ACTIVE TEST
CAUTION:
• Do not perform active test while driving vehicle.
• Make sure to completely bleed air from brake system.
• The active test cannot be performed with the AB S warning lamp, VDC indicator lamp, SLIP indicator
lamp or brake warning lamp on.
• ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp are on
during active test.
NOTE:
• When active test is performed while depressing the pedal, the pedal depression amount will change. This is
normal. (Only solenoid valve and ABS motor)
• “TEST IS STOPPED” is displayed 10 seconds after operation start.
• After “TEST IS STOPPED” is displayed, to perform test again, touch BACK.
Test Item
SOLENOID VALVE• When performing an active test of the ABS function, select “MAIN SIGNALS” for each test item.
• For ABS solenoid valve, touch “Up”, “Keep”, and “Dow n” on the display screen. For ABS solenoid valve
(ACT), touch “Up”, “ACT UP ”, “ACT KEEP” and confirm that solenoid valves operate as shown in the table
below.

Service Notice or PrecautionINFOID:0000000005928990
•Use recommended brake fluid when adding fluid to the clutch reservoir tank. Refer to MA-14.
• Never reuse fluid drained from clutch system.
• Be careful not to splash brake fluid on painted areas.
• Use new brake fluid to clean or wash all part s of master cylinder and operating cylinder.
• Never use mineral oils such as gasoline or kerosene. It will ruin the rubber parts of the hydraulic sys-
tem.
• If transaxle assembly is removed from the vehicle, always replace CSC (Con centric slave cylinder).
Return CSC to original position to remove transaxle assembly. Dust on clutch disc sliding parts may
damage CSC seal and may cause clutch fluid leakage.
• Do not disassemble clutch master cylinder and CSC.
WARNING:
After cleaning clutch disc, cl ean it with a dust collector. Do not use compressed air.

• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.
