Hello!
It has been some time since I last wrote a message in this nice forum. This time is about the ECUs on my
1999 Espace V6 24V
I bought an
AUTEL Maxidiag JP701 reader to get some info from another of my cars, a
2000 Mitsubishi Carisma 1.8 GDI. Well, success with it was not great, as I only got the 'no error codes stored' message, while I know there are some!
So today I have checked the unit with my brother's
2008 Honda Jazz. Wow, what a difference!. I could even get real time measurements. My next (used as always) car will be OBD-II compliant, for sure
!!!
Then I have decided to try luck with the
Espace. Yesterday night I had read several messages on this forum abut it and was not really too confident. But as I saw that the Espace had a
CAN bus controller (it says so in the electronics box besides the fuses), I wanted to give it a try.
First thing I had to do was to hack my JP701 reader, which is intended for Japanese cars (the one needed was the FR704) to add Renault cars as well. I found the info and it is just a matter of adding, by USB, another file to the unit. Pretty neat and easy
!!!
So I have connected the reader to the OBD connector and have tried first autoscan with
OBD-II/EOBD modes, which in turns check all kind of interfaces, from KWP-2000 to several CAN systems, to ISOs and so on. But no luck, as expected.
Then I have entered the Renault menu for
non-OBD-II cars and have found that there was an
Espace model selectable and also two
Espace IV models (one of them
Phase II). So I have selected
Espace and then
Petrol engine... and, yes, it has connected to the car bus
So I have tested then
Engine ECU and have got three errors, one current and two stored. And they make some sense, I think, as two of them relate to O2 sensor loop while the other is a configuration error (which could be due to a battery disconnect some time ago). Then I have tried
ABS ECU and it has also connected, giving no errors. And then I have checked
AIRBAG ECU and have got some open circuit errors in a couple front lateral sensors, which could be just real. The only ECU which has refused to talk is the
AT ECU (transmission). For the three ECUs I have got also some info (model codes and such)
All in all, I have had no guts (yet
) to clear errors, just in case I fried something
. But it seems that the communication and decoding is done nicely. What do you think?
Best regards,
JOSE
