NAVIGATION / MULTI INFO DISPLAY: NAVIGATION SYSTEM (for DVD): B15C2: Speed Signal Malfunction
B15C2 - Speed Signal Malfunction
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.
