Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
Hello, I will try my best to help you with your concern. Let me look at the schematic and get back to you.
first do you hear any kind of clicking noise when you press the horn pad? Do the flashers do anything? light up once? steady on?
Is there anything else not working? chime? key in buzzer?4
has there been any kind of work done to the vehicle recently?
sorry I'm not in Australia. I'm set up to do phone calls.
the horn relay is located in the TIPM which is the main fuse relay center under the hood. I'm having a difficult time find a picture of the exact location of the relay but it should say it on the back side of the cover.
check all the inputs and out puts to the relay.
with it being a Mexico model and unusual who knows, you can up load a photo right on the thread here and I can open it and look at it.
you are correct I don't see any relays on top just feeds for relays. that means the relays are internal in the unit and if there is an issue the entire TPIM has to be replaced,
it is going to be difficult to diagnose this system over the computer.. I will provide you a wiring diagram closest to your model and you will have to check several points along the path to determine where the voltage is lost
1. Check for voltage on the Dark Green/Violet wire at pin 19 of the C7 connector at the Integrated Power Module (IPM).2. If no voltage, either a bad Front Control Module (FCM) or an open internal circuit in the IPM.3. If voltage is present, remove the FCM and check pin 10 on the FCM to IPM connector for 12 volts.4. Ground pin 10 to see if the horn works.5. If no voltage on pin 10, the internal circuit in the IPM is open.6. If no circuit problems are found, the FCM is faulty.

might be a chance you installed a fuse or relay in the wrong spot. hopefully you took a picture of the panel before you removed fuses.
The FCM and the IPM are one and the same. they are integrated in the fuse panel, so if it is faulty the whole fuse panel would have to be replaced.

researching the flashers a little more, according to what I have read the flashers are controlled by a electronic circuit board built into the instrument cluster. The flashes are computer generated. Not much information about checking it. I can try to find a wiring diagram for that system as well.
