Yesterday my 2002 Insight displayed the IMA light and check engine light. I had no assist or regen. I turned off the car and restarted it. The IMA light was off, but the check engine light was still on and everything functioned normally. This same exact thing happened last October. I took it into the dealer today and they found a 1581 (?) code saying high amp draw. It was the same code from last October. Honda told them last time they did not know what caused it and to just reset it and see if it comes back. Well it did. They wanted to keep the car and call Honda tech, which they said could take a while, but I couldn’t afford to not have a car today, so they left the check engine light code and told me to make an appointment when I can leave the car.

Anyone else have a code like this show up?

Not exactly, Silver threw # 541 and 611 which Honda said correspond to "IMA battery voltage faults".

There were other codes as well (DTC 77 & 78, P1447, 23A, P1164) so eventually Silver received a replacement IMA battery, BCM-MCM computers and LAF O2 sensor. Little Papaya suffered in silence; no codes were retrieved to explain a month of relentless stalling during Autostop but a new IMA battery and BCM-MCMs were installed and the problem went away. This was nearly 18 months ago and so far so good.

Others on the forum are pros at reading codes but I'm not. I didn't look up the 1581 code in Search, but it might be worth a try. Best of luck. Hope all is resolved soon.

Took my 2002 into the dealer for the day to check why my IMA light keeps coming on. It's come on about 5 times in the past 2 weeks, but goes off after I turned the car off and on. All assist still works fine.

Tech just called and said it is a problem with the (and I know I have this wrong - it was on the phone) UPhase, VPhase and ZPhase sensors. They are giving a wrong reading, so he wants to replace them. Before I dropped off the car I told them if they needed to order parts to put the car back together until the parts come, so that's what they will be doing.

One other thing. The tech said he wanted to make sure it was the problem since my car is out of warruntee and all. And I said woa there, I have 63,000 miles on it. The IMA is good until 80,000. He says, Really? Well that's good then. Boy, they don't even know there own warruntee terms.
