Android Smart Phone

Torque app (mobile application, you can download it before starting the job)

Turn on the ignition to contact ELM327 code scanner.

(No need to start the ignition but you can do just in case)

All right, it reminds me No fault codes stored in ECU

If you have fault codes in ECU, you can clear them here

And you can search online for solutions. Of course you should have your phone connect to internet.
