DTC Code DTC Name
C15B1/71 ECU Malfunction(CPU)
C15B2/72 ECU Malfunction(Internal Line)
C15B3/73 ECU Malfunction(Substrate Temperature Sensor)
C15B5/82 ECU Malfunction(Flash Memory)
C15B6/83 ECU Malfunction(EEPROM)

DESCRIPTION

If the VGRS ECU (steering control ECU) detects an internal malfunction, it turns the master warning light on, and stores these DTCs.

When DTC C15B3/73 is stored, the master warning light is not illuminated and the VGRS system continues to operate.
