CIRCUIT OPERATION
The steering wheel sensor is energized by the ignition switch (IG2) through
multi-purpose fuse 13 and the steering wheel sensor terminal 2. If the power supply to the steering wheel sensor has failed, scan tool (MUT-III
Sub Assembly) will not be able to communicate with it.
TROUBLESHOOTING HINTS (The most likely causes for this case:)
Damaged wiring harness or connector Defective battery Charging system failed Malfunction of the steering wheel sensor
DIAGNOSIS Required Special Tools:
MB991958: Scan Tool (MUT-III Sub Assembly)
MB991824: Vehicle Communication Interface (V.C.I.) MB991827: MUT-III USB Cable MB991910: MUT-III Main Harness A
MB991952: ABS Check Harness
STEP 1. Measure the volta
ge at steerin
g wheel sensor connector C-312
.

Q: Is battery positive voltage (approximately 12 volts) present?
YES: Go to Step 3.
NO: Go to Step 2.
STEP 2. Check the following connectors.
Junction block connector C-211 and C-215

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 steering wheel sensor. Repair the wiring harness between steering
wheel sensor connector C-312 terminal 2 and ignition switch connector C-
308 terminal 4. Go to Step 8.
NO: Repair or replace the damaged component(s). Then go to Step 8.
STEP 3. Measure the resistance at steering wheel sensor connector C-312.
1. Disconnect the steering sensor connector C-312, and measure at the
harness side connector.

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.
