just as described
A really easy to use tool
JW_Redlands•November 10, 2017
A really easy to use tool, and priced right. A must have for proper diagnosis of SCR fault codes on newer diesel engines.
I like the idea of checking the fluid
Bill•October 8, 2017
Works as advertised. I like the idea of checking the fluid; perhaps a bit OCD, but worth the peace of mind.
