 * Initially, the contactors are powered by the full 12 V voltage. After a bit, since they are already actuated, their coil voltage can be halved without dropping off the contact, to reduce their heating.
 * Initially, the supply voltage is 12 V. Later, the DC-DC converter that keeps the 12 V battery charged is turned on, so the 12 V supply jumps up to 14 V

 Sequence:
 * The CAN Bus activity starts 25 ms after the ignition is turned on
-* At 150 ms after the ignition is turned on, A CAN message (422h, byte 1 = 1Eh) tells the battery to turn on its relays
+* At 150 ms after the ignition is turned on, A CAN message (422h, byte 1 = 1Eh (models '05 through '08) or 2Eh (model '09)) tells the battery to turn on its relays
 * Then the precharge and B- contactors (K1 and K3) are turned on, to precharge the Motor Driver capacitors. There's a spike in the current reflecting the inrush. The time constant is measured to be about 35 ms. Given that the precharge resistor is 10 ohm, we derive that the capacitors in the inverters are 3.5 mF (that's 3.5 milliFarad).
 * At 416 ms, the B+ contactor is turned on (K2) to apply the full battery voltage to the Motor Driver. There's a small step in the current, as the precharge resistor is no longer in the circuit.
