A/C Check




Troubleshooting:




For A/CON output, blower must be basically operated. When blower speed 1 is selected, blower relay is turned ON and voltage is supplied to point "A".

When the supplied voltage at point "A" is entered into control connector pin 3 and at this moment when A/CON switch is turned ON, voltage is supplied to connector pin 11 at 9 V or more.

EVA sensor value determines whether the input power at point "B" is supplied to point "C".

The state of ON/OFF of triple switch determines whether the input power at point "C" is supplied to point "D". Finally when the voltage is supplied to point "D", engine ECU determines whether A/CON and CONDENSER FAN turned ON/OFF.
