Hello my name is***** am an ASE Master Technician and I am glad to help you.

I do not see the alarm problem related to replacing the window switch.

Did you remove the door panel to replace the master switch? You need a scan tool to check for any codes in the security system. Have you tried using the key in all the doors and truck if equipped?

My drivers side window would not go up or down, so I had that fixed (and at that time, the door panel was removed then, but that was about 2 1/2 weeks ago. Well I recently broke a button on my master switch panel and I ordered a new master power switch from a Honda parts dealer and started having the problem only after that. But replacing the switch didn’t require removal of the door panel, we just popped off the piece, removed the old switch panel and plugged in and snapped the new part into place.

Does the keyless entry work?

Is the security light in the instrument cluster on?

the security light is on
Mechanic for Honda: Dan, ASE Master Technician replied 7 months ago

Ok great! with the security light being on it means that you have a diagnostic trouble code in the security system module. You need a shop, or a shop quality scan tool, to scan for codes in the security system. This will narrow down your problem. Once you have the code it will be possible to diagnose you issue that is causing the alarm to set when opening the door.

Your answers were clear and the diagrams were perfect. Dealer wanted $87 for an hour of labor and even I did it in 15 minutes.

EdUSA

HONDA PLATINUM was great. I really appreciate his help. I was ready to trade my new Honda until he told me to wait until I got 3,000 miles on it and my gas mileage would get much better.

SummerUSA

I took the Power Steering O-Ring service bulletin linked from JustAnswer to my Acura dealer, and not only did they no-charge the o-ring, they also replaced the power steering pump at no cost.

Gary RStevenson Ranch, CA
