Because some have found significant discrepancies between the OBD II data and the climate display, I have not had any confidence in the readout accuracy of the climate panel “hack”; we go by reading the actual coolant temperature over the OBD II port using either a quality scan system or a data logger, which has been confirmed accurate.
