VARIABLE GEAR RATIO STEERING SYSTEM, Diagnostic DTC:C15B1/71, C15B2/72, C15B3/73, C15B5/82, C15B6/83

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 (front 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.

DTC No. Detection Item DTC Detection Condition Trouble Area Warning Indicate Return-to-normal Condition
C15B1/71 ECU Malfunction(CPU) When the engine switch is turned on (IG), the VGRS ECU (front steering control ECU) detects an internal malfunction. VGRS ECU (front steering control ECU) Comes on Engine switch on (IG) again
C15B2/72 ECU Malfunction(Internal Line) When the engine switch is turned on (IG), the VGRS ECU (front steering control ECU) detects an internal malfunction. VGRS ECU (front steering control ECU) Comes on Engine switch on (IG) again
C15B3/73 ECU Malfunction(Substrate Temperature Sensor) When the engine switch is turned on (IG), the VGRS ECU (front steering control ECU) detects an internal malfunction. VGRS ECU (front steering control ECU) Does not come on Engine switch on (IG) again
C15B5/82 ECU Malfunction(Flash Memory) When the engine switch is turned on (IG), the VGRS ECU (front steering control ECU) detects an internal malfunction. VGRS ECU (front steering control ECU) Comes on Engine switch on (IG) again
C15B6/83 ECU Malfunction(EEPROM) When the engine switch is turned on (IG), the VGRS ECU (front steering control ECU) detects an internal malfunction. VGRS ECU (front steering control ECU) Comes on Engine switch on (IG) again

CAUTION / NOTICE / HINT
