Normal Operation And Fault Conditions The ignition switch receives fused battery voltage from the BCM fuse 18 (5A). In the ACC or ON position, this voltage is sent through the ignition switch and back to the BCM. In the START position, this voltage is sent through the ignition switch and then to both the BCM and the PCM. BCM DTC FAULT TRIGGER CONDITIONS DTC Description Fault Trigger Conditions U300A:01 Ignition Switch: General Electrical Failure The BCM continuously monitors the ignition switch position. This DTC sets if the voltage inputs to the BCM do not match the pre-defined configurations for each ignition switch position. Possible Causes Fuse Wiring, terminals or connectors Ignition switch Visual Inspection And Diagnostic Pre-Checks Inspect the battery and battery cables. Inspect the high current BJB fuse 2 (125A). Inspect the BCM fuse 18 (5A). PINPOINT TEST A: NO POWER IN ALL IGNITION SWITCH POSITIONS - CONVENTIONAL IGNITION SWITCH A1 CHECK THE IGNITION SWITCH Ignition OFF. Disconnect Ignition Switch C250.
