Nissan Maxima Service and Repair Manual: Power steering fluid
Inspection
FLUID LEVEL
- Check fluid level with engine stopped.
- Make sure that fluid level is between MIN and MAX.
- Fluid levels at HOT (A) and COLD (B) are different. Do not confuse
them.

HOT (A) : Fluid temperature 50 - 80 C (122- 176F)
COLD (B) : Fluid
temperature 0 - 30C (32- 86F)
CAUTION:
- The fluid level should not exceed the MAX line. Excessive
fluid will cause fluid leakage from the cap.
- Do not reuse drained power steering fluid.
- Recommended fluid is Genuine Nissan PSF or equivalent.
FLUID LEAKAGE

Check hydraulic connections for fluid leakage, cracks, damage, looseness,
or wear.
- Run engine until the fluid temperature reaches 50 - 80 C (122 -
176F) in reservoir tank, and keep engine speed at idle.
- Turn steering wheel several times from full left stop to full
right stop.
- Hold steering wheel at each lock position for five seconds and
carefully, check for fluid leakage.
CAUTION:
Do not hold the steering wheel in a locked position for more than 10
seconds. (There is the possibility that oil pump may be damaged.)
- If fluid leakage at connections is noticed, then loosen flare nut and
then retighten. Do not overtighten connector as this can damage O-ring,
copper sealing washers and connector.
- If fluid leakage from oil pump is noticed, check oil pump. Refer
to ST-28, "Removal and Installation".
- Check steering gear boots for accumulation of fluid indicating
leakage from steering gear.
Draining
- Disconnect both high and low pressure lines from power steering gear.
- Drain into a suitable container.
Refilling
FILLING HYDRAULIC SYSTEM
- Fill power steering reservoir while checking fluid level.
- Bleed air from hydraulic system.
- Check for fluid leaks.
AIR BLEEDING HYDRAULIC SYSTEM
If air bleeding is not complete, the following symptoms can be observed.
- Bubbles are created in reservoir tank.
- Clicking noise can be heard from oil pump.
- Excessive buzzing in the oil pump.
NOTE: Fluid noise may occur in the steering
gear or oil pump. This does not affect performance or durability of the
system.
- Turn steering wheel several times from full left stop to full right stop
with engine off.
CAUTION: Do not allow
the fluid level to drop below the MIN line.
- Start engine and hold steering wheel at each lock position for
three seconds at idle to check for fluid leakage
- Repeat step 2 above several times at approximately three second
intervals.
CAUTION: Do not hold the
steering wheel in a locked position for more than 10 seconds. (There is the
possibility that oil pump may be damaged.)
- Check fluid for bubbles or white contamination.
- Stop engine if bubbles or white contamination is present. Perform
step 2 and 3 above after waiting until bubbles or white contamination
disappear.
- Stop the engine, and then check fluid level.

Description
IPDM E/R transmits the push-button ignition switch status via CAN
communication to BCM. BCM receives
push-button ignition switch status by hardwire input. BCM compares the 2 signals
for mismatch.
