Power Supply

1. Switch ON the ignition and shift to 4x2 mode.

2. Switch OFF ignition, disconnect the connector

at the FAD actuator, Switch ON the ignition

then using voltmeter/multimeter measure the

voltages between



Pin B and Chassis ground: Measured voltage

= 0 Volts



Pin D and Chassis ground: Measured voltage

= Battery voltage (8 to 12 V)



Pin A and Chassis ground: Measured voltage

= 4 to Battery voltage.



Pin C and Chassis ground: Measured voltage

= 0 to 0.9 V.

If the voltage is out of the above mentioned range,

check for any short circuits or open circuits.

Reconnect the connector after rectifying the

problem
