[QUOTE="SlugSlinger, post: 3314219, member: 7248"] I bought this scanner to see why I had some DTCs on an old Jeep I bought. It is handy to find and clear codes after making repairs or sensor replacements. [URL]https://www.amazon.com/gp/product/B076XVQMVS/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1[/URL] Because its an old Jeep, I started making some upgrades. I upgraded the headlights with some old school e-code Hella headlight housings, upgraded wiring and some relays to draw power directly from the battery. What I didn't realize was the headlights are controlled by the ECU and are factory set to pulse via PWM. Well because I installed some mechanical relays, now my modification suffers and the lights look dim because the relay can't keep up with the pulse. To fix this, I was going to install some capacitors to level out the pulse. However, after looking through the app I bought to use with the scanner, I found I can turn off the pulsing instead of having to buy the capacitors. I turned off the pulsing and now have some good and bright headlights. I was also able to to program the low beams to stay on with the high beams. I can control a lot of things with the app. This includes locking doors, rolling windows down, and many other things.
