CHECK COMBINATION METER ASSEMBLY
Check speedometer operation
The combination meter assembly receives the vehicle speed signal from the brake actuator assembly (No. 2 skid control ECU)*1 or brake actuator assembly (skid control ECU)*2 via CAN communication. Therefore, perform the following inspection referring to values on the Data List of the brake actuator assembly (No. 2 skid control ECU)*1 or brake actuator assembly (skid control ECU)*2 because it is the source of the vehicle speed signal.
Data List values of the brake actuator assembly (No. 2 skid control ECU)*1 or brake actuator assembly (skid control ECU)*2 are used for this inspection. Therefore, make sure to perform this inspection after confirming that DTCs are not output.
*1: for HV Model
*2: for Gasoline Model
Warm up the engine.
