DESCRIPTION
The skid control ECU (brake actuator assembly) measures the speed of each wheel by receiving signals from the speed sensors. These signals are used for recognizing whether all 4 wheels are operating properly. Therefore, all wheel signals must indicate the same speed.

PROCEDURE
1. INSPECT 3RD GEAR THRUST CLEARANCE
(a) Using a dial indicator, measure the 3rd gear thrust clearance.
Standard clearance:
0.200 to 0.490 mm (0.0079 to 0.0192 in.)
If the clearance is outside the specification, replace the 3rd gear,
thrust washer, c ...
