(See NO. 1 ANY OF THE FOLLOWING LIGHTS DO NOT ILLUMINATE WITH THE IGNITION ON: (ABS WARNING LIGHT, BRAKE SYSTEM WARNING LIGHT, TCS/DSC INDICATOR LIGHT AND/OR DSC OFF INDICATOR LIGHT) [ELECTRONICALLY CONTROLLED BRAKE SYSTEM] .)

Any of the following lights stay on:

ABS warning light
TCS/DSC indicator light
DSC OFF indicator light

(See NO. 2 ANY OF THE FOLLOWING LIGHTS STAY ON: (ABS WARNING LIGHT, TCS/DSC INDICATOR LIGHT AND/OR DSC OFF INDICATOR LIGHT) [ELECTRONICALLY CONTROLLED BRAKE SYSTEM] .)

Brake system warning light stay on

(See NO. 3 BRAKE SYSTEM WARNING LIGHT STAY ON [ELECTRONICALLY CONTROLLED BRAKE SYSTEM] .)

There is a malfunction in the system even though ABS warning light, brake system warning light, TCS/DSC indicator light and DSC OFF indicator light do not illuminate

(See NO. 4 THERE IS A MALFUNCTION IN THE SYSTEM EVEN THOUGH ABS WARNING LIGHT, BRAKE SYSTEM WARNING LIGHT, TCS/DSC INDICATOR LIGHT AND DSC OFF INDICATOR LIGHT DO NOT ILLUMINATE [ELECTRONICALLY CONTROLLED BRAKE SYSTEM] .)

ABS or TCS ⁽¹⁾ operates frequently

(See NO. 5 ABS OR TCS ⁽¹⁾ OPERATES FREQUENTLY/TCS DOES NOT WORK CORRECTLY ⁽¹⁾: DSC SYSTEM FUNCTION CONTAINS TRACTION CONTROL FUNCTION, TCS/DSC INDICATOR LIGHT GOES ON AND OFF WHILE TCS OPERATES [ELECTRONICALLY CONTROLLED BRAKE SYSTEM].)

TCS ⁽¹⁾ does not work correctly

DSC ⁽²⁾ operates frequently

(See NO. 6 DSC ⁽²⁾ OPERATES FREQUENTLY/DSC DOES NOT WORK CORRECTLY ⁽²⁾: TCS/DSC INDICATOR LIGHT GOES ON AND OFF WHILE DSC OPERATES [ELECTRONICALLY CONTROLLED BRAKE SYSTEM].)
