POWER STEERING MALFUNCTION INDICATOR LIGHT

Purpose

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

Function

  • If there is a malfunction in the EPS system, the power steering malfunction indicator light illuminates.

  • If the EPS system and CAN lines are normal, it illuminates when the ignition is switched ON (engine off), and turns off after the engine is started.

  • If there is an internal circuit malfunction in the resolver sensor, the power steering malfunction indicator light illuminates to warn the driver that EPS assist force is weakening. (See ELECTRIC POWER STEERING (EPS) CONTROL MODULE.)

Construction

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

Operation

EPS system malfunction detection
  • If the EPS Control Module (CM) detects a system malfunction, it sends a power steering malfunction indicator light illumination on request signal to the instrument cluster via CAN.

  • The instrument cluster illuminates the power steering malfunction indicator light when it receives a power steering malfunction indicator light illumination on request signal.

NOTE:

  • When the power steering malfunction indicator light turns on, a warning message is displayed in the center display. For the message content and verification method, refer to the [CENTER DISPLAY (WITH CENTER DISPLAY)] IN BODY & ELECTRICAL (09 SECTION). (With center display) (See CENTER DISPLAY [WITH CENTER DISPLAY].)

Initial check
