sensor fitted height sensor connector (sensor not connected), with respect
to vehicle body. • Voltage to sensor ground connection should
be ~0v • Voltage to sensor signal connection should be ~0v •
Voltage to sensor supply connection should be ~5v All
voltages should be within ± 0.15v. To check sensor operation
on the vehicle: Check for water ingress around the height
sensors, electrical connectors or shaft end. Check for
excessive movement in the shaft in all directions. Raise
vehicle (ideally on wheels-free ramp) until suspension on
corner under investigation is at rebound to gain access to
height sensor. Access may be improved by removing road
wheel. Carefully disconnect the height sensor link from the
upper suspension arm. Monitor the height sensor signal
voltage output for the height sensor under investigation.
Position the sensor arm so it is in the mid position and
confirm that the voltage is around 2.5 volts. Move the sensor
arm over the range ±40° around the mid position and confirm
that the voltage changes smoothly between around 0.2 volts
and 4.8 volts. If voltages are incorrect or do not change
smoothly then replace sensor. NOTE: For angles of movement
beyond ±40°, the sensor signal will clamp to a voltage of
~0.15v or ~4.85v, depending on position of sensor lever. This
is normal. When investigation is complete, refit height sensor
link to upper arm. If any fixings to the height sensor body or
mounting bracket were slackened or found to be loose or if a
height sensor was changed, the vehicle ride height MUST be
re-calibrated. Refer to the relevant section of the workshop

terminals and vehicle ground. B: Check for electrical continuity
between the two connectors for each of the 3 terminals.
Reconnect electrical connector at Control Module only. C:
Check voltages at terminals within height sensor connector
(sensor not connected), with respect to vehicle body. •
