pushed back in the connector.
Q: Are the connectors and terminals in good condition?
YES: Go to Step 10.
NO: Repair or replace the damaged component(s). Then go to Step 13 .
STEP 10. Check the following harness wires.
The wire between ABS-ECU connector A-02 (terminal 8) and G-sensor
connector
C-23
(terminal 3
)

Q: Is any harness wire damaged?
YES: Repair the harness wire. Then go to Step 13 .
NO: Go to Step 11.
STEP 11. Recheck for diagnostic trouble code after the G-sensor is
replaced.
Replace the G-sensor, and check whether DTC C1381, C1382 or C1383 is
reset.
1. Replace the G-sensor.
2. Connect scan tool MB991958 to the data link connec
tor. 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.

ON-VEHICLE SERVICE ABS SENSOR OUTPUT VOLTAGE MEASUREMENT Required Special Tool:
MB991219: Inspection Harness
1. Release the parking brake and lift up the vehicle.
2. Disconnect the ABS-ECU connector A-02, and then use special tool
MB991219 to measure the out
put volta
ge at the harness side connector.
NOTE: For vehicles with ASC, refer to WHEEL SPEED SENSOR
OUTPUT VOLTAGE MEASUREMENT
.

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 oscillosco
pe readin
g: 600 mV NOTE: Check the connection of the sensor harness and
connector before using the oscilloscope.

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
POINTS IN WAVEFORM MEASUREMENT Fig. 150: Identifying Points In Waveform Measurement

Courtesy of MITSUBISHI MOTOR SALES OF AMERICA. 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 ABS 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
