Description
Rear Differential
Outline
The Real-time 4WD-Dual Pump System model has a hydraulic clutch and a differential mechanism in the rear differential
assembly. Under normal conditions, the vehicle is driven by the front wheels. However, depending on to the driving force
of the front wheels and the road conditions. the system instantly transmits appropriate driving force to the rear wheels
without requiring the driver to switch between 2WD (tront wheel drive) and 4WD (four wheel drive). The switching mecha-
nism between 2WD and 4WD is integrated into the rear differential assembly to make the system light and compact.
ln addition, the dual-pump system switches off the rear-wheel-drive force when braking in a forward gear. This allows the
braking system to work properly on models equipped with an Anti-lock Braking System (ABS).
Construction
The rear differential assembly consists of the torque control differential case assembly and the rear differential carrier
assembly. The torque control differential case assembly consists of the differential clutch assembly, the companion
flange, and the oil pump body assembly. The rear differential carrier assembly consists of the differential mechanism. The
differential drive and driven gears are hypoid gears.
The oil pump body assembly consists of the front oil pump, the rear oil pump, the hydraulic control mechanism, and the
clutch piston. The clutch piston has a disc spring that constantly provides the differential clutch assembly with a preset
torque to Drevent abnormal sound.
The clutch guide in the differential clutch assembly is connected to the propeller shaft via the companion flange, and it
receives the driving force lrom the transfer assembly. The clutch guide rotates the clutch plate and the front oil pump in
the oil pump body.
The clutch hub in the differential clutch assembly has a clutch disc that is splined with the hypoid drive pinion gear. The
hypoid drive gear drives the rear oil pump.
The front and rear oil pumps are trochoidal pumps. The rear oil pump capacity is 2.5 percent larger that the front oil pump
to handle the rotation difference between the front and rear wheels caused by worn front tires and tight corner braking.
The oil pumps are designed so the fluid intake works as a fluid discharge when the oil pumps rotate in reverse. Genuine
Honda CVT fluid is used instead of differential fluid.
Operation
When there is a difference in rotation speed between the front wheels (clutch guide) and rear wheels (hypoid driven gear),
hydraulic pressure from the front and rear oil pumps engages the differential clutch, and drive force from the transler
assembly is applied to the rear wheels.
The hydraulic pressure control mechanism in the oil pump body selects 4WD mode when the vehicle is started abruptly,
or when accelerating in a forward or reverse gear (causing rotation difference between the front and rear wheels). or
when braking in reverse gear {when decelerating). lt switches to 2WD mode when the vehicle is driven at a constant speed
in forwar! or reverse gear (when there is no rotation difference between the front and rear wheels), or when braking in a
fo rwa rd gear (when decelerating).
To protect the system, the differential clutch assembly is lubricated by hydraulic pressure generated by the oil pumps in
both 4WD and 2WD modes. Also, the thermal switch relieves the hydraulic pressure on the clutch piston and cancels 4WD
mode if the temDerature of the differential fluid rises above normal.

Troubleshooting
General Troubleshootin g
Check the following before you begin:
. Has the suspension been modified in a way that would affect steering?
. Are tire sizes, tire variety and air pressure correct?
. ls the steering wheel original equipment or equivalent?
. ls the power steering pump belt properly adjusted?
. ls steering fluid reservoir filled to proper level?
. ls the engine idle speed correct and steady?
Hard Steering (Check the power assist, see page 17-12. lf the force is over 29 N (3.0 kgl 6.6 lbfl, proceed with this troubleshooting.i
Abnormalthiidpressure (Iluidpressure is toohigh)

Check the pump fluid pressure(see page 17-16 or 17-17).Measure steady state lluid pres-
sure at idle with the pressure con-trol valve and the shut-off valve (it
so equipped) fully open.The fluid pressure should be 1,500kPa (15 kgf/cm,,213 psi)or less.
Normal
Check the flow control valve (see page 17 26).. Check the valv€ lor smooth movement in the hous-ing.. Check the relief valve for leaks.
Check the pump fluid pressure(see page 17-16 or l7-17).Measure pump relief pressure atidle with the pressure controlvalve and the shut'off valve lil soequipped) fully closed.The fluid pressure should be 6,9007,800 kPa (70 - 80 kgflcm,, 1,000- 1,140 psi).

