- CHECK REAR SKID CONTROL SENSOR LH INSTALLATION
- Turn the ignition switch off.
*1 Rear Skid Control Sensor LH *a Correct *b Incorrect *c 8.5 N.m (87 kgf/cm, 75 in.lbf) *d No clearance - Check the rear skid control sensor LH installation.
OK
There is no clearance between the rear skid control sensor LH and the rear axle carrier LH.
The installation bolt is tightened properly.
Torque
8.5 N.m (87 kgf/cm, 75 in.lbf)
Result
Proceed to OK NG
Result:
NG
INSTALL REAR SKID CONTROL SENSOR LH CORRECTLY. Refer to INSTALLATION [12/2019 - ]
Result:
OK
See step 5
- Turn the ignition switch off.
- CHECK REAR SKID CONTROL SENSOR LH (CHECK FOR FOREIGN MATTER)
- Remove the rear skid control sensor LH, and confirm that there is no foreign matter, oil or grease on the rear skid control sensor tip LH.
OK
The rear skid control sensor tip LH is free of oil and foreign matter.
HINT:
If foreign matter of 1mm x 1mm or more is adhered to the rear skid control sensor LH, this DTC may be stored.
Result
Proceed to OK NG
Result:
NG
See step 9
Result:
OK
See step 6
- Remove the rear skid control sensor LH, and confirm that there is no foreign matter, oil or grease on the rear skid control sensor tip LH.
- CHECK REAR SPEED SENSOR ROTOR LH (CHECK FOR FOREIGN MATTER)
- Confirm that there is no foreign matter, oil or grease on the rear speed sensor rotor LH.
OK
The rear speed sensor rotor LH is free of oil and foreign matter.
HINT:
- If foreign matter of 1mm x 1mm or more is adhered to the rear speed sensor rotor LH, this DTC may be stored.
