I've been playing the "free new battery" lottery for a while and finally got the IMA light to come on. Not sure if this would result in a new battery or $50 charge to clear the code, I read the service manual about reading the IMA codes. I talks about grounding the SCS line in the ODBII connector and the counting the IMA light flashes to get the code. Well it worked. Here's how you can do it..
0. If you don't have the service manual, don't bother. Without being able to look up the codes and see what it means, you'll just be wasting time.
1. Key off.
2. Locate the OBDII port.(honda calls it the DLC) in '00 & '01 it is in front of the center console on the passenger side.
3. Locate pin 9. In '00 & '01 models it the uppermost towards the rear. There is also a very small '9' next to it.
4. Put the end of a paper clip or similar sized wire in the hole next to it.
5. Clip a jump on that wire and to the chassis ground. The bracket the OBDII port is mounted on is good. It should look like this

6. Key on (Don't start the car, just turn it on)
7. On the dash, the IMA, EPS, ABS, SRS and CEL/MIL will all flash any stored codes. It will flash longs flashes for the Tens digit and short flashes for last digit. Pause. and repeat. (example: if your IMA light flashes Long-long-long-long-long-long-long-short-short-short-short-short-short-short then you have code 77 which is "battery module deterioration" and you could be getting a new battery.) If multiple codes are stored then it will flash out the first code, then the next code, so on and then repeat. It's not real easy to read the code(s), so after you think you have it, double check.
8. Turn the key off and remove the wires.
This will not clear any stored codes. Some subsystems (i.e. the IMA) can be cleared by disconnecting the battery or pulling fuse 18. Others require the use of a scanner. The CEL/MIL codes are not the standard P-codes, they are honda-specific numbers listed in the service manual.
Have fun.
