Turn off the ignition.
Measure the voltage between Yellow/Blue (+) 22 and Black (-) 32 pins.
If there is battery voltage, then the Bat power source is normal.
If there is no voltage, then you should check fuse No.1 (10 A) in the relay box under the hood.
If the fuse is normal, then you should repair the break in the Yellow/Blue wire between fuse #1 and terminal 22 of the control unit.
If the fuse is blown, it should be replaced.
