DESCRIPTION
The navigation receiver assembly receives a vehicle speed signal from the combination meter assembly and information from the navigation antenna assembly, and then adjusts the vehicle position.
The navigation receiver assembly 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.

WIRING DIAGRAM
PROCEDURE
1. |
CHECK VEHICLE SENSOR (OPERATION CHECK) |
(a) Enter the "System Sensors Check" screen. Refer to Check GPS & Vehicle Sensors in Operation Check (See page ). |
|
(b) While driving the vehicle, compare the "Speed" indicator to the reading on the speedometer. Check if these readings are almost equal.
OK:
The readings are equal or almost equal.
OK |
REPLACE NAVIGATION RECEIVER ASSEMBLY |

2. |
CHECK COMBINATION METER ASSEMBLY (OUTPUT WAVEFORM) |
(a) Check the output waveform. (1) Remove the combination meter assembly with the connector(s) still connected. (2) Connect an oscilloscope to terminal C9-40 (+S) and body ground. (3) Turn the ignition switch to ON. (4) Turn a wheel slowly. (5) Check the signal waveform according to the condition(s) in the table below.
OK: The waveform is similar to that shown in the illustration. HINT: When the system is functioning normally, one wheel revolution generates 4 pulses. As the vehicle speed increases, the width indicated by (A) in the illustration narrows. Text in Illustration

CHECK HARNESS AND CONNECTOR (NAVIGATION RECEIVER ASSEMBLY - COMBINATION METER ASSEMBLY) |
(a) Disconnect the N25 navigation receiver assembly connector.
(b) Disconnect the C9 combination meter assembly connector.
(c) Measure the resistance according to the value(s) in the table below.
