A/C Check

A/C Check:




Troubleshooting:




A/C CHECK
For AC/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 C15 and at this moment when A/CON switch is turned ON, voltage is supplied to connector C5 at 9 V or more.
Thermistor 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.
