Hi All
Car is 2006 Civic Hybrid-2 (CVT).
110,000 miles, but I have only just bought it and it has a few niggles.
Basically, the car will flick on the IMA light, and then shortly after go in to limp mode, and then shutdown the engine when the Rev's fall below 1000rpm (at stop).
However, I am not convinced that the IMA needs to be replaced, as I think the issue is elsewhere, possible the ECM or the 12V. Based on the error codes
Error codes OBD-2:
P060A : Internal Control Module Processor Performance
P16D5: Manufacturer Control
U0100: lost communication with ECM/PCM

Previously code
P0AE1, which I've read relates to the HV battery contactor circuit.

When I reset the codes, the car often works fine for a few days, and numerous shot trips.
I think the problems are also brought on by hot weather (40+ degrees in Australia), which I doubt the battery enjoys

I am considering the following:
1) Clean all of the terminals (for corrosion, dirt etc).
2) Moving to a larger 12V battery
But most importantly to diagnose a faulty ECM/PCM - is this pretty easy for any auto-electrician? Or is there an easy test I can do myself?
BTW - I am not keen on Honda dealerships.

Thanks

 

Your issue sounds like the one my 2006 HCH 2 just went through, and it turns out that the PCM was bad. Luckily, it fell under CA's emissions warranty, which goes up to 15 years and 150K miles. If you live in CA, or are still covered under your state's emissions regulations, I suggest you take it to your Honda dealer and get it swapped out.
