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

[RDM1]

Battery positive to alternator =0.28
Battery positive to starter=0.23

 

[RDM1]

Couldn't find a negative on them because apparently they use the ground to power themselves

There good at the time of testing

Correct they use the engine block already tested

 

[RDM1]

These are the values when i sent them (aka fresh results) and extremely accurate

 

[RDM1]

What's next? Because now battery and oil lights wont go away upon cranking

 

[RDM1]

And immobilizer still blinks after a failed starting attempt

 

[RDM1]

That's everything that are still obvious along with the faults on the bcm otherwise everything seems good

 

[koalar]

Do you have a spare key

Or

Two keys on the key ring

 

[RDM1]

No unfortunately my father never pressed the previous owner to give us the 2nd key

 

[RDM1]

But i used a key programming tool and the chip could be read normally and the BCM on the scan tool returned the key program as valid stating its numbers

 

[RDM1]

These are my live BCM data and the last 2 are to show the remote control of locking and unlocking

For reference, when the key is inserted but not being cranked, the immobiliser light turns off after a few seconds.
The battery and oil pressure remain lit until the car starts and then turn off immediately.

 

[RDM1]

That's true but the immobilizer light will flash 3 times with the 3rd lasting longer if you check out my previous videos i think at page 3 or 4 after the car fails to start but if you close the ignition then reopen it it function as it should once then goes out. Check my videos to understand what I mean

 

[MrMagoo]

... and the dialogic accumulator pressurises every time I open the drivers door.

 

[RDM1]

Same and it works normally or if you enter from the passenger side it starts building pressure as soon as you set the ignition into acc

 

[RDM1]

I'm suspecting something wrong with the BCM but got no idea what it is because it's acting weird and he's the one that allows or deny the starting of the car unless there's a bad wiring somewhere that can't take the big load upon starting or the ECU is fried and there's no symptoms of either of them

 

[MrMagoo]

You mentioned the crank angle sensor wiring was replaced midway down? Have you physically traced and checked this wiring?

 

[RDM1]

I did check it was burned about 2 inches before the sensor and the car was running fine but now without taking any possibilities i cut them both and replaced the burn pieces that were about 3-4 inches or so

 

[RDM1]

And there was rust starting to build up on the copper so i thought it was time to change them
