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 for schematic and connector information.

Normal Operation
Fused battery voltage is provided to the ignition switch from battery junction box (BJB) fuse 1 (30A) along circuit 1050 (LG/VT). The ignition switch then provides power to the central junction box (CJB) and the lighting control module (LCM) through several different circuits depending on the ignition switch position. The ignition switch has 4 possible positions:
^ OFF - No power on any circuits
^ ACC - Power on circuit 296 (WH/VT)
^ RUN - Power on circuits:
- 296 (WH/VT)
- 1717 (VT/OG)
- 687 (GY/YE)
^ START - Power on circuits:
- 1522 (DG)
- 1717 (VT/OG)

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