DESCRIPTION
Refer to DTC C0200/31 C0200.
DTCs C1273/73, C1274/74, C1277/77 and C1278/78 can be deleted when the speed sensor sends a vehicle speed signal or the test mode ends. DTCs C1273/73, C1274/74, C1277/77 and C1278/78 are output only in the test mode.
HINT:
- DTC C0210/33 and C1238/38 relate to the skid control sensor RH.
- DTC C0215/34 and C1239/39 relate to the skid control sensor LH.

INSPECTION PROCEDURE
NOTE: Check the speed sensor signal in test mode after cleaning or replacement .
PROCEDURE
1. CHECK HARNESS AND CONNECTOR (MOMENTARY INTERRUPTION)
(a) Using the Data List of Techstream, check for any momentary interruption in the wire harness corresponding to a DTC .
ABS / VSC / TRAC:
OK:
There are no momentary interruptions.
HINT: Perform this inspection before removing the sensor and connector.
NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
2. READ VALUE USING TECHSTREAM (REAR SPEED SENSOR)
(a) Check the Data List for proper functioning of the rear speed sensor.
ABS / VSC / TRAC:
OK:
There is almost no difference between actual wheel speed and displayed speed value.
HINT: There is a tolerance of +-10% in the speedometer indication.
NG -- INSPECT SKID CONTROL SENSOR OR REAR SPEED SENSOR (INSTALLATION)
OK -- Continue to next step.
3. PERFORM TEST MODE INSPECTION (SIGNAL CHECK)
(a) Perform a test mode inspection and check for DTCs .
OK:
No DTCs output.
NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
4. RECONFIRM DTC
(a) Clear the DTC(s) .
(b) Start the engine.
(c) Drive the vehicle at a speed of 20 km/h (12 mph) or more for at least 60 seconds.
(d) Check if the same DTC(s) is output .
Result
B -- RECONFIRM DTC
A -- END
5. INSPECT SKID CONTROL SENSOR OR REAR SPEED SENSOR (INSTALLATION)
(a) Check the speed sensor installation.
OK:
for 2WD
There is no clearance between the sensor and rear axle carrier.
for 4WD
The installation bolt is tightened properly and there is no clearance between the sensor and rear axle carrier.
Torque: 8.5 Nm (87 kgf-cm, 75 in-lbf)
HINT: Check the speed sensor signal after the replacement .
NG -- CHECK AND REPLACE SKID CONTROL SENSOR OR REAR SPEED SENSOR
OK -- Continue to next step.
6. CHECK SKID CONTROL SENSOR OR REAR SPEED SENSOR (TIP)
(a) Remove the skid control sensor (for 2WD) or rear speed sensor (for 4WD).
(b) Check the sensor tip.
OK:
No scratches or foreign matter on the sensor tip.
NG -- CLEAR OR REPLACE SKID CONTROL SENSOR OR REAR SPEED SENSOR
OK -- Continue to next step.
7. CHECK WIRE HARNESS (SKID CONTROL ECU - REAR SPEED SENSOR)
(a) Disconnect the A19 ECU connector.
(b) Disconnect W1 and V1 sensor connectors for 2WD.
Disconnect K23 and K22 sensor connectors for 4WD.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:
for 2WD (LH Side)
for 2WD (RH Side)
for 4WD (LH Side)
for 4WD (RH Side)
NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
8. CHECK SKID CONTROL ECU (SENSOR INPUT VOLTAGE)
(a) Disconnect the W1 and V1 sensor connectors for 2WD.
Disconnect the K23 and K22 sensor connectors for 4WD.
(b) Measure the voltage of the wire harness side connectors.
Standard voltage:
for 2WD
for 4WD
NG -- REPLACE ABS AND TRACTION ACTUATOR ASSEMBLY
OK -- Continue to next step.
9. RECONFIRM DTC
(a) Clear the DTC(s) .
(b) Start the engine.
(c) Drive the vehicle at a speed of 20 km/h (12 mph) or more for at least 60 seconds.
(d) Check if the same DTC(s) is output .
Result
B -- END
A -- Continue to next step.
10. REPLACE SKID CONTROL SENSOR OR REAR SPEED SENSOR
(a) Replace the skid control sensor (2WD) or rear speed sensor (4WD).
NEXT -- Continue to next step.
11. RECONFIRM DTC
(a) Clear the DTC(s) .
(b) Start the engine.
(c) Drive the vehicle at a speed of 20 km/h (12 mph) or more for at least 60 seconds.
(d) Check if the same DTC(s) is output .
Result
B -- END
A -- REPLACE ABS AND TRACTION ACTUATOR ASSEMBLY
