The navigation system diagnostic software
has a SELECTION screen that is unique
to any previous system.
The choice,
1 - Start diagnosis
again,
means to start the diagnostic
session (either the first time or restart a
fresh diagnostic session.)
2- Sensor test has already been
carried out, reassume diagnosis.,
means to resume the diagnostic
session. This selection is used when
you have first started a session and the instructions on the DIS screen request that you
disconnect the vehicle and bring it outside for a sensor check or another field test of
some type as described in the diagnostic pages. When you return to the DIS, Select
#2 to resume the diagnostic session started previously.
The Navigation Service Functions contains
calibration data screens to review the
vehicles present state of calibration
(calibration status list). The calibration data
(#2) is set up for E38 vehicles only at the
time of navigation system introduction.
Calibration data of wheel-sensor
calibration provides a printout page of the
vehicles actual distance to wheel sensor
pulse. This screen will prove helpful when
dealing with the technical hotline if
additional data is requested from them on
wheel sensor calibration data values.
