Essential Maintenance Checklist
Cooling Fan Service
The IMA fan is the only thing protecting your pack from the 110°F Phoenix ambient air. Test it regularly.
12V Battery Health
A weak 12V battery can cause phantom IMA codes and poor fuel economy. We recommend replacement every 2-3 years in AZ.
Grid Charging
Regular grid charging (balancing) can significantly extend the life of older NiMH Honda packs.
Software Updates
Ensure your vehicle has the latest Honda BCM updates which optimize charge management for heat.
Understanding the IMA Light
When the Integrated Motor Assist (IMA) light illuminates on your dashboard, it's often accompanied by a P0A7F or P1433 code. In the Phoenix desert, these codes are common as the NiMH cells begin to drift in voltage due to heat stress.
Ignoring the IMA light can eventually lead to the 12V system not charging (red battery light), which can leave you stranded.
