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 does not release
• Improper brake switch signal input to PCM (the brake system warning light (vehicle without the malfunction warning light) / malfunction warning light (vehicle equipped with the malfunction warning light) illuminate)*
• No connection at DSC HU/CM connector
(When DSC HU/CM connector is disconnected, 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
• DSC HU/CM ground malfunction
(When DSC HU/CM ground is not securely connected, ABS warning light and BRAKE system warning light illuminate but diagnostic trouble code does not 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?

|
Yes
|
Go to the next step.
|
No
|
Add brake fluid or release parking brake lever.

2
|
INSPECT PCM DTC
• Perform the PCM ON-BOARD DIAGNOSTIC procedure.
• Is the DTC P0571 and/or P0703 present?
|
Yes
|
Go to the appropriate DTC inspection.
(See DTC P0571 [13B-MSP].)
(See DTC P0703 [13B-MSP].)
|
No
|
Go to the next step.
|

3
|
INSPECT DTCS IN DSC HU/CM
• Inspect the DTC for the DSC ON-BOARD DIAGNOSTIC SYSTEM.
• Have DTCs been stored in memory?
|
Yes
|
Perform inspection using appropriate DTC.
|
No
|
Go to the next step.
|
||
4
|
INSPECT WHETHER MALFUNCTION IS IN CONTROL MODULE CONNECTOR, TERMINAL OR OTHER
• Do ABS warning light and BRAKE system warning light go off after 4 s when the ignition switch is turned to the ON position?
|
Yes
|
Temporary poor connection in control module connector.
Inspect DSC HU/CM connector, then go to Step 7.
Inspect DSC HU/CM connector terminal, then go to Step 8.
|
No
|
Go to the next step.
|
||
5
|
INSPECT BATTERY
• Is the battery voltage normal?
|
Yes
|
Go to the next step.
|
No
|
Inspect the battery and charging system.
(See BATTERY INSPECTION [13B-MSP].)
|
||
6
|
INSPECT CHARGING SYSTEM
• Is the battery voltage normal with electrical load (A/C, headlight, etc.) on and engine idling?
|
Yes
|
Go to the next step.
|
No
|
Inspect the charging system (drive belt tension, generator, etc.).
|
||
7
|
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.
|
||
8
|
VERIFY THAT DSC HU/CM CONNECTOR TERMINAL OR RELATED CONNECTOR TERMINALS ARE CONNECTED
• Are DSC HU/CM connector terminal or instrument cluster connector terminal etc. related connector terminals securely connected?
|
Yes
|
Replace the DSC HU/CM.
|
No
|
Securely connect the DSC HU/CM connector terminal and related connector terminals.
