DESCRIPTION The combination
meter assembly receives vehicle speed signals from the skid control ECU
(brake actuator assembly) via CAN communication. The speed sensor
detects the wheel speed and sends the appropriate signals to the skid
control ECU (brake actuator assembly). The skid control ECU (brake
actuator assembly) supplies power to the vehicle speed sensor. The skid
control ECU (brake actuator assembly) detects vehicle speed signals
based on pulses of the voltage. HINT: Factors
that affect the indicated vehicle speed include the tire size, tire
inflation, and tire wear. The speed indicated on the speedometer has an
allowable margin of error. WIRING DIAGRAM CAUTION / NOTICE / HINT NOTICE: Tire size and air pressure: Click here Speedometer: Click here PROCEDURE 1. CHECK CAN COMMUNICATION SYSTEM (a) Check if CAN communication DTCs are output. Click here

REPLACE SKID CONTROL ECU (BRAKE ACTUATOR ASSEMBLY) REPLACE COMBINATION METER ASSEMBLY DESCRIPTION The combination
meter assembly and steering pad switch assembly are connected via
direct line. The multi-information display in the combination meter
assembly are operated using the switches of the steering pad switch
assembly. WIRING DIAGRAM CAUTION / NOTICE / HINT NOTICE: When
replacing the combination meter assembly, always replace it with a new
one. If a combination meter assembly which was installed to another
vehicle is used, the information stored in it will not match the
information from the vehicle and a DTC may be stored. PROCEDURE 1. INSPECT STEERING PAD SWITCH ASSEMBLY (a) Remove the steering pad switch assembly.
