In 2003 I experienced a cold starting problem. When near -
20 C or below, my Honda Insight 2000 was starting rather strangely. At that
temperature, it is not the hybrid motor that starts the gas engine but the
12V starter. And this is normal. There was the sound of a relay buzzing and
then the starter is engaged. Here is an example video:

Note that the key was turned once and kept turned all the time of the video.
When the temperature is higher, the IMA is starting the gas engine and all
was OK then.The IMA Indicator light came On. The problems given by the
ODBII tool were: P1600 IMA System Malfunction, P1586 MPI (Motor Power
Inverter) problem, 58 Charge/Discharge Circuit problem, P1580 Battery
Current Circuit problem, P1635 BCM Module problem
The problem was two corroded ground cables from the transmission and
engine to the body. They broke by the engine vibration because they where
oxidized.
The cables where replaced in December 2003. 6 months later, as I was
