Using the FREE OBDSA Scantool Software, or any other generic OBD2 software,
it allows you to :
Read diagnostic trouble codes, both generic and
manufacturer-specific, and display their meaning
Clear trouble codes and turn off the MIL
("Check Engine" light)
Display current sensor data (depending on your vehicle), including: Engine RPM Calculated Load Value Coolant Temperature Fuel System Status Vehicle Speed Short Term Fuel Trim Long Term Fuel Trim Intake Manifold Pressure Timing Advance Intake Air Temperature Air Flow Rate Absolute Throttle Position Oxygen sensor voltages/associated short term fuel trims Fuel System status Fuel Pressure
Please note :Even though this interface is compatible with all OBD2 Compliant vehicles,
all South African vehicles are not OBD2 compliant,
as a result it may not work with certain South African produced vehicles. From experience with
South African users, we know that it does work with the following makes in South Africa :
Mercedes Benz,petrol BMW's, Ford , some Volkswagens , some Audi , Subaru , Mazda ,
Jeep , Chrysler, some Toyotas,some Isuzus, Porsche
Hyundai, KIA , Mitsubishi, some Volvos, Peugeot, Citroen
It will also work on most imported cars.
It does not work with most :
Diesel BMW , Opel , Nissan,Land Rover,Late model Volvo (V50 etc), Renault
Makes not listed have not been tested.
We have not been able to test this interface with every
model of every make in South Africa and the above list is
based on the cars I've tested personally. In general if it
works on one model of a make it works on the others,
but there are exeptions.
So really the only way to know for sure if a car is
compatible is to plug it in and test it!!
The ELM 327 will perform all OBD2 system functions
Which include :
It will allow you to read and reset OBD2 Fault codes (mainly engine) , read selected engine sensors in real time
And clear the “Engine Malfunction” warning light.
It will not work on non-OBD2 cars,
It will not access non-OBD2 modules (ABS, airbags etc)
and it will not reset service intervals or service lights , or any other warning lights
