| - | The little grey box above the main fuse is a relay that deactivates the motor controller in case the driver's door is opened or the tank lid is open. The relay is controlled by a circuit located in the rear distribution box, that also drives a warning beeper. This immobilizer function is required by ECE R-100 (only for the "open tank lid" case) to avoid that the car is moved while the charger cable is still connected. See also the similar requirement [[astra_conv:conversion:conversion#sound indicates state of operation|]]. With the current setup, both conditions will trigger both beeper and immobilizer. | + | The little grey box above the main fuse is a relay that deactivates the motor controller in case the driver's door is opened, the tank lid is open or an isolation fault of the traction circuit against the chassis was detected.

| - | Room for improvement: The immobilizer should not be allowed to engage any more once the car is moving. This would avoid the dangers of the car just stopping on the road just because of a broken door contact or a malfunction of the tank lid position sensor. | ||
