Are there any cheap fault code readers on the market?

Are there any cheap fault code readers that do not need the ignition to be on? As my fault locks out the push button start on my Mazda 6 so I cannot switch the ignition on to power up the standard code readers.

There are so many on the market that it really depends on how often you will use it and how much info you need. Given your fault we would suggest that you get a good garage with up to date OBD equipment to check this fault out.
