Help..JB4 code deleting...

kelvin2010 · 12-06-2011, 11:01 PM

Hey guys,

I am going to take my car into service because the passenger seat sensor doesn't work well.
I want to clear all the codes before I put my car into service to avoid any chance to get my warranty voided...
I have been searching around, but there is no instruction about how to deleting the code, but only reading the codes...
Can you guys please give me some help?
Thank you!

After chose that 1-2 on the tach and speedo, then I can shut down the car like usual...And unplug the JB4 from the ECU bay?
Thank you!

That's what I do right before I shut it off to take out the tune....never had a problem and I've had the injector recall w/ software update done.

How would I know the JB4 has cleared all the codes or not before I shut the car down?

I guess the only way to know for sure would be to have a bt scan tool but I just delete them and after the blinkers flash the 4 times I turn the ignition off and go from there. It's worked for me so far after a half dozen service visits and a couple misc. visits (i.e. injector recall, adaptive headlight error, etc) They didn't even say anything about having the LUX in there when the headlight malfunctioned haha

After the delete it then does a read. If you get 2 flashers followed by 4 flashers there are no codes. It's all in the documentation on BMS' forum.

Thank you guys!
Do I have to turn it to the "stock mode" before I delete the code?
Thanks!

By the way, where is the BMS forum? I could not find it on BMS website...
thanks!
