ASCD Steering SwitchINFOID:0000000009462087
ASCD steering switch has variant values of electrical
resistance for each button. ECM reads voltage variation
of switch, and determines which button is operated.
Information DisplayINFOID:0000000009462088
The operation mode of the ASCD is indicated on the information display in the combination meter.
ECM transmits the status signal to the combination meter via CAN communication according to ASCD opera-
tion.

SYSTEM DESCRIPTION
This system improves engine operation when the air conditioner is used.
Under the following conditions, the air conditioner is turned off.
• When cranking the engine.
• At high engine speeds.
• When the engine coolant temperature becomes excessively high.
• When operating power steering during low engine speed or low vehicle speed.
• When engine speed is excessively low.
• When refrigerant pressure is excessively low or high.
