Try leaving it disconnected for 10 mins or so. This will completely reset the ECM.We have tried that but when I installed the battery the horns went off. We disconnected the battery quickly to stop them. This is my sons truck and he stated that the red light is on on top of the dash. So I think the alarm thinks it’s on. Also key fob not working correctly so I think he needs to relearn the fobs to turn off the alarm. What do you think?????????????
well that was a quick diagnosis!jeeeez.We are being told via conversation with mechanics that the ECM is shot??????
Yep, what I thought, but then I've been victim of too many attempted dark-alley muggings by grease monkeys.well that was a quick diagnosis!jeeeez.
did you reverse connections while hooking the battery up?
if not ,then odds are your ecu is fine and your aftermarket alarm is the culprit.
if truck is all oem stuff then a simple battery replacement will not make it behave as you indicated.
Yep, cables too short and restrained; don't think it can be did....Isn't about impossible to reverse the cables on the battery?
Yes , BUT if you have a reverse term battery one can hear a kablamm and get a new fuse block after the smoke clears .I agree with everyone else. I'd just add that you should disable/disconnect the alarm to make sure its not the issue.
Isn't about impossible to reverse the cables on the battery?
Yes the part # of incorrect battery is same but an F or something simm. IF one is non attentive to the reverse polarity terms , kerblammm. Dead vehicle.well, funny you mention that....
