Default New JB4 Install, hazards staying on. - 01-20-2022, 01:16 PM

Hello all,

I just recently installed the JB4 with the MHD Back End flash. After flashing I was getting the Fuel Sensor error code so I replaced that but now the hazards stay lit on the dash at all times. If I do a pull it no longer goes in Map 4 but the Hazard Lights do not go away even at idle. If I get on the gas a little the lights will go away but come right back as soon as I let off the throttle.

Sounds like you set your shift light too low. What is your steering wheel menu 3 set to?

I am going to set the JB4 to map 0 and then flash MHD back to stock then enable JB4 and flash BEF. Might have done it out of order

Menu 3 is set to 6200. I haven't touched that since I installed JB4.

I think MHD has a setting for shift light as well. Maybe you overrode the JB4 setting when doing the backend flash?
