VOLTAGE AND SIGNAL CHECK AT ABS-ECU
(A-02) USING OSCILLOSCOPE
NOTE: If the ABS-8 ECU or the active wheel speed
sensor are disconnected, or if the wiring is an open/
short circuit, the ABS 8 ECU will shut off power sup-
ply to the respective wheel speed sensor. All other
wheel speed sensors will operate normally. To
restore the power supply, the ignition switch must be
turned to the "OFF" position then to the "ON" position
again..
WHEEL SPEED SENSOR AIR GAP:
Sensor air gap: (0.2mm - 0.85mm).
.
Measure supply voltage for wheel speed sensor using an
oscilloscope.
(1) ABS-ECU must remain connected.
(2) Wheel speed sensors must emain connected
(3) Remove ABS connector protection cap to access terminal
location from the rear of connector for back-probing.
(4) Using probe (MB991222) , backprobe the wheel speed
sensor voltage supply circuit terminals (16, 9, 6 and 8) at
the ABS-ECU connector (A-02) individually.
(5) Connect oscilloscope (as per figure 1) shows, to the
appropriate terminal positions and check supply voltage
individually with scope.

(7) The recommended Supply Voltage at terminals 16, 9, 6,
and 8 are:
Set value: 10.0Volts - 14.5Volts
Q: Is the supply voltage within the set value?
YES : Check wheel speed sensor signal at ABS-ECU using
an oscillopscope
NO :
Refer to Power supply systemP.35B-63
Refer to Motor supply systemP.35B-48
Refer to Valve relay systemP.35B-56
Measure wheel speed sensor signals using an
oscilloscope.
NOTE: To check connections of the wheel speed sensors,
remove the rear seat to access the rear wheel speed sen-
sor connectors, and remove inner front guard (splash
shield) to access the front wheel speed sensors.
(1) Wheel speed sensor must remain connected to measure
active sensor.
(2) ABS-ECU must remain connected.
(3) Remove ABS connector protection cap to access terminal
location from the rear of connector for back-probing.
(4) Using probe (MB991222), backprobe the wheel speed
sensor signal circuit terminals (5, 10, 17, 19), and check
individually at the ABS-ECU connector A-02
(5) The wheel to be tested must be free to turn by hand or be
driven by brake dynamometer
(6) Connect oscilloscope (as per figure 2) shows, to the
appropriate terminal positions and check sensor operation
individually with scope.

Connect oscilloscope to FL sensor signal terminal (5) at
ABS-ECU (A-02)
Connect oscilloscope to FR sensor signal terminal (10)
at ABS-ECU (A-02)
Connect oscilloscope to RL sensor signal terminal (17)
at ABS-ECU (A-02)
Connect oscilloscope to RR sensor signal terminal (19)
at ABS-ECU (A-02)
(7) Recommended Oscilloscope setting:
Y-axis: 2Volts
X-axis: 100ms
(8) Turn the ignition switch to the "ON" position.
(9) Turn wheel by hand at approximately 1 revolution per
second (r/sec) or drive on brake dynamometer at 5km/h.
The measurement reading of the active wheel speed sen-
sors on the oscilloscope should correspond to figure 3
below.
NOTE: If the oscilloscope signal shape is correct and wheel
sensor air gap is within specification, but the voltage values are
either higher or lower as shown in the table below, the wheel
speed sensor must be changed.

ON-VEHICLE SERVICE
TRACTION CONTROL SYSTEM (TCL)13C-48
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.13C-3).
2. Turn the ignition switch to the "ON" position.
The engine speed increases after the actuator test
because the actuator test continues for only three sec-
onds. Therefore, release the accelerator pedal immedi-
ately.
3. Use diagnostic tool MB991958 to check the actuator test.
(Refer to P.13C-3).
Item 09: Engine TCL Drive.
When the accelerator pedal is depressed at the same
time that the button for actuator test item 09 displayed
on diagnostic tool MB991958 is pressed, the system
prevents the engine speed from rising for three sec-
onds.
4. Turn the ignition switch to the "LOCK" (OFF) position.
5. Disconnect diagnostic tool MB991958.
6. If defective, repair it. (Refer to P.13C-34, TCL diagnosis

TCL SWITCH CHECKM1136001700024
1. Remove the TCL switch. (Refer to P.13C-49).
2. Measure the resistance between terminal 1 and terminal 2
when the TCL switch is pressed or released. If the values
measured at the time correspond to those in the table below,
the resistance values are correct.

AUTO-CRUISE CONTROL
GENERAL DESCRIPTIONM1172000100281
By using the auto-cruise control system, the driver
can select and maintain a desired cruising speed
[between 40 km/h (25 mph) and 200 km/h (124
mph)] without depressing the accelerator pedal.NOTE: If engine speed reaches and exceeds 6000
r/min the Auto Cruise Control System will be can-
celled automatically.

AUTO-CRUISE CONTROL SYSTEM DIAGNOSIS
INTRODUCTION TO AUTO-CRUISE CONTROL SYSTEM DIAGNOSISM1172003300251
The auto-cruise control system allows driving without
stepping on the accelerator pedal by setting a ran-
dom speed between 40 km/h (25 mph) and 200 km/h
(124 mph). Problems in this system can be investi-
gated by the following methods.Auto-cruise control system diagnostic
trouble codes
The auto-cruise control system consists of the
Engine ECU, control switches and sensors. The con-
trol switches and sensors monitor the state of the
vehicle. The Engine ECU controls the throttle valve
opening angle in the throttle body in accordance with
the input signals from the switches and sensors. If
the Engine ECU detects a problem on any of those
