8) Using ammeter (2), check that P/S motor current (1)
is as following table with idling engine. If check result
is not satisfactory, check P/S control module for
torque sensor signal and P/S motor output referring
to “Inspection of P/S Control Module and Its
Circuits”. If they are OK, replace steering gear case
assembly.
NOTE
When P/S motor is cold condition (that is,
armature coil of P/S motor is not heated),
motor current in the following table can be
measured
