Inspections Before Trouble DiagnosisNCS001BH
A/T CHECK
A/T Fluid Leakage and A/T Fluid Level Check
Check for A/T fluid leakage and check the A/T fluid level. Refer to AT- 1 3 , "Checking A/T Fluid" .
A/T Fluid Condition Check
Inspect the A/T fluid condition.
STALL TEST
Stall Test Procedure
1. Inspect the amount of engine oil. Replenish the engine oil if necessary.
2. Drive for about 10 minutes to warm up the vehicle so that the A/ T fluid temperature is 50 to 80 °C (122 to 176 °F). Check the
amount of ATF. Replenish if necessary.
3. Securely engage the parking brake so that the tires do not turn.
4. Start engine, apply foot brake, and place selector lever in “D” position.
5. While holding down the foot brake, gradually press down the accelerator pedal.
6. Quickly read off the stall speed, then quickly remove your foot from the accelerator pedal.
CAUTION:
Do not hold down the accelerator pedal for more than 5 sec-
onds during this test.
7. Move the selector lever to the “N” position.

4. After warming up remove the oil pressure detection plug and install the oil pressure gauge [ST2505S001(J-34301-C)].
CAUTION:
When using the oil pressure gauge, be sure to use the O-
ring attached to the oil pressure detection plug.
5. Securely engage the parking brake so that the tires do not turn.
6. Start the engine, then measure the line pressure at both idle and the stall speed.
CAUTION:

Keep the brake pedal pressed all the way down during
measurement.

When measuring the line pressure at the stall speed,
refer to AT- 5 3 , "
STALL TEST" .
7. After the measurements are complete, install the oil pressure detection plug and tighten to the specified torque.
CAUTION:

Do not reuse the O-ring.

Apply ATF to the O-ring.

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 RefillNFS000LV
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 body, immediately wipe it off and them wash it away with water
immediately.

Before servicing, disconnect actuator connector or battery cables.
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 bleed 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-10, "
Bleeding Brake System" .
