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
