Power Steering Malfunction Indicator Light/power Steering Malfunction Indication

Purpose

•  The power steering malfunction indicator light/indication warns the driver that there is a malfunction with the Electric Power Steering (EPS) system.

Function

•  The instrument cluster turns on the electric power steering warning light/electric power steering indication based on the system malfunction indication request signal sent from the EPS control module (CM) via CAN communication. For details on the illumination conditions, refer to [EPS CM] item. (See ELECTRIC POWER STEERING (EPS) CONTROL MODULE.)

Note

•  If the electric power steering warning light/electric power steering indication turns on, the steering assist power may weaken.

•  If the EPS system and CAN lines are normal, it illuminates when the main power is switched ON (READY off), and turns off after the main power is switched ON (READY on). If there is a system malfunction, the power steering malfunction indicator light illuminates.

•  A warning message in the center display is displayed with the power steering malfunction indicator light turned on or flashed. For the message content and verification method, refer to the [CENTER DISPLAY] in the workshop manual.

Construction

•  The power steering malfunction indicator light is built into the instrument cluster.

•  The electric power steering warning indication is displayed on the multi-information display.
