In my previous post I explained some of the vulnerabilities the factory security system my 2015 Honda Vezel suffers from. I also looked at some of the alarm options available and why I felt that the Vodafone Automotive 4822 alarm was a good option.
Here is the list of items I decided to install and how they all work together in the vehicle.
Shopping List:
- 8422 Alarm with Built-in Tilt Sensor
- 5375 Wired Battery Siren
- Defractive Ultrasonic Sensors in Black
- Standard Internal Siren
- ADR Card
- SCD40 GPS (transferred from a previous vehicle)
Programming Auxiliary Outputs:
There are many programmable options which I’ll list later of the post, but there are only 4 Aux outputs.
Here are my picks:
- Aux 1: Horn output
- Aux 2: OBD Protection
- Aux 3: Pager Output – Wired to SCD40
- Aux 4: Standard VFA Siren
Installing the new Ultrasonic Sensors
The new defractive ultrasonic sensors will only be suitable for small percentage of cars. My guess is that I’ll be installing them in less then 10% of my installs and the rest will still use the “A Pillar” sensors. I could have opted for the “A Pillar” ones in the Honda, but the novelty of something new was very compelling. Plus I’d get to be one of the 1st technicians to install them.
The installation manual states that the minimum distance between the sensors should be 10cm.
I considered fitting them at the outside section of the light pod in line with the lights on the honeycomb area. But surface is slightly concave and I was not confident that they would look flush.
I also considered fitting them in to the smooth plastic area that did not have the micro honeycomb pattern, but the sensors would be to close together.
The flat honeycomb section was the less risky option. An 11cm gap between them was good, and the plastic behind which needed cutting out was safe enough to trim.
The first sensor needed heaps of plastic ribbing to be cut away before drilling the hole.
Cutting away the plastic ribbing reduces the danger of the drill bit wandering off when drilling. If the sensors were not perfectly symmetrical it would be annoying to look at as it would stand out next to the honeycomb pattern.
Once the ribbing was trimmed I drilled a 18mm hole in an old piece of plastic to double check the hole size. I then committed and very carefully cut the holes in the lighting pod.
It’s really important to be Obsessive with these little details.
Speaking of being Obsessive, I love that there is a choice of black and grey for the new defractive sensors but… Why can’t the A Pillar sensors come in Black too?
The new plugs on the sensors make it impossible to remove the pods to paint them like I could on the 4600 Series of alarm. Now I have to paint them with the cables running through which is a pain.
High Security System – Light Mode
I’m aware that it is possible to do a RollBack RF Attack on the Honda (Another post I need do).
It’s also vulnerable to an All Keys Lost attack on the OBDII plug
A full explanation on how the High Security System works can be found here.
A post covering ways to protect the OBD Port will appear here soon,,,
Vodafone Automotive 4822 Programming Options
Full list of Auxiliary output options
- Horn

- Boot Pop (for remote version)
- Additional LED
- Pager
- CDL Open (for remote version)
- CDL Close (for remote version)
- Window Closure (may require extra parts)

Next level programming
On top of the list of Aux outputs there are a large number of improvements in the programming options for the 4822.
Siren Beeps and Hazard Flash
It is now possible to program how many many times the siren beeps when arming and disarming the alarm. The same can be done for the hazard with how many times the hazard lights flash.
Adjustable Input and Output Timing
Many of the parameters can have the timing adjusted, these include: High Security System (Grace Period), OBD Protection Timeout, Alarm Cycle Duration, Auto Re-locking Time, Dome Lamp Delay. Passive Crank Time. Window Closure Output.
Full list of Input Options
- Bonnet
- Drivers Door
- Boot
- Doors
- External Sensor
- Ignition
- PLIP Inputs 1,2,3,4
- Panic
- Driver Recognition Switch
- US Exclusion
- Odometer
- LIN
Input Options
With a CAN-Bus installation many of the analog inputs listed will already have been detected digitally, but for a PLIP or remote alarm there alarm become very versatile.
The Alarm memory has 20 different trigger input codes, which makes fault finding very easy
Ultrasonic Sensor Exclusion
Being able to turn the Ultrasonic Sensors off via a switch in a Motorhome can be very useful if you want to arm the alarm at night and sleep inside it.
Bonnet Switch Polarity
Most bonnet switches go to ground when opened, but some factory switches do the opposite. For vehicles that do not have the bonnet detected by CAN-BUS (I’m looking at you Toyota Hilux) I used to need an extra part. The 4822 has finally fixed this 🙂
