5.1 ANGLE SENSING ERROR - FLOW CHART
Angle Sensing Error
First, verify the angle displayed through the console by
using the sensor output screen.
Press the info
button twice
Angle sensor
is functioning
correctly.
Angle sensor
range values:
4500mV at 0°
2500mV at 45°
500mV at 90°
Does the displayed
value differ from the
actual value?
Open the cable reel
and locate the angle
sensor (right) and
CAN-Bus converter
board (left).
Verify that the sensor is
being supplied with 5V
by measuring between
pin 5 (GND) and Pin 1
(+) of terminal X21.
Is the voltage
between the
range of 4.75
to 5.25V ?
Replace converter
board
If unplugging the angle sensor made the voltage return to
the acceptable range, replace the angle sensor. Follow
procedure for angle sensor installation and calibration.
