Description of functions
The combination meter ASSY receives vehicle speed signals from the brake actuator ASSY via CAN communication. The combination meter ASSY displays the vehicle speed based on the received vehicle speed signals.
NOTE:
Even when the speed meter is normal, slight difference may be present between the reading value and the actual vehicle speed. There are two possible causes for this difference. One is an external cause resulting from the tire size, tire pressure, and tire wear. The other is an internal factor resulting from the allowable range of the reading. Therefore, before troubleshooting, you must first check if these causes are related to the error. The tire size, pressure, and wear (external causes) are checked visually. (Refer to
FRONT WHEEL ALIGNMENT
) The allowable range of reading (internal cause) is checked using a speed meter tester. (Refer to
METER & GAUGE SYSTEM )
