I recently took the programmer off today and now the Red Security light blinks non stop and trailer brake
light flashes after I put the key fob in the ignition. Truck started up just fine before and now it wont even turn over
JA: Have you checked the brake fluid? How's the level and when was it last changed?
Customer: It looks good and changed about 4 months ago
JA: What is the model/year of your Dodge?
Customer: 2010 2500 Crew Cab short bed 4x4 6.7 Cummins
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Yes. Ive tried unhooking batteries
and I tried to put the tuner back on it to see if that would help but now I cant get it to work.
JA: Anything else you think the mechanic should know?
Customer: Not that I know of. It started just fine before I took the tuner off of it
