how to start with starter 12v

[thekanuk]

HI

The cold weather is coming soon here un North East.

I want to test my starter 12v before the real cold night.

But i not sure how.

I read somwhere here how to start with 12 v starter.

take off de fuse 2 in dashboard or turn off the breaker ima backward.

Thanks

Just turn the IMA battery off.

And, remember that there is a short delay, maybe 2-3 seconds, before the
12v starter kick in.

for the fuse 2 in dash board is it for pump gas .

If you read here in the last line InsightCentral.net - Encyclopedia - Honda Insight Engine Start-Restarting Mode

i make a mistake.

if i turn off braker battery what is suppose to hapen and what was the consequence and afther the starter test when i turn on the breaker on what happen.

My car is in perfect condition i want only be sure the starter work great.

it is the second time i start the insight with the 12v starter without no modification (no take off fuse or no turn off breaker,nothing to do).

ordinary when i start the car i put the key in the ignition ,i turn the key in position 2 and wait a few second until the dash light turn on ,ready to turn at position 3 and the motor start with the ima motor .

for start the car or exercise your 12v starter you insert the key in the ignition at position 0 and dont wait for the other position and turn quickly at position 3
"et voila" the motor start on the 12v starter with the horrible sound of the starter 12 volts.

i experiment this with the temperature under the frozen point maybe at ambient temp is not working i let you try to confirm this eureka.

Interesting. I just tried it 4 times at air temp @ 65F. Still starts on IMA.
Need someone to try in colder temperatures.

For very cold or very high ambient temperatures, does the IMA system revert to the 12V battery in lieu of the 144V pack?

If the pack PTC strip is faked with a resistor value, would this do the trick?

You can put the key in and turn it directly to start, it doesn't start off the 12v starter. No waiting needed, I crank my key quickly to start every time.

If you stall the engine while the IMA is trying to spin it up you might get a 12v start. I accidentally released the clutch once after the IMA started the spinup but before it had a chance to get it going fast enough and the next time I turned the key it started off the 12v. That only happened once for me so I'm not sure if it is repeatable but you could give it a shot.
The manual says to switch off the IMA pack with the service switch in the pack.

The car uses the 12v battery when it is -10f/-20c from what someone told me, although I've had it start off the 12v battery when it was slightly warmer than that but it's always been below -0f. I think the threshold is -20c. I'm unaware of a hot threshold, never happened to me, even when I've had the battery pack so hot that it would only give 4 bars of regen when using the brakes with plenty of headroom for charging on the SOC display and I still had auto-stop.

Yes

No

The PTC strip is only used for serious cell overheat fault detection not ambient temp detection.

My 2000 Insight had the 12V starter operating at -10C yesterday on first start of the day as measured via obdiicc gauge.
To inadvertently obtain 12V starter activation, I've bobbled the key on>off>on again, turning the engine over inititally with the IMA, but so quickly turned 'off' as not to fire, and on turning to start position very quickly following [quarter sec est.] to bump it over it reverted to 12V in warmer >0C conditions some time ago.
iirc from reading, the latter situation of a 'non-start' is sensed as a fault of the IMA not successfully generating ignition after an attempt so the starting system reverts to the backup.
I have not noticed if SoC bears into the threshold for 12V starter activation, but I've gotten it at 3bars showing at about the same temps, and also a few days previous with about 18 bars on the display.
