Symptom Troubleshooting [Electronically Controlled Brake System]

Verify the malfunctioning symptom and perform the applicable numbered malfunction diagnosis.

SYMPTOM TROUBLESHOOTING (ELECTRONICALLY CONTROLLED BRAKE SYSTEM)

No.

Description

Refer to

Any of the following lights do not illuminate with the ignition ON/main power ON: (ABS warning light, brake system warning light, TCS/DSC indicator light and/or TCS OFF indicator light)

(See ANY OF THE FOLLOWING LIGHTS DO NOT ILLUMINATE WITH THE IGNITION ON/MAIN POWER ON: (ABS WARNING LIGHT, BRAKE SYSTEM WARNING LIGHT, TCS/DSC INDICATOR LIGHT AND/OR TCS OFF INDICATOR LIGHT) [ELECTRONICALLY CONTROLLED BRAKE SYSTEM] ).

Any of the following lights stay on: (ABS warning light, TCS/DSC indicator light and/or TCS OFF indicator light)

(See ANY OF THE FOLLOWING LIGHTS STAY ON: (ABS WARNING LIGHT, TCS/DSC INDICATOR LIGHT AND/OR TCS OFF INDICATOR LIGHT) [ELECTRONICALLY CONTROLLED BRAKE SYSTEM] ).

Brake system warning light stay on

(See 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 TCS OFF indicator light/off-road traction assist indicator light do not illuminate

(See THERE IS A MALFUNCTION IN THE SYSTEM EVEN THOUGH ABS WARNING LIGHT, BRAKE SYSTEM WARNING LIGHT, TCS/DSC INDICATOR LIGHT AND TCS OFF INDICATOR LIGHT/OFF-ROAD TRACTION ASSIST INDICATOR LIGHT DO NOT ILLUMINATE [ELECTRONICALLY CONTROLLED BRAKE SYSTEM] ).

ABS or TCS ⁽¹⁾ operates frequently

(See ABS OR TCS OPERATES FREQUENTLY/TCS DOES NOT WORK CORRECTLY [ELECTRONICALLY CONTROLLED BRAKE SYSTEM] ).

TCS ⁽¹⁾ does not work correctly

DSC ⁽²⁾ operates frequently

(See DSC OPERATES FREQUENTLY/DSC DOES NOT WORK CORRECTLY [ELECTRONICALLY CONTROLLED BRAKE SYSTEM] ).

DSC ⁽²⁾ does not work correctly

Hill Launch Assist (HLA) operates even on a downhill

(See HILL LAUNCH ASSIST (HLA) OPERATES EVEN ON A DOWNHILL/HILL LAUNCH ASSIST (HLA) DOES NOT OPERATE ON A SLOPE [ELECTRONICALLY CONTROLLED BRAKE SYSTEM] ).

Hill Launch Assist (HLA) does not operate on a slope

AUTOHOLD does not work

(See AUTOHOLD DOES NOT WORK [ELECTRONICALLY CONTROLLED BRAKE SYSTEM] ).

Brake pedal-to-floor clearance is lower than standard (no brake fluid leakage and trapped air)

(See BRAKE PEDAL-TO-FLOOR CLEARANCE IS LOWER THAN STANDARD (NO BRAKE FLUID LEAKAGE AND TRAPPED AIR) [ELECTRONICALLY CONTROLLED BRAKE SYSTEM] ).

⁽¹⁾	The DSC system also includes the TCS function, and the TCS/DSC operation indicator light flashes during TCS operation.

⁽²⁾	The TCS/DSC operation indicator light flashes during DSC operation.
