Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Pinpoint Test Bi: Ignition Status Run/Start Input Concern: Notes
Normal Operation and Fault Conditions
The BECAME provides battery voltage to the RCM and, if equipped, PAD indicator (vehicles without center stack display only). The BECAME compares HS-CAN1 messages to ignition voltage inputs. If the status of the HS-CAN1 message and the voltage input do not match, the BECAME sets a DTC.
If a fault is detected, the BECAME stores the appropriate DTC in memory and sends a message to the RCM over HS-CAN1 and HS-CAN2, indicating that a BECAME fault is present. Upon receipt of this message, the RCM sets DTC U0413:92 and sends a message to the IPC to illuminate the airbag warning indicator.
