The IBS calculates the State of Charge (SOC) and State of Health (SOH) of the battery. It communicates this data to the ECM via a Local Interconnect Network (LIN) bus or a dedicated signal wire. The ECM uses this data to regulate the alternator duty cycle, adjusting charging voltage based on the battery's needs (often referred to as "Decoupling" or "Load Dump" strategies). nissan p155b00

Before exploring Nissan-specific details, it is helpful to understand the code's general structure. The first letter, "P", stands for , indicating a fault within the engine, transmission, or associated drivetrain components. The following "1" is a generic, standardized OBD2 code, meaning it has a similar definition across many car brands. The "55" indicates the specific fault area, and the "B" is the specific fault within that area. The final "00" suggests that the code is a standard DTC without additional manufacturer-specific information.

When the Engine Control Module (ECM) detects a voltage that is outside the normal operating range, it will trigger this code. This is not to be confused with the same code on other makes, like Chevrolet or Buick, where it often refers to a cruise control switch circuit issue, highlighting the importance of proper diagnosis for your specific Nissan.

If you're a Nissan owner dealing with a P155B00 code, here are a few suggestions:

Turn the ignition on (engine off) and probe the power supply wire to the battery sensor connector to verify it receives clean voltage from the IPDM or fuse block.
