Pinpoint Test D - Any Function Inoperative

Unplug servo connector. Measure resistance between pins No. 5 and 6 of servo connector depressing each function switch and rotating steering wheel. If all resistance readings are as specified, replace servo. See CONTROL SWITCH RESISTANCES table.

If one or more (but not all) resistance readings are not as specified, replace control switch assembly. If all resistance readings are not as specified, check control switch circuit for open or short.
