Component Description
The heat up switch is located on the lower side of the instrument
panel. This switch is used to speed up the heater’s operation when
the engine is cold.
When the ECM received the heat up switch “ON” signal, the ECM
increases the engine idle speed to 1,100 to 1,200 rpm to warm up
engine quickly.
This system works when all conditions listed below are met.
Heat up switch

ECM Terminals and Reference Value
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may damage the
ECM’s transistor. Use a ground other than ECM terminals, such as the ground.
