Test A: No Power in All Ignition Switch Positions

Pinpoint Test A: No Power In All Ignition Switch Positions
Refer to Vehicle/Diagrams, Power Distribution/SJB for schematic and connector information.

Normal Operation
The ignition switch receives fused battery voltage along circuit SBP27 (BU/RD) from smart junction box (SJB) fuse 27 (20A). The ignition switch then sends that voltage out to various systems depending on ignition switch position. The ignition switch has 4 possible states:
^ OFF - No power on any circuits
^ ACC - Power on circuit CDC33 (VT/GN)
^ RUN - Power on circuits CDC33 (VT/GN) and CDC34 (WH/OG)
^ START - Power on circuit CDC34 (WH/OG), CDC35 (BU/WH) and CE619 (BU/BN) (non-hybrid vehicles)

This pinpoint test is intended to diagnose the following:
^ Fuse
^ Wiring, terminals or connectors
^ Ignition switch
^ SJB
