RL Wheel Speed |
(d) Start the engine and perform a road test.
(e) 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.
OK | USE SIMULATION METHOD TO CHECK |
NG | REPLACE REAR AXLE HUB AND BEARING ASSEMBLY LH |
