Alpha OBD ability to read airbag faults

[JR]

Can anyone with Alpha OBD confirm if it can read airbag faults or do you need to buy additional adapters? I've read conflicting answers on this. I do know their website says

features

• active diagnostics and configuration procedures for various equipment controlled by engine, gearbox, body computer, climate control, ABS, airbag, code control and other ECUs. Service light reset, engine oil change, DPF regeneration and many more.
• electronic key and RF remote control programming

Then goes on to say

is recommended to purchase an adapter or set of adapters to be able to communicate to the Control units other than those connected to the pin 7 (K-line) and 6 and 14 (CAN high line) of the car OBD plug

Which control units are they referring to?




I have a very intermittent "service airbag system" light. It will sing a song 10 times in an hour and then go silent, sometimes for days or weeks at a time. It does seem to be increasing in consistency but my luck I'll schedule an appointment, drive it an hour to my nearest dealership and it won't be active. Already had this happen once when I took it in for a recall. I'm hoping to arm myself with a schematic (next on the list) and trouble shoot it myself.

Most cheap bluetooth OBD cannot read all the modules as they don't implement all the pins. OBDLink MX and MX2 can read all the modules but is quite a bit more expensive. ($70 vs $10) to use the cheap OBD readers you will need a switch box to connect to other buses.

Perfect, thank you.

Just bought the MX+. MX would have been sufficient but we will be car shopping for the wife in the near future, and it just might be a Fword
the + claims to be able to handle the new Ford MS-CAN.

I have the MX+. Works well.

Anyone got a link to these? I am looking to purchase but not sure where to buy from. There are changes I want to make to my ram and my wife's journey.

I bought mine from Amazon.

Then you have to buy the Alpha OBD app.
