VIDA/DICE unit needed for diagnostics

I have also noticed hearing two donks from somewhere below the dash on the driver's side low down close to the firewall, just before the motor cuts.

The donks sound like a vacuum system device or valve shutting. This is petrol but I know diesel motors have a magnetic valve that shuts off the fuel supply. Does anyone know if a petrol motor has the same?

Can you check the fuel pump to make sure its not that ?

If you put it on ACC 2 does the pump run ?

OR you could short out Ter 15 to 87 to power up fuel pump and try again.

Dont leave it like this for long as it will run the fuel pump continuously with ignition on. ;-)

The donk you hear maybe the ETM closing at shutdown.

Thanks for advice.
I have checked that fuel is pumping to the injector fuel rail by disconnecting the fuel pipe before the rail and cranking motor. The fuel pumps out normally while motor is cranking (without it being able to fire coz fuel pipe is disconnected) The problem starts after it fires. Within seconds of firing it dies
like something is causing the fuel to be cut at the injectors (poss the ECU - I believe it can do this under certain circumstances) or it could be the fuel pump cutting off through something that happens AFTER it fires, because with the fuel pipe disconnected, the fuel can be seen to be pumping up to the connection into the injector fuel rail.

It is definitely fuel being cut for some reason that kills the motor, as I have checked that the plugs are firing ok and have seen that they continue firing right up to (and even slightly after) when the motor dies.

The fault has the characteristics of what happens when something goes wrong within the key chip/antenna ring/immobilizer unit signalling to the ECU which causes the ECU to cut the motor after firing. But having tried replacement antenna rings and another of the cars ignition keys without success, in this case I doubt it is that type of fault.

What exactly is the ETM ? Would you advise testing fuel pressure with a fuel pressure tester? What are Ter 15 to 87 and where are they located?

Hi, have you seen this ETM flow Chart from Xemodex https://xemodex.com/us/pdf/ETM%20Flo...ew%20final.pdf
I appreciate you may fail at the first question but then again it may give an answer.

Cheers Peter

Thanks for chart. When it's daylight I'll take it out to the vehicle and follow the trouble shooting on it to see if anything can identify a fault.

Have followed troubleshooting chart and found that the ETM doesn't click on and whine as the chart says it should. The troubleshooting then says to circuit test the ECM plug which the chart clearly shows to have 6 pins. The problem is my ECM plug only has 3 pins. This suggests my ECM is different to the charts. Would anyone know which of the pins on my 3 pin plug are the equivalent of pins 5 and 6 on the charts plug?

The later occurrences in my previous post of ECM is an error. I meant ETM (electronic throttle module) sorry.

Hi CSCUK

Does your 1999 V70 have an ignition coil, distributor cap and spark plug wires?

Or does it have an electronic throttle module, and 5 ignition pencils (one for each cylinder)?

The ETM looks like this

How many keys do you have for this car? If the chip in a key is faulty or is not valid for the car, the car will run just for a few seconds then stop (the security system turns it off). Can you try a different key? Do you have a valet/glove box key? I cannot remember if they will fit the ignition lock barrel or not, think not. Has the ignition lock been changed, or have you done anything relating to the keys?

Does the alarm siren work? If the alarm goes off, and you put a valid key in the ignition and turn it on, the siren should turn off.

Hope some of that helps,
Steve
