Ensure that the fault finding tool is not the cause of the fault by trying to communicate with a computer
on another vehicle . If the tool is not at fault and dialogue can be established with another computer on
the same vehicle, it may be that a faulty computer has disrupted the fault finding linesK and L.
Proceed using successive disconnections in order to locate this computer.
Check the battery voltage and carry out the necessary operations to obtain the correct voltage (10.5 volts
< U battery > 16 volts).
When communication is established, deal with any faults which may be declared.
