Mazda CX-5 Service & Repair Manual: 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.
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.
