If voltage is 5v....
Keep the truck ON. Use ANALYZER MENU/
A2.5.1 ECR2 to show the counts when you turn the
steering wheel clockwise a
nd counterclockwise. The
counts should change smoothly and continuously as
you turn the steering wheel. Record the counts when
the steering wheel is in the neutral position.

Turn the truck ON. Measure the voltage be-
tween CA410-2 and CA410-4.
The correct voltage = 5 V.

Fact of the week

From 1912 to 1948, gold, silver and bronze medals were awarded for literature, architecture, sculpture, painting, and music as part of the modern Olympic Games. Art works were required to be inspired by athletic endeavors. After heated debate about their place in the games, the art events were eventually removed. The 151 medals awarded were officially stricken from the Olympic record.
