Hello, I'm looking for information about the OBD-II diagnostic codes P1601 and P1435 that appear on my 2003 Honda Civic. Could anyone please explain what these codes mean and their potential causes? Thank you for your help. Alice
I may be incorrect, but on my Honda Accord hybrid, these codes relate to the IMA (Integrated Motor Assist) system. - P1601: IMA System Malfunction - P1435: Charge/Discharge Balance Malfunction Does your 2003 Honda Civic have a hybrid powertrain? If so, this could be relevant.

If so, this could be relevant. Yes, that's correct — both codes apply to hybrid vehicles. For accurate diagnosis and repair of these issues, access to the Motor Control Module (MCM) for the IMA system is required. Only certified Honda hybrid technicians should perform repairs due to the risk of personal injury or death from high-voltage components.
