Not getting trouble codes about cardash HOT 3 CLOSED

Jiten,

I'm sorry, but this isn't something I'm going to be able to do any time soon. I simply don't have the time available to attempt to write and debug any code for this.

I would start on Page 12 of the ELM AT documentation: https://www.elmelectronics.com/wp-content/uploads/2016/07//ELM323DS.pdf

Looks like you should be able to send a command of 01 01 to get a list of how many trouble codes/which PIDs have trouble codes set. You should be able to send a 04 mode command to reset the codes and lights as well.
