Description
The skid control ecu measures the speed of each wheel by receiving signals from the speed sensor.
These signals are used for recognizing that all 4 wheels are operating properly. Therefore, all wheel signals must be equal.

Inspection procedure
Ok: diameter of all 4 tires are equal.
Ok: no scratches or foreign matter on the sensor tip.

Abs warning light remains on
Description
If any of the following conditions are detected, the abs warning light
remains on:
The ecu connectors are disconnected from the skid control ecu.
There is a malfunction in the skid control ecu internal circuit.

Intermediate shaft speed sensor "A"
Description
This sensor detects the rotation speed of the counter gear. By comparing the
counter gear speed signal
(nc) with the direct clutch speed sensor signal (nt), the ecm detects the shift
timing of the gears and
approximately controls the engine torque and hydraulic pressure accord ...
