BRAKE FLUID
On-Board InspectionINFOID:0000000001327610
LEVEL CHECK
Make sure the fluid level in reservoir tank is within the standard(between MAX and MIN lines).
Visually check around reservoir tank for fluid leakage.
If fluid level is excessively low, check brake system for leakage.
Release parking brake pedal and see if brake warning lamp goes off. If not, check brake system for fluid leakage.
Drain and RefillINFOID:0000000001327611
CAUTION:
Refill with new brake fluid “DOT3”.
Do not reuse drained brake fluid.
Be careful not to splash brake fluid on painted areas; it way cause paint damage. If brake fluid is
splashed on painted surfaces of bo dy, immediately wipe it off and them wash it away with water
immediately.
Before working, disconnect connectors of ABS actua tor and electric unit (control unit) or battery
negative terminal.
1. Connect a vinyl tube to each bleed valve.
2. Depress brake pedal, loosen each bleed valve, and gradually remove brake fluid.
3. Make sure there is no foreign material in reservoir tank, and refill with new brake fluid.
4. Rest foot on brake pedal. Loosen bleed valve. Slowly depress pedal until it stops. Tighten bl eed valve. Release brake pedal.
Repeat this process a few times, then pause to add new brake
fluid to master cylinder. Continue until new brake fluid flows out.
5. Bleed Air. Refer to BR-8, "
Bleeding Brake System".

Carefully monitor brake fluid level in reservoir tank during bleeding operation.
Refill with new brake fluid “DOT 3”. Make sure it is at least half
way at all times while bleeding air out of system.
Place a container under master cylinder not to spill brake fluid.
Turn ignition switch OFF and disconnect ABS actuator and
electric unit (control unit) or battery negative terminal.
Bleed air in the following order. Right rear brake → Left front
brake → Left rear brake → Right front brake
1. Connect a transparent vinyl tube to bleed valve.
2. Fully depress brake pedal several times.
3. With brake pedal depressed, open bleed valve to release air.
4. Close bleed valve.
5. Release brake pedal slowly.
6. Repeat steps 2, through 5, until clear brake fluid comes out of bleed valve.

TROUBLE DIAGNOSIS
Basic Inspection
INFOID:0000000001327676
BRAKE FLUID AMOUNT, LEAKS, AND BRAKE PADS INSPECTION
1. Check fluid level in the brake reservoir tank. If fluid level is low, refill brake fluid.
2. Check brake piping and around ABS actuator and electric uni t (control unit) for leaks. If there is leaking or
oozing fluid, check the following items.
If ABS actuator and electric unit (control unit) connec tion is loose, tighten piping to the specified torque
and re-perform the leak inspection to make sure there are no leaks.
If there is damage to the connection flare nut or AB S actuator and electric unit (control unit) screw,
replace the damaged part and re-perform the leak inspection to make sure there are no leaks.
When there is fluid leaking or oozing from a part other than ABS actuator and electric unit (control unit)
connection, if fluid is just oozing out, use a clean cl oth to wipe off the oozing fluid and re-check for leaks.
If fluid is still oozing out, replace the damaged part.
When there is fluid leaking or oozing at ABS actuator and electric unit (control unit), if fluid is just oozing
out, use a clean cloth to wipe off oozing fluid and re-che ck for leaks. If fluid is still oozing out, replace
ABS actuator and electric unit (control unit) body.
CAUTION:
ABS actuator and electric unit (contr ol unit) body can not be disassembled.
3. Check brake pad degree of wear. Refer to BR-18, "
On-Vehicle Inspection" in “Front Disc Brake” and BR-
24, "On-Vehicle Inspection" in “Rear Disc Brake”
POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION
Make sure battery positive cable, negative cabl e and ground connection are not loose. If looseness is
detected, tighten the cables. In additi on, check the battery voltage to make sure it has not dropped and alter-
nator is normal.
ABS WARNING LAMP, VDC OFF INDICATOR LAMP, SLIP INDICATOR LAMP AND BRAKE WARN-
ING LAMP INSPECTION
Symptom Symptom description Result
Motor operation noise This is noise of motor in
side ABS actuator and electr ic unit (control unit).
Slight noise may occur during VDC, TCS, and ABS operation.
Normal
When the vehicle speed goes over 20 km/h (12.5 MPH), motor and valves
operating noise may be heard. It happens only once after ignition switch is
ON. This is a normal status of the system operation check.
System operation check noise When engine starts, slight “click” noise may be heard from engine room.
This is normal and is part of system operation check. Normal
VDC/TCS operation
(SLIP indicator lamp blinking) TCS may activate momentarily if wheel speed changes when driving over
location where friction coefficient varies, when up/downshifting, or when ful-
ly depressing accelerator pedal.
Normal
Cancel the VDC/TCS
function for the inspec-
tion on a chassis dyna-
mometer.
For inspection of speedometer or other instruments, press VDC OFF switch
to turn VDC/TCS function off.
When accelerator pedal is depressed on a chassis dynamometer (fixed
front-wheel type), vehicle speed will not increase. This is not normal. It is re-
sult of TCS being activated by stationary front wheels. Warning lamp may
also illuminate to indicate “sensor system error”. This is also normal, and is
the result of the stationary front wheels being detected. To be certain, restart
engine, and drive vehicle at 30 km/h (19 MPH) or more. Make sure warning
lamp does not illuminate.
ABS operation
(Longer stopping distance) On roads with low friction coefficients, such as snowy roads or gravel roads,
vehicles with ABS may require a longer stopping distance. Therefore, when
driving on such roads, avoid overconfidence and keep speed sufficiently
low.
Normal
Insufficient feeling of accelera-
tion Depending on road conditions, driver may feel that feeling of acceleration is
insufficient. This is because traction control, which controls engine and
brakes to achieve optimal traction, has the highest priority (for safety). As a
result, there may be times when acceleration is slightly less than usual for
the same accelerator pedal operation.
Normal
