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