ABS Warning Lamp Module. The active ABS warning lamp module indicates the self-check and failure status of the ABS. The ABS warning lamp should illuminate:

• During the initialization phase after IGN ON (constantly for 3 seconds).
• In case of ABS operation failure during braking.
• In diagnostic mode.
• When the ECU connector is disconnected from the ECU.
• The cluster lamp illuminates when communication with the CAN module is not possible.

EBD/Parking Brake Warning Lamp Module. The active EBD warning lamp module indicates the self-check and failure status of the EBD. However, if the parking brake switch is on, the EBD warning lamp always illuminates regardless of EBD function. The EBD warning lamp should illuminate:

• During the initialization phase after IGN ON (constantly for 3 seconds).
• When the parking brake switch is on or the brake fluid level is low.
• When the EBD function has failed.
• In diagnostic mode.
• When the ECU connector is disconnected from the ECU.
• The cluster lamp illuminates when communication with the CAN module is not possible.

ESC Function / Warning Lamp. The ESC function/warning lamp indicates the ESC self-check and malfunction status. The ESC function/warning lamp illuminates under the following conditions:

• During the initialization phase after IGN ON (constantly for 3 seconds).
• When the ESC function is inhibited due to a system failure.
• When ESC control is operating. (Flashing - 2 Hz)
• In diagnostic mode (other than standard mode).
• The cluster lamp illuminates when communication with the CAN module is not possible.

ESC Off Lamp: The ESC OFF lamp indicates the ESC self-check and operating status. The ESC OFF lamp operates under the following conditions:

• In initialization mode after IGN ON (continuously for 3 seconds).
• The ESC OFF lamp illuminates when the driver presses the ESC OFF button.

ESC On/Off Switch. The ESC On/Off switch is used to toggle the ESC function between on and off states depending on driver operation. The On/Off switch must be a normally open, momentary contact switch. When the contacts are closed, the switch connects the circuit to the ignition. The initial state of the ESC function is on, and the switch toggles the state.
