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 seperated from ECU.
-
Cluster lamp is ON when communication is impossible with CAN module.
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 shallbe 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 seperated from ECU.
-
Cluster lamp is ON when communication is impossible with CAN module.
ESC Function/Warning Lamp
The ESC function/warning lamp indicates the self-test and failure status of the ESC.
The ESC function/warning lamp is turned on under the following conditions :
-
During the initialization phase after IGN ON. (continuously 3 seconds).
-
When the ESC function is inhibited by system failure.
-
When the ESC control is operating. (Blinking - 2Hz)
-
During diagnostic mode.(Except standard mode)
-
Cluster lamp is ON when communication is impossible with CAN module.
ESC Off Lamp
The ESC Off lamp indicates the self-test and operating status of the ESC.
The ESC Off lamp operates under the following conditions :
-
During the initialization mode after IGN ON. (continuously 3 seconds).
-
ESC Off lamp is On when driver input the ESC Off switch.
ESC On/Off Switch
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.Closed contacts switch the circuit to ignition.
Initial status of the ESC function is on and switch toggle the state.
