 DTC 2703 can be stored when the ignition switch is at ACCESSORY (I). With the ignition switch is in
ACCESSORY (I), the climate control unit is turned off
and the navigation unit loses communication and
stores DTCs. Therefore, there is a possibility that the
system is normal even DTC 2703 is stored. Check
system links (see page 23-297) with the engine
running, and if it shows normal, the system is OK at
this time. If not, do this troubleshooting.
