Pinpoint Test D: The Illuminated Entry Is Inoperative When Using The Remote Keyless Entry (RKE) Transmitter
Normal Operation
The illuminated entry provides interior lighting when the Smart Junction Box (SJB) receives an UNLOCK request from the Remote Keyless Entry

(GN/BU).
This pinpoint test is intended to diagnose the following:
-
