Is it technically feasible to rewire hazard button in steering wheel?
I drive a 2018 Honda Jazz VX MT.
BHPian Arwin07 recently shared this with other enthusiasts:
I want to have a ‘hazard button’ on my steering wheel of Honda Jazz.
Part 1. Why I use hazard light and why I want it in the steering wheel?
Part 2. Is it technically feasible to rewire a button in steering wheel.
Part 1: Why I use hazard light?
Let me quote this thread to begin my case.
https://www.team-bhp.com/forum/stree…-lights-2.html
I drive a lot in highways around Chennai and I find myself stopped in the middle of highway because of traffic pileup, sudden cattle crossing, two wheelers or pedestrians crossing the highway. I am a sitting duck in the highway and indicate hazard light so that vehicles around me notice and stop in time. Common from Tada- Chennai bypass- Chengalpattu -Tindivanam.
Other use case is in speed bumps and barricades in highways, I flash hazard light for a few seconds to indicate ‘I am going to slow down, so kindly don’t rear end me, thanks.
This was a recent use of hazard light, where once a cow started to cross the road, I flashed hazard light to warn the cars behind me. A Swift slowed down and avoided hitting while a Creta hit the cow.

Where I don’t use hazard lights:
To indicate to others that it is raining.
To indicate that I am driving straight in a junction.
Now that we have established why I use hazard lights a bit more frequently than usual, it would be convenient to have the button on steering wheel rather than in the middle of the dashboard. I understand that it is because front passenger also has access to the button.
Part 2- Is it technically feasible to rewire hazard button in steering wheel?
I drive a 2018 Honda Jazz VX MT. Attached is a picture of the steering wheel:
The steering button console has a centre button to choose the source of audio- bluetooth, AM, FM. I never use this button as I have Android auto in my Samsung mobile which I mount in a mobile stand thanks to this thread.

My car is due for service this month. Is it technically possible and safe for Honda service centre to rewire Hazard button to this ‘Source’ button in steering wheel that I never use?
Before talking with service centre engineer and technicians, I would like the esteemed opinions of fellow TeamBHPians.
Thank you.
Here’s what BHPian Jeroen had to say in this matter:
I doubt it. That switch on your steering wheel is unlikely to be a regular switch. It provides its input on the (CAN) bus. Its probably the BPM (body Processing Module) than translates its signals into various outputs.
Not sure if the hazard lights are controlled by the BOM as well. I seem to recall they need independent circuitry from the rest of wiring. If it is done via the BPM you need somebody to hack into the BPM.
I doubt an official Honda service centre would be entertain such thoughts.
Why don’t you just ask them? Who knows.
Just remember there is a reason the hazards are controlled via a separate switch away from the steering wheel

Meanwhile here’s what BHPian ajmat replied:
Hazard warning lights are usually used for warning when stationary. In the UK, the Highway code dictates that they should be used while stationary. However, many of us (including me) use them in anticipation when a sudden stop is required.
Frankly, the switch is within arms-reach in most cars and it is easy to flip the switch. This should be the last resort.
The best way to deal with such hazards requiring a sudden stop is to control the traffic behind you.
1: Read the road ahead
2: Anticipate and slow down
3: May be and again may be activate Hazards just before stopping.I rarely use my hazards.
