INSPECT COMBINATION METER ASSEMBLY
Check speedometer operation
Note
The combination meter assembly receives the vehicle speed signal from the brake actuator assembly (skid control ECU) via CAN communication. Therefore, perform the following inspection referring to values on the Data List of the brake actuator assembly (skid control ECU) because it is the source of the vehicle speed signal.
Data List values of the brake actuator assembly (skid control ECU) are used for this inspection. Therefore, make sure to perform this inspection after confirming that DTCs are not output.
Warm up the engine.
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Put the engine in inspection mode (maintenance mode).
Enter the following menus: Chassis / ABS/VSC/TRC / Data List.
Read the Data List according to the display on the GTS.
