The P38 diagnostics is not readable by anything other than Test Book, Black Box, or Autologic plus the dedicated EAS only software. When diagnostics are used, the facility is needed to read AND clear faults. Hand held scanners are a waste of time and money on a P38. There is no way of doing it on the cheap unfortunately, other than the EAS software.
No doubt someone will come along and say that they have bought an OBDII scanner that does everything for £50 and the ££££'s sign will tempt people to part with their money. If such kit was available, do you think I would have spent £2 grand on the kit I have???? I am sure that other members on here with Rovacom etc. will confirm what I have said.
