OBD-II Code P1562
IMA Battery Pack Module Voltage (Honda)
P1562 is a Honda IMA battery sub-code that specifically indicates the IMA battery pack's overall voltage or an individual module voltage has dropped below the minimum threshold during operation. Where P1449 is the general IMA battery deterioration code triggered by SOH decline over time, P1562 is a more acute voltage fault — the pack voltage has dropped to or below the minimum safe operating level during a specific event (typically during a high-demand acceleration or a cold start). P1562 and P1449 are frequently stored together because both are caused by the same underlying battery pack degradation, just detected via different monitoring parameters. P1562 on its own (without P1449) can sometimes indicate a single module failure that has caused an acute voltage drop rather than gradual overall SOH decline.

What Causes P1562?
- 1IMA battery module voltage below minimum during high-demand discharge event
- 2Single module acute failure causing pack voltage to drop below operating threshold
- 3Cold weather start causing temporary IMA pack voltage suppression below threshold
- 4Overall IMA battery pack deterioration (stored alongside P1449)
- 5IMA battery current sensor miscalibration causing incorrect voltage readings
Symptoms You May Notice
- IMA warning light and check engine light
- P1562 often stored alongside P1449 — same observable symptoms apply
- Possible sudden loss of IMA assist mid-drive if triggered by acute module failure
- IMA battery gauge dropping to zero rapidly during acceleration
Can You Drive with P1562? — Drive with caution
Same as P1449 — vehicle is driveable on the petrol engine alone, but Honda's IMA assist is disabled. If P1562 was triggered by a sudden module failure (rather than gradual decline), the event may have included a momentary power interruption that felt like a hesitation or stumble. Get a diagnostic to confirm whether this is gradual SOH decline or an acute module failure.
How It's Diagnosed
- 1
Honda-specific scan for P1562 and any accompanying codes — P1449 is the most common companion
- 2
IMA module voltage testing across all cells to identify if a single module failed acutely
- 3
Cold-start IMA voltage measurement to check for temperature-related voltage suppression
- 4
IMA battery current sensor calibration verification
How It's Fixed
P1562 repair follows the same path as P1449 — IMA battery pack replacement is the standard fix when the code is stored as part of general pack deterioration. If a single module acute failure is identified as the root cause, targeted module replacement may be considered, though the surrounding modules are typically of similar age. We assess the individual module condition before recommending the approach.

Frequently Asked Questions — P1562
Not necessarily. P1449 (general IMA battery deterioration) and P1562 (IMA battery voltage fault) are triggered by the same underlying pack degradation — just detected via different monitoring parameters. Having both codes stored simultaneously is very common and typically means the battery has progressed to the point where both SOH decline and voltage events are occurring. A single battery replacement resolves both.
Quite possibly, but P1562 alone warrants careful diagnosis before proceeding to replacement. It could indicate a single module acute failure, a sensor calibration issue, or genuine overall pack deterioration that hasn't yet crossed the P1449 threshold. We recommend a full module voltage test to determine the root cause before committing to a repair path.
