PROCEDURE
1. |
CHECK VEHICLE SIGNAL (OPERATION CHECK) |
(a) Enter the "Vehicle Signal Check Mode" screen. Refer to Check Vehicle
Signal Check Mode 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.
HINT:
The combination meter assembly receives the vehicle speed signal from the skid control ECU via CAN communication. Therefore, perform the following inspection referring to values on the Data List of the skid control ECU because it is the source of the vehicle speed signal.
OK:
Vehicle speed displayed on the "Vehicle Signal Check Mode" screen is almost the
same as the actual vehicle speed measured using the Techstream (See page
).

INSPECT COMBINATION METER ASSEMBLY (OUTPUT WAVEFORM) |
(a) Check the output waveform. (1) Remove the combination meter assembly with the connector 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
