Correct time may not be displayed.

After the power is turned on, the system
always takes some time until GPS positioning
becomes possible. (The GPS receiver starts
positioning without re-collecting the whole sat-
ellite information when it judged the data
stored in the receiver is correct.)

Correct time of error occurrence may not be
stored in the ″

Perform self-diagnosis.

When the NAVI control unit is judged normal by self-diagnosis,
the symptom may be intermittent, caused by strong radio inter-
ference.

Revision: November 2009 2006 QX56

BCM is activated with low current consumption mode.

CAN communication is not active.

When CAN communication operation is detected, it switches to CAN communication status.

When a state of the following switches changes, it switches to CAN communication state:
–Ignition switch
–Key switch (insert)
–Hazard switch
–Main door lock/unlock switch
–Front door switch (LH, RH)
–Rear door switch (LH, RH)
–Back latch (door ajar switch)
–Glass hatch ajar switch
–Combination switch (passing, lighting switch 1st position, front fog lamp)
–Keyfob (lock/unlock signal)
–Front door lock assembly LH (key cylinder switch)

When control performed only by BCM is required by switch, it shifts to CAN communication inactive
mode.

Status of combination switch reading function is changed.
