Berlingo 2,0 HDI 2004 electric fault

[stefansmark]

Hi there.

I am new to this forum, I got my first Berlingo yesterday even though I promised myself never to own one....

I am experiencing some electrical errors in my car.
The previous owner said that he was fixing something with the steering column when the car went crazy on him.

When the key is turned on the display starts to blink STOP and all the warning lights come on.
The odometer display shows the oil level for a while then it starts showing multiple horizontally aligned lines.
The engine will crank but it doesn't start.

No electrical features work inside the. I get no reaction whatsoever on turning lights, wipers, warning blink, radio, ac button, electric assisted windows, nothing.

I tried to reset the BSI according to the instructions i found here, the problem is i can't lower the window so i had to sit in the car while a friend of mine disconnected and reconnected the battery.

I changed the battery in the key remote to make sure there is no error there, however i don't know if it actually works since there is no reaction when i push the buttons.

All the fuses check out OK and i can't find any obvious errors.
Tomorrow i will try to get the fault codes read, any suggestions on what to do until then?

When electrics go silly always check earths first. Especially check any connections to earth from the steering column

I tried checking if there was any loose cables after the previous owner was fixing with the steering but i cant see anything there

Next time you want to do a bsi reset just barrel the door catch over so it thinks the door is shut

As for your issue, I'd plug it into planet or lexia and see what you can and can't read, this uses canbus which is what I suspect you have an issue with to one part or another!

Hi, 

What year is your Berlingo?
Do you know what the previous owner was 'fixing' when things went crazy? 
Any feedback on the fault code reading?

My berlingo is year 2004.

Today i checked with a simpler kind of obd reader, it doesnt communicate with the car even though there is power in the obd outlet.
I tried to measure the can bus cables but i cant seem to understand it.

With the battery connected and the ignition turned on, i tried to measure between the red/white can bus cables in the front fuse box and minus on the battery. No voltage in either of the cables.

With the battery out of the car i tried to measure the resistance between the two can bus cables in the front, without undoing any of the cables and measuring on the backside of the connector i get a reading of about 2 kohm.

I dont get any smarter, where i should i continue to look?

Is the computer fried?

Your car will almost certainly be VANBUS rather than CANBUS, but I'm not sure what difference that will make at the electrical level on the wiring. Does your simple OBD reader communicate OK with your Bluetooth device? If so, you probably need to try Lexia or Diagbox. The VANBUS OBD connector will communicate on a few different pins to Lexia depending on what ECU it's talking to, so a simple OBD reader may well not tell you the whole picture.
