Post Won't talk to ECU?
on: October 10, 2021 (GMT)

Please can someone help?

I’ve tried two different adapters (low profile bluetooth ELM327 ones) and it used to work fine before.

I believe it’s KWP2000 protocol

I’ve tried changing different settings. Could I have damaged a pin or something?

It connects fine to the adapter itself and the adapter has flashing lights at the top although unsure what they indicate.

This usually means that the adapter is not able to see the ECU in the vehicle (or the vehicle doesn’t support OBD2)

If it’s been working before, then it’s likely that the adapter has failed on the protocol the ECU uses(not uncommon if it’s an ebay clones – there are several protocols, using different signalling methods and sometimes adapters are faulty on one or more from the start or go bad over time)
