Q: Is the measured resistance 2 ohms or less?
YES: Go to Step 5.
NO: Go to Step 4.
STEP 4. Check steering wheel sensor connector C-312 for loose, corroded
or damaged terminals, or terminals pushed back in the connector.

YES: An open circuit may be present in the ground circuit. Repair the
wiring harness between steering wheel sensor connector C-312 terminals 5
and the body ground. Then go to Step 8.
NO: Repair or replace the damaged component(s). Then go to Step 8.
STEP 5. Check the battery.
Check the battery (Refer to BATTERY TEST
).
Q: Is the battery in good condition?
YES: Go to Step 6.
NO: Charge or replace the battery. Then go to Step 8.
STEP 6. Check the charging system.
Check the charging system (Refer to GENERATORS & REGULATORS
).
Q: Is the charging system in good condition?
YES: Go to Step 7.
NO: Repair or replace the charging system component(s). Then go to Step
8.
STEP 7. Retest the system.
Q: Can the steering wheel sensor communicate with the scan tool (MUT-
III Sub Assembly)?
YES: It can be assumed that this malfunction is intermittent. Refer to
HOW TO COPE WITH INTERMITTENT MALFUNCTIONS
.
NO: Replace the steering wheel sensor. Then go to Step 8.
STEP 8. Retest the system.
Q: Can the steering wheel sensor communicate with the scan tool (MUT-
III Sub Assembly)?
YES: The
procedure is com
plete.

ON-VEHICLE SERVICE WHEEL SPEED SENSOR OUTPUT VOLTAGE MEASUREMENT Required Special Tool:
MB991219: Inspection Harness
1. Release the parking brake and lift up the vehicle.
2. Disconnect the TCL/ASC-ECU connector A-32, and then use special tool
MB991219 to measure the out
put volta
ge at the harness side connector.

3. Manually turn the wheel to be measured 1/2 to 1 turn/second. Measure the
output voltage with a voltmeter or oscilloscope.
Output voltage:
Minimal voltmeter reading: 42 mV Maximum voltmeter reading: 300 mV Minimal oscilloscope reading: 120 mV Maximum oscilloscope reading: 600 mV
Probable causes of low output voltage Wheel speed sensor pole piece-to-Wheel speed rotor clearance too large Faulty Wheel speed sensor
4. To observe the waveform with an oscilloscope: Front Wheels: Shift into "D" range and drive the wheels. Rear Wheels: Turn the wheels manually at a constant speed NOTE: Check the connection of the sensor harness and
connector before using the oscilloscope.
NOTE: The output waveform is low when the wheel speed is
low. Similarly, it will be higher as the wheel speed
increases. Waveform may also be observed by driving
the vehicle.

HYDRAULIC UNIT CHECK Required Special Tools:

MB991824: Vehicle Communication Interface (V.C.I.) MB991827: MUT-III USB Cable MB991910: MUT-III Main Harness A
NOTE: The Wheel speed sensor cable moves in relation to motion
of the front or rear suspension. Therefore, it is likely that it
has an open circuit only when driving on rough roads but it
functions normally when driving on smooth roads. It is
recommended to observe sensor output voltage waveform
also under special conditions, such as driving on a rough
road.

3. Turn the ignition switch to the "ON" position.
4. Select "Interactive Diagnosis".
5. Select "Special function".
6. Select "G and yaw rate sensor".
7. Select "Calibration".
8. Turn the ignition switch to the "LOCK" (OFF) position.
9. Disconnect scan tool MB991958. STEERING WHEEL SENSOR CALIBRATION Required Special Tools:

1. Park the vehicle on a level surface.
2. Connect scan tool MB991958 to the data link connec
tor. CAUTION: If the work below is done, finally calibrate the
steering wheel sensor. This is necessary because the
TCL/ASC-ECU should update the steering wheel
sensor neutral point.
Front alignment adjustment Steering wheel sensor removal and installation ASC-ECU replacement
CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
disconnecting scan tool MB991958.
