Traction Control Indicator Lamp: Description and Operation

Traction Control System (TCS) function lamp
- When the ignition is placed in the drive position, the function lamp lights for 3 seconds.
- In the case of wheelspin that requires a reduction of more than 7% in the engine torque, the function lamp lights after a short delay (360ms). However, in the case of torque reduction greater than 30% the lamp lights without delay. The function lamp is then lit as long as the system is working, up to a maximum of 1 second.
- The function lamp is lit by the control module grounding pin 12.





Warning Lamp TCS OFF
- When the ignition is placed in the drive position, the warning lamp lights for 3 seconds.
- In the case of a fault in the system, the warning lamp stays lit and is lit by the control module grounding the lamp circuit in pin 26.
- The warning lamp is also lit when the system is manually disengaged, which can be done at speeds under 60 km/h by pressing in the TCS switch. The system can be engaged at any speed by pressing the TCS button, at which point the TCS OFF lamp goes out.
- At ignition ON when starting, the system is always engaged automatically.
