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 DTC Table.)
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.
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).
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.
No
Connect the DSC HU/CM connector terminal or related connector terminals securely.
