Test G: DTC B1352 - Ignition Key-in Circuit Failure, the Ignition Key Cannot Be Removed from the Ignition Cylinder or the Ignit

Pinpoint Test G: DTC B1352 - Ignition Key-in Circuit Failure, the Ignition Key Cannot Be Removed from the Ignition Cylinder or the Ignition Key Can Be Removed from the Ignition Cylinder Regardless of Gear Selector Position
Refer to Vehicle/Diagrams, Power Distribution/SJB for schematic and connector information.

Normal Operation
When the ignition key is inserted into the ignition lock cylinder, an internal switch in the ignition switch assembly closes and battery voltage is sent to the smart junction box (SJB) along circuit CDC30 (BU/GY).

When the gear selector is placed in a position other than PARK, the key release interlock actuator (part of the ignition switch assembly) prevents the key from being removed from the ignition switch. The key release interlock actuator receives fused battery voltage from SJB fuse 27 (20A) along circuit SBP27 (BU/RD). Ground for the actuator is provided along circuit CDC41 (WH/13N), through the park detection switch (part of the gear selector assembly) and then along circuit GD112 (13 K/GN). When the gear selector lever is placed in a position other than PARK, the park detection switch closes and connects circuit CDC41 (WH/13N) to circuit GD112 (BK/GN), this grounds the key release actuator and prevents the key from being removed from the ignition switch.
^ B1352 Ignition Key-In Circuit Failure - When the battery voltage is between 10 volts and 15.5 volts and the ignition switch is in the RUN position, if the ignition key is removed from the ignition switch or if there is an open in circuit CDC30 (BU/GY), DTC B1352 will be set.

This pinpoint test is intended to diagnose the following:
^ Wiring, terminals or connectors
^ Ignition switch
^ Park detection switch (part of the gear selector lever)
^ SJB
