yes you can. first disconnect battery and remove horn relay from fuse box under hood.next lock the drivers door with the key.. now replace that 100 amp battery fuse. hard to find might have to go to dealer. replace that fuse the reconnect the battery. next open drivers door with key and start the engine. once its running go back and replace that horn relay you removed and shut the hood...good luck. did this on an accura just the other day myself!!
The security system thinks that something is wrong and is sounding the horn and flashing the lights. This is because the system had no battery power. Unlock all the doors, put key in ignition turn all way except to start the engine. remove key from ignition and lock all doors, This may reset the security system.
Some cars have inline fuses in the battery cables and have multiple connections for components making one get power and others not. If all your fuses are good, the next thing to look at is the electrical part of the key switch. Usually there is the mechanical part with the tumbler, and the electrical part.
Check these fuses again:
In the Power Distribution Center (in the engine compartment, left fender panel) Fuse #3 (20 Amp) Fuse #7 (40 Amp), Fuse #12 (20 Amp) and in the Junction Block (on the left end of the dash) Fuse #1 (15 Amp)
Use a test lamp and make sure that these fuses have power. All of these fuses should all have power at all times, regardless of ignition switch position. If they are all good and have power, then you probably need to replace your Central Timer Module. All of the circuits you listed are dependant on this module for operation.
The Central Timer Module is located at the left kick panel.
Central Timer Module System
The CTM is available in a BASE or a HIGHLINE configuration. The BASE and HIGHLINE CTM provide the following features: • Battery saver functions for exterior and interior lights • Cargo lamps chime warning • Courtesy lamps • Dome lamps • Dome lamp defeat • Door ajar switch state • Fog lamps • Headlamp time delay • Intermittent wiper controls • Low and high beam head lamps • Optical horn • Park lamps
In addition, the HIGHLINE CTM provides the following features:
• Central locking • Door lock inhibit • Driver door unlock • Enhanced accident response • Horn chirp • Optical chirp • Power door locks • Remote keyless entry (VTSS) • Remote radio
Check fuse for horn and for dash lights. If the interior lights work then suspect dimmer switch for the dash lights. If you press the horn button do you hear a click under the hood or inside the car? If you do not then the fuse is blown and if the fuse is good then the relay may be suspected bad. If the fuse is good and the relay clicks then suspect the horn to be bad. If fuse is blown and you put a new one in and you push the horn and the fuse blows again, then disconnect the horn before replacing the fuse again. Then push the horn button and see if you hear the relay click if you hear a click the the horn is bad or wiring butmost likely the horn. If you have the horn unplugged and the fuse is good and you push thee horn button and no relay click suspect the horn button to be bad. Hope this helps.
Maybe horn became unplugged. Put 12 v power to horn make sure horn works. Put test light on terminal on horn have someone press the horn button, if light comes on and horn does not blow you may need new horn. if light does not come on you may have bad contact at horn button, blown fuse, broken wire, bad horn relay or possibly just a bad ground.
Just had the same problem with my '05 van. I put the Master Switch in the off position. I pulled fuse #7 on the driver side sub panel, located just above the engine hood release. I then disconnected the neg. terminal on the battery. I manually opened the pass. side slider and closed it.
I reconnected the battery and replaced fuse #7. I put the master door switch in the on position. I activated the auto door switch, and it worked.
