The ignition switch distributes fused battery voltage to the Smart Junction Box (SJB), Battery Junction Box (BJB), run/start relay and starter relay depending on the current ignition switch position. The ignition switch receives fused battery voltage from SJB fuse 27 (20A) along circuit SBP27 (BU/RD). The ignition switch has 4 positions:
- OFF - Power on circuit CDC30 (BU/GY) to the SJB for key-in ignition chime
- ACC - Power on circuit CDC33 (VT/GN)
- RUN - Power on circuits CDC32 (BN/YE), CDC33 (VT/GN) and CDC34 (WH/OG)
- START - Power on circuit CDC35 (BU/WH) and CDC34 (WH/OG)
