POWER STEERING MALFUNCTION INDICATOR LIGHT/POWER STEERING MALFUNCTION INDICATION
POWER STEERING MALFUNCTION INDICATOR LIGHT/POWER STEERING MALFUNCTION INDICATION
SM2334130
id061300250100
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 [(US)].)
-
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 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.• 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.

Operation
Power steering malfunction indicator light
1. The instrument cluster receives (1) the system malfunction indication request signal from the EPS CM.
2. The instrument cluster turns the transistor on (2) based on the system malfunction indication request signal.
3. When the transistor turns on, the electric power steering warning light turns on (3).
