Good morning,

I am writing to you about a problem on an old 188 1.2 8v 188A400 point

The car arrives in working order, the battery is replaced and upon starting the engine runs but does not start.

There were no short circuits in the assembly, the fuses, ECU power supply, injectors and coils were checked. no negative control signal is coming out of the engine control unit.

The reserve light on the dashboard flashes, the code light goes out correctly.

in engine ECU diagnosis we have 'P 0500 vehicle speed sensor (CAN)'.

On the other hand, there is no communication if you try to enter into diagnosis with a body computer.

We tried to physically disconnect each body supply for about 15 minutes but to no avail.

I thank you in advance.
