3	There is a malfunction in the system even though ABS warning light, brake system warning light, DSC indicator light and DSC OFF light do not illuminate
Possible cause	• There is a mechanical malfunction in system ― DSC HU/CM DTC is stored ― Conventional brake system malfunction ― Improper operation of solenoid valve

Diagnostic procedure

STEP	INSPECTION		ACTION
1	CONFIRM DSC HU/CM DTC • Retrieve the DSC HU/CM DTC using the M-MDS. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
1		No	Go to the next step.
2	VERIFY SOLENOID VALVE OPERATION • Switch the ignition to off. • Connect the M-MDS to the DLC-2. • Switch the ignition to ON (engine off). • Access the active command mode for the solenoid valve using the M-MDS. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) • Does the solenoid valve operate properly?	Yes	Inspect the conventional brake system. Repair or replace if necessary.
2		No	Repair or replace the malfunctioning part.