Wheel Alignment
Caster
For proper inspection/adjustment of the wheel align-ment, check and adjust these items before checkinq thealignment:
. Check that the suspension is not modified.. Check the tire size and tire pressure.
. Check th( runout of the wheels and t;res,. Check the suspension ball joints. (Hold a wheel withyour hands, and move it up and down and right andleft to check for wobbling.)
Inspection
Use commercially-available computerized four wheelalignment equipment to measure wheel alignment (cast-
er, camber, toe, and turning angle). Follow the equip-ment manufacturer's instructions.
Check the caster angle.
Caster angle: 2'10':t 1"
lf out of specification, check for bent or damagedsuspension components.

- lf adjustment is required, go on to step 4.
- lf no adjustment is required, remove alignment

Loosen the tie-rod locknuts, and turn both tie-rods
in the same direction until the front wheels are
pointing straight ahead.
5.Turn both tie-rods equally until the toe reading on
the wheel alignment computer is correct.
After adjusting, tighten the tie-rod locknuts and
reposition the tie-rod boots if they are twisted or
displaced.

Example: After the rear toe inspection, the wheel is 2
mm (0.08 in) out of the specification.- Move the arm so the adjusting bolt moves 2 mm
{0.08 in) inward from the position recorded before the
adjustment.- The distance the adjusting bolt is moved should be
equal to the amount out-of-specification.

Anti-lock Brake System (ABS)
Features/Construction
When the brake pedal is pressed during driving, the wheels can lock before the vehicle comes to a stop. In such an event,
the maneuverability of the vehicle is reduced if the front wheels are locked, and the stability of the vehicle is reduced if the
rear wheels are locked, creating an extremely unstable condition. The ABS precisely controls the slip rate of the wheels to
ensure maximum grip force from the tires, and it thereby ensures maneuverbility and stability of the vehicle.
The ABS calculates the slip rate of the wheels based on the vehicle speed and the wheel speed, then it controls the brake
fluid pressure to attain the target slip rate.

A/C System Service
Evacuation
Use only service equipment that is U.L.-listed and is cer-tified to meet the requirements of SAE J2210 to removeHFC-134a {R-134a)from the air conditioner system.
CAUTION: Exposure to air conditioner refrigerant andlubricant vapor or mist can irrhate eyes, noso and throat.Avoid breathing the air condhioner retrigerant and lubri-cant vapor or mist.
lf accidental system discharge occu.s. ventilate workarea before resuming service.
R 134a service equipment or vehicle air conditioner sys-tems should not be pressure tested or leak tested withcompressed arr.
!@ some mixtures of air and R-134a hsvo beenshown to be combustible at elevated pressures and canresult in tire or explosion causing iniury ot property
damage. Never use compressed air to pressure test R-134a service equipment or vehicle air conditioner svs-tems.
Additional health and safety information may be obtainedfrom the refrigerant and lubricant manufacturers.
1, When an A,/C System has been opened to the atmo-
sphere, such as during installation or repair, it must
be evacuated using a R-l34a refrigerant recovery/
recycling/charging station. {lf the system has beenopen for several days, the receiver/dryer should bereplaced, and the system should be evacuated forseveral hours.)
Connect a R-134a refrigerant recovery/recyclin g/
charging station to the vehicle, as shown, following
the equipment manufacturer's instructions.
Evacuate the system,
lf the low-pressure does not reach more than 93.3kPa (700 mmHg,27.6 in.Hg) in 15 minutes, there isprobably a leak in the system. partially charge thesystem, and check for leaks (see Leak Test).
