the new Twin Scan II pro - vides diagnostic capabilities not found in other tools. It’s especially use - ful for diagnosing hard to find intermittent trouble codes. The motorcycle can be operated while the unit is installed. Under normal condi - tions (no trouble code), the unit will store data for the last hour of operation. If a trouble code is set, the unit automatically stops logging data 30 minutes after the code is set. This allows you to examine data before and after the code was set, even days later.
