CIRCUIT INSPECTION
DTC
C0200 / 31 - C1239 / 39Speed Sensor Circuit
CIRCUIT DESCRIPTION
The speed sensor detects wheel speed and sends the ap-
propriate signals to the ECU. These signals are used for control
of the ABS & BA & TRAC & VSC control system. The front and
rear rotors each have 48 serrations.
When the rotors rotate, the magnetic field emitted by the perma-
nent magnet in the speed sensor generates AC voltage. Since
the frequency of this AC voltage changes in direct proportion to
the speed of the rotor, the frequency is used by the ECU to de-
tect the speed of each wheel.

Detection of any of the conditions 1. through 4.:
1. At a vehicle speed of 6 mph (10 km/h) or more, pulses
are not input for 15 sec.
2. Momentary interruption of the speed sensor signal oc-
curs at least 7 times in the time between switching the
ignition switch ON and switching it OFF.
3. Continuous noise occurs into the speed sensor signals
with a vehicle speed at 12 mph (20 km/h) or more.
4. The condition that the speed sensor signal circuit is
open continues for 0.12 sec. or more.
ABS does not function
Brake pedal is not depressed
Parking brake is not set
Rear differential does not lock
Under the above conditions, when the difference in velocity
between the highest rotating and the second highest rotat-
ing wheels is within 1 mph (2 km/h), the slowest wheel ro-
tates at 0 mph (0 km/h), and the second slowest wheel
rotates at 7 mph (12 km/h) for 1 second or more.

DTC No. C0210 / 33 and C1238 / 38 are for the right rear speed sensor.
DTC No. C0215 / 34 and C1239 / 39 are for the left rear speed sensor.

4 Check sensor installation.
CHECK:
Check the speed sensor installation.
OK:
The installation bolt is tightened properly and there is
no clearance between the sensor and front steering
knuckle or rear axle carrier.
Torque: 8.0 N´m (82 kgf´cm, 71 in.´lbf)
NG Replace speed sensor.
NOTICE:
Check the speed sensor signal last (See page DI-505).
OK
5 Check speed sensor and sensor rotor serrations.
(REFERENCE) INSPECTION USING OSCILLOSCOPE
PREPARATION:
(a) Remove the skid control ECU with connectors still con-
nected.
(b) Connect the oscilloscope to each of terminals FR+ - FR-,
FL+ - FL-, RR+ - RR- or RL+ - RL- of the skid control
ECU.
CHECK:
Drive the vehicle at about 12 mph (20 km/h), and check the sig-
nal waveform.
HINT:
As vehicle speed (rpm of the wheels) increase, a cycle of
the waveform narrows and the fluctuation in the output
voltage becomes greater.
When noise is identified in the waveform on the oscillo-
scope, error signals are generated due to the speed sen-
sor rotor's scratches, looseness or foreign matter depos-
ited on it.
OK Check and replace skid control ECU.

DIAGNOSTIC TROUBLE CODE CHART
NOTICE:
When removing the part, turn the ignition switch OFF.
HINT:
Using SST 09843-18020 or 09843-18040, connect terminals Tc and E1 of the DLC1 or Tc and CG
of the DLC3.
If any abnormality is not found when inspecting parts, inspect the ECU.
If a malfunction code is displayed during the DTC check, check the circuit listed that code. For details
of each code, turn to the page referred to under the ºSee pageº for respective ºDTC No.º in the DTC
chart.
