First diagnose P1554 NISSAN code
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals.
Cost of diagnosing the P1554 NISSAN code
Labor: 1.0The cost of diagnosing the P1554 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the P1554 NISSAN code detected?The P1554 code is detected when the output voltage of the battery current sensor is lower than the specified value while the battery voltage is high enough.
P1554 NISSAN Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1554 NISSAN MeaningThe power generation voltage variable control enables fuel consumption to be decreased by reducing the engine load which is caused by the power generation of the generator. The battery current sensor is installed to the battery cable at the negative terminal. The sensor measures the charging/discharging current of the battery. Based on the sensor signal, the Engine Control Module (ECM) judges whether or not the power generation voltage variable control is performed. When performing the power generation voltage variable control, ECM calculates the target power generation voltage based on the sensor signal. And ECM sends the calculated value as the power generation command value to IPDM E/R.
