Check the connectors, for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Are the connectors and terminals in good condition?
YES: An open or short circuit may be present in the power supply line to
the G and yaw rate sensor. Repair the wiring harness between G and yaw
rate sensor connector C-36 terminal 1 and ignition switch connector C-308
terminal 4. Go to Step 7.
NO: Repair or replace the damaged component(s). Then go to Step 7.
STEP 3. Measure the resistance at G and yaw rate sensor connector C-36.
1. Disconnect the G and
yaw rate sensor connector C-36, and measure at the

Q: Is the measured resistance 2 ohms or less?
YES: Go to Step 5.
NO: Go to Step 4.
STEP 4. Check G and yaw rate sensor connector C-36 for loose, corroded
or damaged terminals, or terminals pushed back in the connector.

wiring harness between G and yaw rate sensor connector C-36 terminals 4
and the body ground. Then go to Step 7.
NO: Repair or replace the damaged component(s). Then go to Step 7.
STEP 5. Check the battery.
Check the battery (Refer toBATTERY TEST
).
Q: Is the battery in good condition?
YES: Go to Step 6.
NO: Charge or replace the battery. Then go to Step 7.
STEP 6. Check the charging system.
Check the charging system (Refer to GENERATORS & REGULATORS
).
Q: Is the charging system in good condition?
YES: Replace the G and yaw rate sensor (Refer to G AND YAW RATE
SENSOR
). Then go to Step 7.
NO: Repair or replace the charging system component(s). Then go to Step
7.
STEP 7. Using scan tool MB991958, read the TCL/ASC diagnostic trouble
code.
1. Connect scan tool MB991958 to the data link connec
tor. CAUTION: To prevent damage to scan tool always turn the
ignition switch to "LOCK" (OFF) position before
connecting or disconnecting scan tool.

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.

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.

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 G and
yaw rate sensor. This is necessary because the
TCL/ASC-ECU should update the G and yaw rate
sensor neutral point.

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.
