Hello,

2000 Honda Insight here (MT/AC). Long story short charged the battery back up and it seems to be doing alright, even turns my car on. User before me cut two wires, and I’d like to return the car to stock config.Help identify please? In case I have to bypass again I’ll use switches. They appear to be a white and a green wire.

Just hook those two back up again.
Green to green.
White to white.

They are not required for bypass.

For bypass simply unhook all
connectors that go to the BCM. (Computer on top of the pack on the left)

The car is currently bypassed, so if those wires don’t bypass it, how is my battery getting charged up? Been driving it for a year or so now? Maybe the connector is slightly unplugged and I just haven’t noticed?

Thanks Eric. Let me check it out. Just finished replacing my ground straps for 2nd time. Also got sick of using my starter and replaced it as well, so figured might as well see if she works!

Perhaps @Natalya will chime in. When I had my blue Insight I learned that it had been determined by someone somewhere that one (or was it two?) wires could be cut to allow the car to operate better. It was above my pay grade but it seemed right. Cut them on mine, it performed fine without a battery, then once I installed IMA it still performed perfectly.

After pulling the negative battery wire off, how long does it take driving around for the IMA battery to show a charge? I know it’s charged for a fact, so it should show something on the gauge right? Is there a delay?

^ If you're talking about pulling the 12V neg cable to reset stuff, and having installed or otherwise 'un-bypassed' the IMA pack, then it shouldn't take much time at all. Sometimes you don't even have to drive, the BAT gauge will repopulate with just the key ON II... So, the answer is, you should see the BAT gauge lighted bars almost immediately, certainly once you start the car.

The WHT/GRN wire controls toggling into DCDC low power mode (~12.2V vs. ~13.85V). With it cut it won't go to 12.2V. The GRN/BLK wire controls whether the Motor Control Module computer can disable the DCDC. With it cut it cannot disable the DCDC. The former mod is usually done to keep the 12V battery charged higher on average. The latter mod doesn't really help much and should be reserved for special circumstances.

Good to know. I’ll hook both back up and see if it gives me any issues.

Reconnect the green/black wire but leave the white/green wire unconnected for a slightly better charged 12v battery.

Even in stock form cutting the white/green wire is sensible.

As Peter said, just hook up the green and black wire. Leave white/green wire cut. All Insight owners (whether IMA is bypassed or not) should cut the white/green wire.

More reading and a video:

Hello,

The car was starting with the electric motor vs the electric starter before after I had it charged up via grid charger. (A week passes, replaced all new grounds and power cables, and fixed cut wire per recommendation) It tried to start up with electric motor (whirling noise) but went to backup after a few seconds (carhad been sitting for a bit so it took some time. The ima battery level gauge still shows nothing (after taking a full charge a week or so ago) and I’m getting this code. Would this result in it not showing my battery level?

That code stops the IMA working so the car can't force charge when running and do a positive recalibration to determine the SOC and fill the bars on the gauge.

If the IMA battery voltage is high enough ~170V+ or above at switch on then it might do a positive calibration without the engine running if the ign is left on for a few minutes.
