Sometimes communication is interrupted when connector contacts become slightly corroded. Try unplugging and plugging in the scanner connector, 4 or 5 times and compress firmly.

thanks for the advice. ive done about a dozen scans over 4 days, still the same wont delete faults, looks like a trip to a mazda dealer.
