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.

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.

Initial check

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 a system malfunction, the power steering malfunction indicator light illuminates.
