- SYMPTOM TROUBLESHOOTING [DYNAMIC STABILITY CONTROL (DSC)]
- Verify the symptoms, and perform troubleshooting according to the appropriate number.
No. Symptom 1 Any of the following lights are not illuminated when the ignition is switched ON: - ABS warning light
- Brake warning light
- Slip indicator light
- DSC OFF indicator light
2 Any of the following lights remain illuminated: - ABS warning light
- Slip indicator light
- DSC OFF indicator light
3 Brake warning light remains illuminated 4 A malfunction in the system even though the ABS warning light, brake warning light, slip indicator light and DSC OFF indicator light are not illuminated 5 ABS or TCS*1 operates frequently
*1: DSC system function contains traction control function, slip indicator light turns on and off while TCS operatesTCS does not work correctly 6 DSC*2 operates frequently
*2: Slip indicator light turns on and off while DSC operatesDSC does not work correctly 7 Hill start assist operates even on a down slope Hill start assist does not operate on a slope 8 Smart city brake support (SCBS) warning light (amber) turns on and message indicating smart city brake support (SCBS) malfunction is displayed in center display Troubleshooting item 1 2 3 4 5 6 7 8 Any of the following lights are not illuminated with the ignition switched ON: (ABS warning light, brake warning light, slip indicator light and/or DSC OFF indicator light) Any of the following lights remain illuminated: (ABS warning light, slip indicator light and/or DSC OFF indicator light) brake warning light remains illuminated A malfunction in the system even though the ABS warning light, brake warning light, slip indicator light and DSC OFF indicator light are not illuminated ABS or TCS*1 operates frequently TCS does not work correctly
