DESCRIPTION The navigation ECU receives a vehicle speed signal from the combination meter assembly and information from the navigation antenna assembly, and then adjusts the vehicle position on the map. The navigation ECU stores this DTC when the difference between the speed information that the navigation antenna assembly receives and the SPD pulse received from the combination meter assembly becomes large. HINT:
WIRING DIAGRAM ![]() CAUTION / NOTICE / HINT NOTICE:
PROCEDURE
(a) Clear the DTCs. Body Electrical > Navigation System > Clear DTCs(b) Recheck for DTCs and check that no DTCs are output. Body Electrical > Navigation System > Trouble CodesOK: No DTCs are output.
(b) While driving the vehicle, compare the value of "Speed" to the reading on the speedometer. Check if these readings are almost equal. HINT: The combination meter assembly receives the vehicle speed signal from the skid control ECU via CAN communication. Therefore, perform the following procedure inspection referring to values in the Data List of the skid control ECU because it is the source of the vehicle speed signal. OK: Vehicle speed displayed on the "System Sensors Check" screen is almost the same as the actual vehicle speed measured using the Techstream. Click here
