only 5 cylinder engines with DENSO electronics)
-the ETS warning lamp lights (C70 and S/V70 -2000 only).

Checking the electronic throttle module (ETM) and software
Check battery and charging system. This diagnostic trouble code (DTC) may be stored before the battery voltage becomes too low.
Check the electronic throttle module (ETM) connector. Check for contact resistance and oxidation.
Thoroughly check the throttle for dirt and sticking. Check that no objects are blocking the throttle. Check for dirt and sticking visually by pressing the throttle disc to change the angle.
Hint: Small objects can cause the throttle disc to jam momentarily, this can cause the diagnostic trouble code (DTC).
Read off the software number in the electronic throttle module (ETM) by clicking the VCT2000 symbol. Always check that the software number corresponds to the latest VOLVO software. See the service information for information about the latest software.
Hint: The diagnostic trouble code (DTC) may be the result of a faulty electronic throttle module (ETM). If the diagnostic trouble code (DTC) persists, despite the above checks and remedies, try a new electronic throttle module (ETM).
Caution! A new electronic throttle module (ETM) is delivered without software. For the electronic throttle module (ETM) to function after replacement, it must be programmed.

P1053

Check that the connector terminals for the electronic throttle module are OK. Check that there is voltage to the throttle unit from the system relay. With ignition on there should be a cheeping noise from the throttle unit for a moment, when it receives voltage.
Check that the battery voltage is normal. Check that the charging status of the battery is OK.
Symptom check
In certain cases to determine if the fault is permanent or intermittent the engine must be started and stopped up to three times (to force the fault to occur). Cancel when the symptoms appear in the car but keep the engine running.
Hint: Check for symptoms between each start of the engine. See the fault code information. The symptom “accelerator pedal (AP) is ignored when braking” can be used as a check. In the event of faults, it is not possible to increase the engine speed (RPM) at the same time as the brake pedal is depressed.
Note! The supply voltage to the electronic throttle module must be interrupted to empty the memory between each start.
Hint: Interrupt the supply voltage to the electronic throttle module by removing the affected fuse. Do not forget to insert the fuse before the next engine start. See the fuses In the integrated relay / fusebox in the engine compartment.
Read off diagnostic trouble codes (DTCs) with the engine running.

thats the info i was hoping for mate, thanks. just been reading about all the problems with the magneti marelly throtle bodys, seems it a common problem, not one that i have come across till now, so its out with the scope again. have you any pin data on this? and may i ask where you got info from
cheers

[delambo]

I got Vadis working. If you want to pm me your address I'll burn you off a copy. When I couldnt get to the bottom of the problem I told my customer that I would have another look when I see it again. The only pin data that I have is what is in Autodata.

[Realist]

Naaa, have the disc but no hardware to connect it to my car.

Laters

[delambo]

Posted it today Jakefly. Is a bit of a pain to setup, but if you follow te setup instructions it will work for 10 years.

[delambo]

Did you ever get it to work jakefly?

[jakeyfly]

No not yet, but i havent tryed since the last time i mailed you, not enough time in the day, but will have ago soon and let you know
cheers

[Realist]

Purchased a lead and software and still bugger all works.

Owe well, sell the car and get one to match the cable LOL
