B26F2 on Infiniti
Ignition Relay Stuck ON (manufacturer-specific)
B26F2 on Infiniti vehicles indicates ignition relay stuck on (manufacturer-specific). Au7o has documented this code across 1 Infiniti model — most commonly on QX60. B26F2 is a manufacturer-specific body code, documented on Nissan/Infiniti vehicles as the ignition relay being stuck in the ON position. The relay (typically inside the IPDM power-distribution module) supplies power to ignition circuits, and the module sets this code when it detects the relay contacts remaining closed when they should open. It can lead to circuits remaining powered and potential battery drain or no-crank/no-start anomalies. Typical repair costs on Infiniti range from $200 to $1,200, depending on the specific model and root cause.
Common Causes of B26F2
- •Stuck ignition relay inside the IPDM/power distribution module
- •Failed IPDM (intelligent power distribution module)
- •Wiring short keeping the relay energized
- •Corroded connector at the IPDM
- •BCM/IPDM communication or control fault
- •Internal module driver failure

Infiniti QX60(1 issue)
- Battery Drain / No-Start from Telematics, Infotainment, or Control Module Sleep Issues2022-2025
Owners of the redesigned QX60 have reported dead batteries, repeated jump-starts, and no-start conditions after the vehicle sits overnight or for a few days. Complaints and forum reports point to parasitic draw from modules that do not go to sleep properly, including telematics and infotainment-related systems, rather than a simple worn battery in many low-mileage cases. The problem is especially frustrating because battery replacement alone may not permanently fix it.
