The What and Why
-OBD II Port, present in all new cars, near steering wheel.
Has diagnostic and status information.
ISO Standard.
Can access vehicle canbus through this port. Has more info. used by various systems in vehicle to communicate with each other.
CanBus has two types of messages (I think) - status and commands.
Ford uses two types of canbus - HS and MS. Need to rewire to read MS-CAN messages (commands are sent through this?)
The How
Cant use chinese ELM327 clones to sniff canbus messages. Need original ELM327. Difficult to get in India.
Also buffer issues with BT models
Purchased OBDLINK SX model from Alibaba. meeting requirements for HS-CAN.
Have also purchased an adapter, which will have to be modified to read MS-CAN.
Using terra term to sniff messages in windows. Linux might potentially be easier.
Using excel to analyse message dump.
NOTE: page will be made descriptive sometime in the future.
