Technical '06 Panda crank sensor issue.....

[koalar]

Everything measured okay

You only needed to measure resistance between green cable and earth, battery disconnected

Green cable and power, battery disconnected

To finish the checks on this networks wiring

 

[RDM1]

I tried both the green and brown on power and ground and I'm getting OL

 

[koalar]

Great as far as wiring this network is fine

While the body computer is apart you might as well post some high resolution pictures and see if anything stands out

 

[RDM1]

And that's the resistance between green and brown on the car

 

[RDM1]

That's the 11 and 20 pins plug from the bottom and it doesn't add up that they go to 35 and 36 and just stop without any apparent connection from the other side or the same side.

 

[RDM1]

I'm not sure if you're good at electronics as I'm lost now anyway lets start with:

red giving perfect continuity,
Blue OL
Yellow OL
White 904 nanofarade
Black 4.405 Mohm

 

[koalar]

Let's stop

Your mixing up B CAN networks with C CAN networks

The normal 60 ohms network everything measures just fine, eventually

120 ohms with one end disconnected, the extra 5 ohms is just resistance in the wire, everything tests as it should up to the BCM, this is where the network stops, it does not go to the OBD port at all, Fiat chooses to use the pins for a different network

I have no idea what we are measuring on the BCM the board is multi layered I don't know where all the pins go we are only going to end up with useless information

I would be nice to get a closeup photo of each side while it's now apart to see if anything jumps out, we really didn't need to take it apart, only needed the resistance between pins 11 and 12 of the BCM originally

 

[RDM1]

Alright but i just wanted to mention that these pins that i mentioned on the obd port, i measured them on the bcm got 7 mega ohms then it went back to OL I'll send you a picture taken by my phone if it's not good I'll have to wait for my sister to come back with her iphone and then I'll sen you a better shot of it

 

[RDM1]

There ya go

 

[RDM1]

Clear enough?

 

[koalar]

Can't zoom in very far

But what I can see looks okay


Could do with a bit more detail

Here

Then I think it's time to close it back up

Well it's now understandable where you want me to focus on

 

[RDM1]

But if the BCM is fine we're going back to the car?

 

[koalar]

But if the BCM is fine we're going back to the car?

Be worth post a close up of the areas I circled in photos above, while it's apart

This is what I am looking at

If I zoomed in on similar component

From a board in front of me now

We can only work with the information given

 

[RDM1]

Alright tomorrow morning

 

[RDM1]

Half half hour they're good if not I'll send a picture of where you asked me to focus on

 

[koalar]

Half half hour they're good if not I'll send a picture of where you asked me to focus on

Looks good

Only place of doubt I can see is on this component

I take it the dark patch bottom centre is dust and brushes off

 

[RDM1]

Probably a shadow looks perfectly clean

 

[koalar]

Looks good to me to

There's nothing left to easily check here

Might as well box it up and put it back in the car

 

[RDM1]

What's next then? If the resistance is ok on both the car and BCM???
