Sun Sensor Error; Power Transistor Error - SSANGYONG 2004 Rexton 2.7XDi Workshop Manual

Sun Sensor Error

Step
1. Disconnect the Sun sensor connector.
2. Place the sun sensor under the sun light and measure the current
between the connector terminals.
1
3. Place the sun sensor under the shadow place and measure the
current between the connector terminals.
Is the measured current lower at the shadow place?
Replace the sun sensor.
2
Is the repair complete?
1. Remove the controller with connecting the connectors.
2. Turn the ignition switch to ON.
3
3. Measure the voltage terminal A13 and B10 by backprobing the
connectors. (Sun light: 2.5 V, Shadow: 4.8 V)
Is the voltage equal to the specified value?
Repair open or short circuit.
4
Is the repair complete?
Replace the FATC controller.
5
Is the repair complete?

Power Transistor Error

Step
1. Remove the controller and disconnect the controller connector.
2. Disconnect power transistor connector.
1
3. Examine the open or short circuit between controller connector and
power transistor connector.
Is there a problem in the wiring or the connectors?
Repair the faulty wiring and replace as needed.
2
Is the repair complete?
1. Reconnect power transistor connector and FATC connectors.
2. Turn the ignition switch to ON.
3. Measure the voltage between ground and terminal B12 of the FATC
controller while changing the blower speed from 1 to 6 manually.
3
1st: 4.5 V
2rd: 6.0 V
3th: 7.5 V
Is the resistance equal to the specified value?
Replace the power transistor.
4
Is the repair complete?
Replace the FATC controller.
5
Is the repair complete?
