What causes the VDC light to illuminate in an old Teana?
1 Answers
VDC, similar to ESP, is a vehicle stability control system. The illumination of the VDC OFF light indicates that the vehicle stability control system is in a deactivated state. When the stability system is active, the indicator light remains off. If the VDC OFF light suddenly illuminates, it signifies that the stability system is intervening in the vehicle's operation. However, if the indicator light stays constantly lit, it may indicate that the stability system has been manually deactivated or is experiencing a malfunction. Normally, the VDC indicator light remains off and only illuminates when the system detects wheel slip and intervenes to stabilize the vehicle, extinguishing automatically once the intervention is complete. Here are important considerations: 1. Upon initial vehicle startup, certain warning lights may briefly illuminate as part of the system self-check. These should extinguish after the ECU verifies proper operation through sensor data. Persistent illumination of any warning light indicates a system fault requiring prompt diagnosis at an authorized service center. 2. When the instrument panel displays "STOP," the driver must immediately cease operation as this indicates a critical vehicle malfunction. Continued driving under such conditions may cause severe damage to the vehicle.
