DIAGNOSIS
Required Special Tools:
MB991958: Diagnostic Tool (MUT-III Sub Assembly)
MB991824: V.C.I.
MB991827: MUT-III USB Cable
MB991910: MUT-III Main Harness A
STEP 1. Using Diagnostic Tool MB991958, read the
diagnostic trouble code.
To prevent damage to Diagnostic Tool MB991958, always
turn the ignition switch to the "LOCK" (OFF) position
before connecting or disconnecting Diagnostic Tool
MB991958.
(1) Connect Diagnostic Tool MB991958 to the data link
connector. (Refer to P.17-11).
(2) Turn the ignition switch to the "ON" position.
(3) Check for A/T system diagnostic trouble code. (Refer to
GROUP 23A, A/T Diagnosis
Diagnostic Function How
to Read and Erase Diagnostic Trouble Code P.23A-13).
(4) Turn the ignition switch to the "LOCK" (OFF) position.
(5) Disconnect Diagnostic Tool MB991958.
Q: Is any DTC set?
YES : Diagnose the A/T system. (Refer to GROUP 23A, A/T
Diagnosis
Diagnostic Trouble Code Chart
P.23A-34). Then go to Step 4.
NO : Go to Step 2.

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.

ON-VEHICLE SERVICE
AUTO-CRUISE CONTROL SWITCH CHECKM1172001200054
AUTO-CRUISE CONTROL MAIN SWITCH CHECK
1. Turn the ignition switch to the "ON" position.
2. Check that the "CRUISE" indicator lamp within the
combination meter illuminates when the "CRUISE" (MAIN)
switch is switched "ON".
AUTO-CRUISE CONTROL SETTING
1. Switch "ON" the "CRUISE" (MAIN) switch.
2. Drive at the desired speed, above approximately 40 km/h.
3. Push the auto-cruise control switch in the direction of the
arrow.
4. Check to be sure that when the switch is released the speed
is the desired constant speed.
NOTE: If the vehicle speed decreases to approximately 15
km/h below the set speed because of climbing a hill for
example, it is normal for the auto-cruise control to be can-
celled.

AUTO-CRUISE CONTROL
ENGINE AND EMISSION CONTROL17-72
SPEED-INCREASE SETTING
1. Set to the desired speed.
2. Push the auto-cruise control switch in the direction of the
arrow.
3. Check to be sure that acceleration continues while the
switch is held, and that after it is released the constant
speed at the time when it was released becomes the driving
speed.
NOTE: Acceleration can be continued even if the vehicle
speed has passed the high-speed limit [approximately 170
km/h ]. But the speed when the auto-cruise control switch is
released will be recorded as the high-speed limit.
SPEED-REDUCTION SETTING
1. Set to the desired speed.
2. Push the auto-cruise control switch in the direction of the
arrow.
3. Check to be sure that deceleration continues while the
switch is pressed, and that after it is released the constant
speed at the time when it was released becomes the driving
speed.
NOTE: When the vehicle speed reaches the low limit
[approximately 40 km/h ] during deceleration, the
auto-cruise control will be cancelled.
RETURN TO THE SET SPEED BEFORE
CANCELLATION AND AUTO-CRUISE CONTROL
CANCELLATION
1. Set the auto-cruise speed control.
2. When any of the following operations are performed while at
constant speed during auto-cruise control, check if normal
driving is resumed and deceleration occurs.
(1) The auto-cruise control switch is pulled in the direction of
the arrow.
(2) The brake pedal is depressed.
(3) The selector lever is moved to the "N" range.
3. At a vehicle speed of 40 km/h or higher, check if when the
"ACC/RES" switch is switched ON, the vehicle speed
returns to the speed before auto-cruise control driving was
cancelled, and constant speed driving occurs.
4. When the "CRUISE" (MAIN) switch is turned to the "OFF"
while driving at constant speed, check if normal driving is
resumed and deceleration occurs.

GENERAL DESCRIPTION
FRONT AXLE26-2
GENERAL DESCRIPTIONM1261000100370
The front axle consists of front hubs, knuckles, wheel
bearings and drive shafts, and has the following fea-
tures:
The wheel bearing incorporates double-row
angular contact ball bearing for reduced friction.
The front wheel hub assembly combines the hub,
wheel bearing, and oil seal in a single unit for
fewer parts, better durability, improved assembly
precision, and better structural organization.
The driveshaft incorporates BJ-PTJ type constant
velocity joints with high transmission efficiency for
low vibration and noise.
Due to the use of the inner shaft and bracket
assembly, the right and left drive shafts are
approximately the same in length. This reduces
noise, vibration and torque steer.L-RH>
The dynamic damper is mounted on the LH drive-
shaft.
ABS rotor for detecting the wheel speed is
press-fitted to the BJ.

TROUBLESHOOTING STRATEGYM1261005600240
Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will be sure that you
have exhausted most of the possible ways to find a front axle fault.
1. Gather information from the customer.

REMOVAL AND INSTALLATIONM1261001700386
For vehicles with ABS, do not strike the ABS rotors installed to the BJ outer race of drive shaft
against other parts when removing or installing the drive shaft. Otherwise the ABS rotors will be
damaged.
For vehicles with ABS, be careful not to strike the pole piece at the tip of the front wheel speed
sensor with tools during servicing work.
