9
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 HU/CM connector
(When DSC HU/CM connector goes out, ABS warning light and BRAKE system warning light illuminate.)
•  DSC HU/CM detected malfunction (input and output device malfunction).
•  DSC HU/CM detects low voltage in power supply circuit.
•  DSC HU/CM ground malfunction
(When DSC HU/CM ground is not securely connected, ABS warning light and BRAKE system warning light illuminate but no DTC is displayed.)
•  DSC HU/CM does not operate (DSC HU/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 HU/CM
•  Have DTCs been stored in memory?
Yes
Perform the applicable DTC inspection.
(See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
No
Go to the next step.
3
INSPECT IF MALFUNCTION IS IN CONTROL MODULE CONNECTOR, TERMINAL OR OTHER
•  Do ABS warning light and BRAKE system warning light go out after 4 s with the ignition switch turned to the ON position?
Yes
Temporary poor connection in control module connector.
Inspect the DSC HU/CM connector, then go to Step 6.
Inspect the DSC HU/CM connector terminal, then go to Step 7.
No
Go to the next step.
4
INSPECT BATTERY
•  Is the battery voltage normal?
Yes
Go to the next step.
No
Inspect the battery and charging system.
(See BATTERY INSPECTION [ZJ, ZY, Z6].)
(See BATTERY INSPECTION [LF, L3].)
(See BATTERY INSPECTION [L3 Turbo].)
(See BATTERY INSPECTION [MZ-CD 1.6 (Y6)].)
(See GENERATOR INSPECTION [ZJ, ZY, Z6].)
(See GENERATOR INSPECTION [LF, L3].)
(See GENERATOR INSPECTION [L3 Turbo].)
(See GENERATOR INSPECTION [MZ-CD 1.6 (Y6)].)
5
INSPECT CHARGING SYSTEM
•  Is the battery voltage normal with electrical load (such as A/C, headlight) on and engine idling?
Yes
Go to the next step.
No
Inspect the charging system (such as drive belt tension, generator).
(See GENERATOR INSPECTION [ZJ, ZY, Z6].)
(See GENERATOR INSPECTION [LF, L3].)
(See GENERATOR INSPECTION [L3 Turbo].)
(See GENERATOR INSPECTION [MZ-CD 1.6 (Y6)].)
6
VERIFY THAT DSC HU/CM CONNECTOR IS CONNECTED
•  Is the DSC HU/CM securely connected?
Yes
Go to the next step.
No
Connect the DSC HU/CM connector securely, then go to the next step.
7
VERIFY THAT DSC HU/CM CONNECTOR TERMINAL OR RELATED CONNECTOR TERMINALS ARE CONNECTED
•  Are DSC HU/CM connector terminal or instrument cluster connector terminal, related connector terminals securely connected?
Yes
Replace the DSC CM.
(See DSC HU/CM REMOVAL/INSTALLATION.)
No
Connect the DSC HU/CM connector terminal or related connector terminals securely.
