When shifting the selector lever to "D" range, apply the brakes so that the vehicle does not move
forward.
Driving tests always need two persons: one driver and one observer.
NOTE: *:After the inspection is completed, disconnect the throttle position sensor connector, and then delete
the diagnostic trouble code using use of Diagnostic Tool MB991958. (Refer to P.17-11).

If the air intake duct is removed from the throttle body take great care to keep fingers away
from the throttle plate. The drive motor has very high torque and is capable of random move-
ment at any time. Do not under any circumstances activate the throttle plate by hand.
When removing the throttle body from the intake manifold disconnect the wiring first. During
replacement connect the wiring last.
Do not activate the throttle body using a DC suppy to test the motor,as permanent damage to
the throttle body will result.

1. Remove the auto-cruise control switch. (Refer to P.17-75).
2. Measure the resistance between terminal 2 and terminal 3
when each of the "COAST/SET", "ACC/RES", "CANCEL"
and "CRUISE" (MAIN) switches is pressed. If measure
values measured at the time correspond to those in the table
below, the resistance values are correct.

Required Special Tool:
MB995061: Purge Flow Indicator
1. Disconnect the purge hose from the evaporative emission
(EVAP) purge solenoid, and connect special tool MB995061
between the EVAP purge solenoid and the purge hose.
2. Before inspection, set the vehicle in the following conditions:
Engine coolant temperature: 80 95C (176 203F)
Lights, electric cooling fan and accessories: OFF
Transaxle: P range
3. Run the engine at idle for more than four minutes.
4. Check the purge flow volume when engine is revved
suddenly several times.
Standard value: Momentarily 20 cm
3/s (2.5 SCFH) or
more.
5. If the purge flow volume is less than the standard value,
check it again with the vacuum hose disconnected from the
EVAP canister. If the purge flow volume is less than the
standard value, check the vacuum port and the vacuum
hose for clogging. Also check the EVAP purge solenoid. If
the purge flow volume is at the standard value, replace the
EVAP canister.
EVAPORATIVE EMISSION PURGE SOLENOID
CHECK
M1173001700289
1. Disconnect the vacuum hose (black, black with red paint
mark) from the evaporative emission (EVAP) purge
solenoid.
NOTE: When disconnecting the vacuum hose, always place
an identification mark so that it can be reconnected at its
original position.
2. Disconnect the harness connector.
3. Connect a hand vacuum pump to nipple (A) of the EVAP
purge solenoid (refer to the illustration at left).
4. As described in the chart below, check airtightness by
applying a vacuum with voltage applied directly from the
battery to the EVAP purge solenoid valve and without
applying voltage.

4. If the inner shaft is hard to remove from the transaxle, strike
the bracket assembly lightly with a plastic hammer and
remove the inner shaft.
Do not apply pressure to the wheel bearing by the vehicle
weight to avoid possible damage when the drive shaft is
removed. If, however, vehicle weight must be applied to
the bearing to move the vehicle, temporarily secure the
wheel bearing by using special tools MB991000 and
MB990998.

>>A<< DRIVE SHAFT AND INNER SHAFT ASSEM-
BLY RH DRIVE SHAFT INSTALLATION
When installing the drive shaft or the drive shaft and inner
shaft assembly, be careful that the spline part of the drive
shaft or the drive shaft and inner shaft assembly do not
damage the oil seal.
.
>>B<< DRIVE SHAFT NUT INSTALLATION
1. Be sure to install the drive shaft washer in the specified
direction.
Before securely tightening the drive shaft nuts, make sure
there is no load on the wheel bearings. Otherwise the
wheel bearing will be damaged.
2. Using special tool MB990767, tighten the drive shaft nut to
the specified torque.
