Honda civic 10th generation turns off while driving after giving immobiliser warning on meter

Make: Honda
Model: Civic oriel 1.8
Year: 2019

Car ignites normally. After driving a few kms, key alarm starts ringing and push button starts to blink in intervals leading to car turning off completely while driving. I checked with Honda and they were not able to identify the issue even after connecting it with their scanner.

I connected with my local mechanic; he checked it with the scanner and was able to provide a fix by cleaning the push button relay placed below steering rack above brake pedal. Issue went away for some time, but now it's back. From the past fix it seems like relay might be malfunctioned but I might be wrong. Anyone else faced such issue? If anyone did or knows about this do reply. Thanks.

P.S: There is no issue with key

there is a trick to check the exact issue
But you had to have the obd scanner connected when the error happens
it will record the error at that time and gives the report
But it happened to be once during the rainy season, if i park the car in the watery area
but goes away once car is dry etc

Better to check from scanner. Might be sensor malfunction .

Did you wash car engine with pressure water ?

FYI: I got the wiring checked; the culprit was improper current supply to engine start/stop button, and that was because of a faulty tracker connected to it. The tracker was installed by the previous owner; he neither informed me about it nor he cared to removed it before selling.
