DESCRIPTION
The display and navigation module display receives a vehicle speed signal from the combination meter assembly and information about the GPS
antenna, and then adjusts vehicle position.
The display and navigation module display stores this DTC when the difference between the speed information that the GPS antenna receives and
the SPD pulse received from the combination meter assembly becomes large.
HINT
* A voltage of 12 V or 5 V is output from each ECU and then input to the combination meter assembly. The signal is changed to
a pulse signal at the transistor in the combination meter assembly. Each ECU controls the respective systems based on the
pulse signal.
* If a short occurs in any of the ECUs or in the wire harness connected to an ECU, all systems in the diagram below will not
operate normally.

(a) Enter the "Check GPS & Vehicle Sensor" (Vehicle Sensors) See: Accessories and Optional Equipment/Navigation System/Testing
and Inspection/Initial Inspection and Diagnostic Overview/Navigation System (for DVD)/Operation Check.
(b) While driving the vehicle, compare the "Speed" indicator to the reading on the speedometer. Check if these readings are almost equal.
