Tester Display Measurement Item Range Normal Condition Diagnostic Note RL Wheel Speed Rear wheel speed sensor LH reading Min.: 0.0 km/h (0.0 mph), Max.: 6553.5 km/h (4072 mph) Vehicle stopped: 0.0 km/h (0.0 mph) When driving at constant speed: No large fluctuations Chassis > Brake/EPB > Data List
Tester Display RL Wheel Speed - Start the engine and perform a road test.
- Check that the value of RL Wheel Speed changes in accordance with vehicle speed when accelerating from 0 km/h to 20 km/h (0 mph to 12 mph).
OK
The value of RL Wheel Speed changes in accordance with vehicle speed.
HINT:
If the result of the road test is within the specified range, it is possible that this DTC was stored due to a particular situation such as brake drag, wheelspin or wheel lockup.

- CHECK REAR SPEED SENSOR LH INSTALLATION
- Check the rear speed sensor LH installation.
*1 Rear Speed Sensor LH *a Correct *b Incorrect *c 8.5 N.m *d No clearance OK
There is no clearance between the rear speed sensor LH and the rear axle carrier LH.
The installation bolt is tightened properly.
