i have had this issue with the car since i replaced the ecu (i guess, i didnt have a scanner when i had the original ecu). a battery charger at work took a crap when i was charging the battery on my car when i first got it. the result was a fried ecu. since then i got my scanner (VAD mobile) and i can only connect to the engine ecu. i cannot connect to my abs, trans, or airbag ecu. is it a possibility the ecu needs to be re-flashed? or is there something i can do on my end, such as change a basic setting in the ecu or recode something?
