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

[koalar]

Yep that fine

Let's look at these two earth straps on the ECU

The main beam relay does not look to be fully home

It's not your problem though

Have you pulled every one out and pushed them back in the same place

The ECU really has been swapped in the past

Yeah i went and checked every single one of them but one at a time and of course each one was returned to its place probably didn't push that one all the way in.

Sorry my bad

 

[RDM1]

As for the ECU I can't be sure but not only it might be swapped but it might be inversed aswell can't be sure though unless someone that is absolutely sure about it

 

[RDM1]

I'll remove the ECU and tell you what I mean tomorrow because it's dark and hard to take pictures

Fuse F03 isn't fully home for some reason

This supply power to everything

Let's look at the contacts underneath

There should only be one black ground cable

I suspect one is either a bodge or should be fitted elswhere

 

[RDM1]

No no i mean the ECU the way it is fitted is probably rotated 180 degrees probably because of its back

 

[koalar]

Still need the voltage drop to the ECU aluminium housing whole cranking

It was the only only thing we measured that was wrong

Was the test wrong or is the problem here somewhere

Want me to remove the ECU from its place and test it mid air?

 

[RDM1]

Because the back cover is probably touching with its fixing location because as i told you it's probably rotated a half turn

 

[RDM1]

These are the 2 wires attached to the ecu case on the bolt we moved it to the upper left bolt but initially it was on the bottom left one

 

[RDM1]

See what i mean rotated half a turn? I'm worried that the ECU got fried because of that

 

[RDM1]

And about the fuse box everything is seated properly, double checked everything and they were all properly seated in their places and what seemed off were their plastic casings even the fuse

 

[koalar]

Almost certainly the ECU and body computer is fine

I wish I had the same layout even though mine is a euro 5 its wire completely different

Two grounds on the same place causes ground loops, it's not standard practice, the only time I have seen it is where one has failed and a second added

It looks to me like the both go into the wiring loom

I suspect one was somewhere else

Ok so want me to separate them?
And no, one goes into the upper loom and the second as you might have seen in the picture goes under the windshield to the chassis

 

[RDM1]

If it's bad to put them together I'll put one on the left upside and one on the bottom left side no biggie

but what about the ECU? Is it inversed? Or am i only theorizing stuff?

[RDM1]

This photo is taken how it is fitted just removed the 4 bolts and laid it down so i could properly take the picture and explain

 

[koalar]

Keep everything as it is for now and do a volt drop to the two earth points while cranking

 

[RDM1]

Wait a minute how do i do it for the one in the loom? Or want me to do it on the bolt after assembling it again?

Put it back as it was

I am fairly sure the one to the chassis has been added to fix a problem but will check the diagrams later

We had 0.8V between the ECU and the block, and 0.2V between the block and the battery

0.2V is good carrying 100 amps
1V is bad carrying less than 5 amps

Either the test was wrong or we have to investigate further
