ESC OPERATION MODE
1. STEP 1
The ESC analyzes the intention of the driver.

Step 1:

2. STEP 2
It analyzes the movement of the ESC vehicle.

Step 2:

3. STEP 3
The HECU calculates the required strategy, then actuates the appropriate valves and sends torque control requests via CAN to maintain vehicle stability.

ABS WARNING LAMP MODULE
The active ABS warning lamp module indicates the self test and failure status of the ABS The ABS warning lamp shall be on:
- During the initialization phase after IGN ON. (continuously 3 seconds).
- In the event of inhibition of ABS functions by failure.
- During diagnostic mode.
- When the ECU Connector is separated from ECU.

EBD/PARKING BRAKE WARNING LAMP MODULE
The active EBD warning lamp module indicates the self test and failure status of the EBD. However, in case the Parking Brake Switch is turned on, the EBD warning lamp is always turned on regardless of EBD functions. The EBD warning lamp shall be on:
- During the initialization phase after IGN ON. (continuously 3 seconds).
- When the Parking Brake Switch is ON or brake fluid level is low.
- When the EBD function is out of order.
- During diagnostic mode.
- When the ECU Connector is separated from ECU.

ESC WARNING LAMP (ESC SYSTEM)
The ESC warning lamp indicates the self-test and failure status of the ESC.
The ESC warning lamp is turned on under the following conditions:
- During the initialization phase after IGN ON. (continuously 3 seconds).
- In the event of inhibition of ESC functions by failure.
- When driver turn off the ESC function by on/off switch.
- During diagnostic mode.

ESC FUNCTION LAMP (ESC SYSTEM)
The ESC function lamp indicates the self-test and operating status of the ESC.
The ESC Function lamp operates under the following conditions:
- During the initialization phase after IGN ON. (continuously 3 seconds).
- When the ESC control is operating. (Blinking - 2Hz)

ESC ON/OFF SWITCH (ESC SYSTEM)
The ESC On/Off Switch shall be used to toggle the ESC function between On/Off states based upon driver input. The On/Off switch shall be a. normally open, momentary contact switch.
Initial status of the ESC function is on and the switch is used to request an ESC status change.
