Test G: The Key Release Interlock Actuator Is Inoperative

Pinpoint Test G: The Key Release Interlock Actuator is Inoperative
Refer to Vehicle/Diagrams, Shift Interlock for schematic and connector information.

Normal Operation
The key release interlock actuator receives fused battery voltage from smart junction box (SJB) fuse 27 (20A) along circuit SBP27 (BU/RD). Ground for the actuator is provided along circuit CDC41 (WH/BN), through the park detection switch and then along circuit GD143 (BK/VT). When the transmission selector lever is placed in PARK, the park detection switch closes and circuit CDC41 (WH/BN) is connected to circuit GD143 (BK/VT), this grounds the key release actuator and prevents the key from being removed.

This pinpoint test is intended to diagnose the following:
^ Wiring, terminals or connectors
^ Key release interlock actuator
^ Park detection switch (part of the transmission selector lever assembly)
