pretty much as per title running a g4+ on a customers R53 mini. every once in a while his external lambda controller doesn't boot up correctly and throws an error code. This in turn makes the oem dashboard check engine warning light come on. Which in turn stays on until a laptop is connected and the warning reset. looked everywhere but can't find any obvious way of turning of the output within the g4+ that triggers the warning light assuming it is within the canbus protocol. Does anyone know the settings that need changing to switch of the check engine light output?
