Technical '06 Panda crank sensor issue.....
I does not worry me, the second time you turn the key is different, your car is different to mine but it's a different ECU, dash and Body computer
What is concerning is the persistent lack of RPM, occasional over temp
All sent from the CAN network
Unplug the ABS and see if anything changes

Did clean the 10mm bolt on the ECU and moved the ground to it and negative battery terminal

Alright then gonna go through with it tomorrow morning although the abs has always clean but it's worth a shot i guess

Doesn't this 3 blinking mean that the immobilizer is the one preventing startup?
As long as the light goes out the ECU has accepted the CODE sent the reply back to the body computer and the body computer tells the dash to switch the light out
My understanding is if the lights out all is good
It's only check once at ignition on as far as I know, but I could be wrong on this

But why after the failed startup attempt does it blink 3 times? Isn't it a sign that the immobilizer is the one preventing the start?
Light is on permanently if the key can not be read
Light off, immobilizer off is my understanding

What i mean it's the car didn't do that when it used to run i take this as a sign but i don't know what it does mean it would be much simpler of we could get the run without the immobilizer emergency code but i don't know how to get it

My dad went to fiat official service center when i got the car 5 years ago aiming to solve the coil issue that wasn't known and passed 3 mechanics and wasn't caught until i solved it myself anyway when my dad went to them, they mentioned that the 2nd gen of panda have been fully removed from their system so I'm clueless as to what other options i have to get it as a test
The CAN network is daisy chained
Cutting it the ABS may stop the immobilizer working
The backup system should still work, maybe
But at least it gives us an easy place to take some measurements

Alright then ripping the abs loom tomorrow morning then but after that what? Try and crank it?
Turn the ignition on and see if the immobilizer light goes out
Only if it goes out is it worth cranking

Hopefully have pulled a wiring diagram that a close match as none fit your car exactly
With the battery disconnected
Resistance between pin 15 and 26
Resistance between pin 14 and 25
Resistance between pin 14, 15, 25, 26 and ground
Resistance between pin 14, 15, 25, 26 and battery +

That's a shame I can't find any diagrams that match your wiring
We will have to test the CAN another way
Does the immobilizer light go off with the ABS disconnect

IIRC the Immobilizer light would blink on my '06 100HP If I put the car in MAR, but waited longer to actually crank it (say a minute + or so). But it always started since the code was already recognized.

Sorry for ghosting out it was a very busy day anyway after opening the ignition immobilizer light went out as it usually does after 2 seconds

That's the dashboard now shall i try cranking?
With the ABS still disconnected
Clear the codes
Crank the engine a few times
Read the codes, you will probably get some network errors as we have broken the daisy chain
Off the internet most of day
We can test the wiring for the CANBUS at the diagnostic port
Battery disconnected
Resistance between both pins
Resistance between each pin and ground
Resistance between each pin and power
The third party radio does it go off with the ignition
Does bit have a canbus adaptor fitted
