ELECTRICALLY HEATED SYSTEMS

Heated Mirror Relay
A button located on the HVAC control head controls the Heated Mirror Relay, which is located in the IPM. The HVAC control will ground the Heated Mirror Relay Control circuit to energize this relay. The relay control circuit is continuously monitored for certain malfunctions that the HVAC will report as DTCs.
