Good first time experience with JSCAN

[HK1s]

Need to edit light setting, obviously I want the tazer mini but went jscan (so cheap). The security gateway plug location is brutal to say the least ? I got cuts on my right hand unplugging the 12+8 connector. There is barely enough room to reach the plug. I looped the SGW bypass cable around the metal bar under the steering wheel to hold it in place, not going to plug SGW back in till next dealer visit.

to make jscan work I got the following, after tax in Canadian dollars.
chrysler 12+8 cable $20
V-gate icar pro bluetooth 3.0 $28 (this only work with android)
jscan license $30

Everything worked smooth, the v-gate connects right up and jscan works flawlessly.

Actually all I really needed to do is change the DRL location because I got always running (fuse tap) halo in the new headlights, I have the sport s and only option is the auto transmission.
but here are some features I toggled:
1. Change DRL location to turn signals, the default was lowbeam headlight
2. DRL dropout enabled
3. Changed the Headlight lowbeam highbeam to LED type, default was halogen, this don't seem to make any difference for the oracle brand of light.
4. Disabled the 3 honk when leaving the jeep running, if the damn system only honk once I wouldn't be so annoyed. Nope this is hard coded and don't seem to work, not even leaving the seat belt buckled work.
5. Hood alarm, You have to pop open the hood once after toggling the setting to make it work. I wonder why this is a live function for tazer?

I always wanted a car mechanics scan tool. the tablet type used to cost a lot when I was little. Now only using a phone and bluetooth interface I can do a lot more?


There are some other things that Jscan are good at.
Headlight will turn on with wiper, a small mist will trigger my headlight and my dash go dark. Canada spec headlight switch don't have the off position. its auto or on! It gets tedious constantly adjusting the dash light dial.

Thing is when I check with scanner the "headlight with wiper" menu option is enabled? but I can't find it anywhere in uconnect, turns out its enabled but hidden trying to confuse me I see.

in order to get the "headlight with wiper" option to show in uconnect I have to disable the option wait for PCM to do a deep sleep cycle and enable it again, now I can see the option under lighting menu.


adjusting auto headlight sensitivity.
you can actually see the readings of the light sensor from modules -> body controller -> ambient light sensor. And adjust the auto headlight sensitivity. higher voltage means less light.

I would really like the JScan to be like VCDS. Most don't know but VCDS has been around for years and works with VW/Audi products. It does everything the dealer tool does and you can do coding for a multitude of things and diagnosis. I'd like if JScan had like VCDS. Where you have a dongle that plugs in the Jeep, then it'll work either plugging into a laptop or can be logged into your WiFi or just use your phone. They go from full pro to the enthusiast.

At work I use a Snap-On unit and it's amazing the diagnosis that it can do plus many other items. Costs a bunch but it's a tool for when you have a multitude of vehicles you have to see on a daily basis. Not just looking at codes but tests to determine what the problem really is (i.e. EVAP codes) then logging info (i.e. misfire counting).

+1 for JScan

Also I really miss the functionality of VCDS on my last Audi. Things like smog check "readiness process" were invaluable. It would cycle the engine through all rpms and specific durations etc to check everything.

I agree. Plus I can recode a number of things. Just doing a more aggressive rear diff and throttle application was great. Removing all of the nannies on the radio (so you could change NAV things while driving as my wife wanted to do that while I drive but it was not possible.)

As for rediness. My neighbor had a 2000 Jetta. It would throw an intermittent code for the post O2 sensor (even after changing it). So, Id clear every code and go through the 15 minute thing to reset the rediness monitors. She'd take it to the dealer for inspection and emissions. It passed with flying colors for at least 15 years. Then the dealer must have caught on and then didn't fail the car but had 10 items that were things she needed to have looked at things like:
-oil is too brown
- tires are a bit rough
- Missing lower left piece of trim
- Brakes are at 50% but have not been changed in 10 years
-Sunroof needs to be cleaned and lubed

She was 87 at the time and I just helped her out because she was old and worried about her car (which all old people do). She drove that thing until she was 90 and then gave it to her grand son. The lady died last year at 95. At least, she had a reliable ride.

I'm a recent JSCAN customer. I used it to correct regearing and larger tires, as well as toggling fog lights on with high beams.

Everything worked first time perfectly. I simply used the manufacturer's published actual tire diameter and verified it against my GPS on straight highways using cruise control at 40,50,60,70, and 80 mph.

A bit off topic, but, to correct oversize tires, I had read on this forum that members were going to the extra step of measuring loaded radius from the ground up to the center of the wheel, specifically at the tire pressure they intended to use. My theory is that the unloaded circumference of the tire, at normal pressures, is the overriding factor in distance traveled per revolution. Not the "squashed" radius. Think about how a tracked vehicle moves. That was my experience. YMMV

Do like in cycling. Just draw a long line with chalk. Load up the vehicle, mark the tire on the sidewall at the bottom( plus do it on the street) and push it until the mark makes a full rotation. Then measure the distance.

With a bike, loaded vs unloaded, makes a difference.

Need some help. I'm having my JL regeared today at a shop. I'm going to use JScan to change gear ratio. I'm not real clear on the steps from the JScan documents and can't get a soild answer from anyone. Other than change gear ratio, is there anything else I need to do in JScan? The docs mention resetting the gear box, but it looks like that only applies to JKs. Any advice, tips on what all you had to do? Thanks!
