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
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.
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.

Ion Sensor
Purpose/Function
Detects ion generation in the combustion chamber for detecting pre-ignition.
Detects ions which occur due to fuel combustion as current by applying bias
voltage to the spark plug, which is amplified in the ignition coil internal
circuit and input to the PCM.
