Power Down During Cranking
During starting of the engine certain loads are deactivated to allow maximum voltage to be applied to the starter motor. These loads are then re-introduced over a 2-second period after the engine has started in order to limit the current draw from the battery and load on the generator.
POWER DOWN DURING CRANKING
| Order | Load | Delay after startup |
|---|---|---|
| 1 | Wipers and headlights | 0.0 sec |
| 2 | Blower motor | 0.5 sec |
| 3 | Power windows | 1.0 sec |
| 4 | Heated rear window | 1.5 sec |
| 5 | Heated front screen | 2.0 sec |
NOTE:
The power down is limited to a maximum of 45 seconds, after which time all loads are enabled. This ensures that functions are not inhibited in the event of an ignition switch malfunction or incorrect cranking signal received by the BC1.
