Test conditions
l  Fault in the Hall transmitter detected using the self-diagnosis
  Note
If the fault memory is consulted while the engine is not running or without first turning over the starter for at least 6 seconds, the fault Hall sender -G40-, no signal will appear even though there is no problem.
Checking process
–  Remove the connection from the Hall sender (ignition distribution).
