Any of the following lights remain on: (ABS warning light, BRAKE system warning light, DSC indicator light and/or DSC OFF light)

[TROUBLESHOOTING HINTS] •  Brake fluid amount is low. •  Parking brake is not released. •  No connection at DSC CM connector (When DSC CM connector goes out, ABS warning light and BRAKE system warning light illuminate.) •  DSC CM detected malfunction (input and output device malfunction). •  DSC CM detects low voltage in power supply circuit. •  DSC CM GND malfunction (When DSC CM GND is not securely connected, ABS warning light and BRAKE system warning light illuminate but no DTC is displayed.) •  DSC CM does not operate (DSC CM malfunction).

Diagnostic procedure

STEP	INSPECTION		ACTION
1	INSPECT BRAKE FLUID AMOUNT AND VERIFY THAT PARKING BRAKE RELEASES •  Is the brake fluid amount normal? •  Is the parking brake lever released?	Yes	Go to the next step.
		No	Add brake fluid or release the parking brake lever.
2	INSPECT FOR DTCS IN DSC •  Retrieve DSC DTC using the M-MDS. •  Is there any DSC DTC displayed?	Yes	Go to applicable DTC troubleshooting procedure. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
		No	Go to the next step.
3	INSPECT DTCS IN INSTRUMENT CLUSTER •  Retrieve instrument cluster DTC using the M-MDS. •  Is DTC U0415:92 displayed?	Yes	Go to the next step.
		No	Go to Step 6.
4*	INSPECT DSC CM POWER SUPPLY VOLTAGE •  Monitor PID VPWR using the M-MDS data monitor function. •  Is the monitoring value above 10 V?	Yes	DSC CM internal malfunctions. Replace the DSC CM. (See DSC HU/CM REMOVAL/INSTALLATION [L.H.D.].) (See DSC HU/CM REMOVAL/INSTALLATION [R.H.D.].)
		No	Go to the next step.
5	INSPECT WHETHER MALFUNCTION IS IN INSTRUMENT CLUSTER OR ELSEWHERE •  Release the parking brake. •  Turn off all warning light and indicator light using M-MDS simulation function WL+IL? (See ACTIVE COMMAND MODES TABLE [INSTRUMENT CLUSTER].) •  Does the DSC warning light turn off?	Yes	Go to the next step.
		No	Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
6	INSPECT FOR CONNECTION OF DSC HU/CM CONNECTOR •  Is the DSC HU/CM connector connected securely?	Yes	Go to Step 8.
		No	Connect the connector securely, then go to the next step.
7	VERIFY DSC WARNING LIGHT OPERATION •  Turn the ignition switch to ON position. •  Does the DSC warning light turn off 4 seconds after the ignition switch is ON position?	Yes	Troubleshooting is completed. (DSC HU/CM connector is not connected securely.)
		No	Go to the next step.
8	INSPECT BATTERY VOLTAGE •  Inspect battery voltage. •  Is the battery voltage normal?	Yes	Go to the next step.
		No	Inspect charging system. Replace the battery if necessary.
9	INSPECT BATTERY VOLTAGE WHILE ELECTRICAL LOAD IS OPERATING •  Inspect the battery voltage while electrical load (A/C, headlight etc.) is operating. •  Is the battery voltage normal?	Yes	Inspect wiring harness in DSC HU/CM terminal Y and terminal B related circuit.
		No	Go to the next step.
10	INSPECT CHARGING SYSTEM •  Inspect the battery voltage normal with electrical load (such as, A/C headlight) on the engine idling?	Yes	Go to the next step.
		No	Inspect the charging system (such as drive belt tension, generator). (See GENERATOR INSPECTION [ZJ, ZY].) (See GENERATOR INSPECTION [MZ-CD 1.6 (Y6)].)
11	INSPECT FOR SHORT TO GND CIRCUIT IN WIRING BETWEEN BCM AND BRAKE SYSTEM WARNING LIGHT RELATED SWITCHES •  Inspect for open circuit in wiring for following: ―  Between parking switch and BCM terminal 7B ―  Between brake fluid level sensor and BCM terminal 4A •  Is the short to GND circuit detected?	Yes	Repair or replace malfunctioning part.
		No	Replace the BCM. (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION.)
