Instrument panel problem.

[The Freeman]

I have a Berlingo 2001 16V petrol. After a bsi reset I have a blinking key symbol on the panel and my speed-, rpm, temp, fuel and clock metering doesn't work.

I did a lexia reading and it says:

• Permanent error no communication from BSI to VAN
• Permanent error no communicatie with instrument panel
• Permanent error communication via the DATA-kanaal from the comfort-network
• Permanent error communication via the DATAB-kanaal from the comfort-network
• BSI dialogue yes, error yes
• Instrumenten panel dialogue no, error ---
• Injection dialogue yes, error no
• Airbag dialogue yes, error no

I can fire the motor on and drive with it but have a blinking key symbol on the panel and my speed-, rpm, temp, fuel and clock metering doesn't work.

I appreciate some help.

Can you write exact BSI reset procedure you followed.

Thanks for your question.

I did the bsi reset because my front wipers didn't work in the interval and low speed setting.

BSI procedure

1. Open the bonnet
2. Open the driver's window
3. Switch all equipment off
4. Close the door and remove the key
5. Wait 3 minutes
6. Disconnect the positive pole from the battery and wait 15 seconds
7. Connect the positive pole to the battery and wait 10 seconds
8. Without opening the door switch the side lights on
9. Open the door and switch on the ignition
10. Check system's functionality

My key with the remote is broken. So I didn't hold the lock button on key down for 10 seconds.

Check for water ingress to BSI.
Your BSI is not communicating with the rest of the car electronic.
Also check can lines on BSI. Those wires are "twisted" , you can spot them easy.

BSI reset procedure can't render this fault "Permanent error no communication from BSI to VAN"
unless something is really bad with your BSI

Thanks.

I removed the car radio and found some loose wires and I reconnected them. Also I removed the instrument panel to see if the connectors are good attached. And the were.

I loosen the BSI but not totally. I couldn't see any water ingress and the connectors are on the bottom side of the BSI. So water can't come in to the connectors. To totally remove the BSI and Fuse box, I think that is a major and difficult job. Because the hole dashboard needs to be removed.

I'am not sure if this is the right thing to do?

A few year ago I had the same problem after I ignited the car in the winter with a poor battery. And after driving the car for several weeks with a blinking key symbol on the panel and no speed-, rpm, temp, fuel and clock metering working. Suddenly it worked again.

Is my BSI reset procedure correct?
And can I do it without the key with the remote? I use the spare key for years.
Any other suggestions?

Kind Regards,
The Freeman.

If you don't see any water ingress and from your description : "Suddenly it worked again"
seems like "loose wire" but again I can't be 100% sure if BSI or something else is the problem.


Instrument panel is receiving information over can lines from BSI. If no communication from
BSI to instrument panel you have: "Permanent error no communication from BSI to VAN"
and dials are "dead"

Permanent error communication via the DATA-kanaal from the comfort-network
Permanent error communication via the DATAB-kanaal from the comfort-network

The above errors indicates that both of the Can lines are "disconnected".
If your clock and fuel level works then your instrument panel is receiving +12 volts.
It is not receiving CAN messages. Fuel sensor is connected directly to dial on instrument panel.
Either BSI is not sending CAN messages or Instrument panel is not receiving them!

Thank you again.

Yes, I understand that it is difficult too be 100% sure what the cause is.

How can I detect CAN lines which are going to the instrument panel?
Can I measure if CAN communication from BSI is delivered to instrument panel?
If so how?
Is the 12 Volts to the instrument panel coming from the BSI?
Is my BSI reset procedure correct?
And can I do it without the key with the remote? I used the spare key for the BSI reset.

Kind Regards,
The Freeman

Can lines are easy to find out. On connector find 2 wires that are "twisted"
Connector going to instrument cluster or connector going to BSI.
To measure CAN communication you need logic analizer or oscillosope.
In your case it is enough to measure voltage and resistance.
Here is the guide: http://www.esd-electronics-usa.com/CAN-B...Guide.html
+12 volts to instrumet panel is going over fuse. Don't know number. Find in manual.
Your BSI procedure is correct, you don't need remote key.

And I must correct my self: 
"Either BSI is not sending CAN messages or Instrument panel is not receiving them!"

In your case it is not possible that BSI is not sending CAN messages because there will be different error if BSI is not sending/receiving.
any CAN massages. In your case It seems that only instrument panel is not receiving/sending CAN messages to BSI.

Thank you Brajomobil.

I took the two connectors loose from the instrument panel and measured to find the 12 Volt when contact is turned on. I found on the left connector no 12 Volts. All pins were 0 Volts. On the right connector I found on two pins 12 Volt.

Do I need 12 Volt on the left connector of the instrument panel?

Unfortunately I couldn't measure voltage and the resistance of the CAN communication at the instrument panel. Because I see no twisted wires and I can't see to which pin the wires go to, because of the construction of the connector.

I took the BSI out of the car and opened it. It was all clean and I couldn't see anything wrong. So I guess the BSI is okay!

Is there a way to test the BSI now its out of the car?

The only thing I can see to do to solve the problem I have, is looking for broken wires or bad contact.

[brajomobil]

Twisted wires are all the way. You can't miss them. Check pic.

Lights on instrument panel are working ?
Then +12 is going to instrumet panel, wright ?


To test BSI on the table is little tricky. 
You can do it but it is not 100%.
