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.
System States In Virgin Mode
The BES System can be set in 5 different states (OFF LOCKED is not available in virgin mode), depending on the status of the terminals and Engine status:
| System State | Terminal Status | Engine status |
|---|---|---|
| 1. OFF - UNLOCKED | OFF | Stopped |
| 2. ACC | ACC | Stopped |
| 3. IGN | IGN1, IGN2, ACC | Stopped |
| 4. Start | IGN1, START with special pattern of activation | Cranking |
| 5. IGN - Engine | IGN1, IGN2, ACC | Running (means "self-running") |
Referring to the terminals, the system states described in the table above are same as those one found in a system based on a mechanical ignition switch.
The one of distinction with Mechanical-Ignition-Switch based system is that the BES system allows specific transition from [OFF] to [START] without going through [ACC] and [IGN] states.
