Note

•  Immediately after the electric thermostat heater is energized, the heater is in a heated state and the resistance does not stabilize. Wait for a sufficient time before measuring the resistance again.

2.  Disconnect the electric thermostat heater connector. (See ELECTRIC THERMOSTAT REMOVAL/INSTALLATION [SKYACTIV-X 2.0].)
