Has anyone had this error message before ?

I have checked :

Main battery
Key fob battery (replaced)
Error Codes (none)

The only thing i could try next is disconnect the battery for for a period of time and reset everything

but I'm trying not to do that because (and i think its possible what the problem is) I have a Viper alarm fitted 4 weeks weeks ago, and its been fine, and its still fine, no problems at all anywhere. just an error on the dash display


Id would like to ask motors for ideas

Thanks
 
I wonder whether it's the same issue we had with our 2019 Mazda CX5? This manifested itself as "Key not detected" on the dash when pressing the start button. We had to have a whole new keyless entry system fitted to fix it.

I'd be talking to whoever installed this to start with, seems a little too coincidental that you've installed an aftermarket alarm and now the keyless start is playing up.

i did that, they said its keyfob battery
I've changed it, no difference, so i was going to get back to them again, but i thought i would post here first

at the moment it starts fine, the dash hasn't said this as of yet though
 
According to Copilot search, it could be a Faulty Brake Pedal Sensor. If you haven't already try pasting 'Why does my Mk4 Mazda 3 say "Push button start Malfunction?"' into Copilot as there are some other things too.

from your clarification to rilot it is succeeding to start despite the error ?
did you try jump starting it as well though, to give battery some potential help, in case elecronics was thinking battery was marginal - how had you tested it otherwise ?

[is the viper alarm spliced into the starting circuit somehow, or much more elaborate somehow communicating on the canbus]
 
Aftermarket alarm...

Almost certainly that is going to be the issue. More trouble than it's worth tbh.

Could be clutch or brake pedal switch? (If you need to hold one or the other during starting)

Push brake pedal to start . Might see if I can change the sensor that lives where the break pedal arm is as they are cheap enough

Surely you can bridge the connector plug's male or female pins that the sensor goes into, and then see if it fixes the issue? Then you don't need to risk buying a sensor that you might not need?
And the obvious bonus of knowing straight away if that was the cause/fix?
