Nissan Maxima Service and Repair Manual / Power outlet / Charging system / Power generation voltage variable control system operation inspection

Diagnosis Procedure

CAUTION: When performing this inspection, always use a charged battery that has completed the battery inspection.

(When the charging rate of the battery is low, the response speed of the voltage change will become slow. This can cause an incorrect inspection.)

1.CHECK ECM (CONSULT)

Perform ECM self-diagnosis with CONSULT.

2.CHECK OPERATION OF POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM

  1. Connect CONSULT and start the engine.
  2. The selector lever is in "P" or "N" position and all of the electric loads and A/C, etc. are turned OFF.
  3. Select "ALTERNATOR DUTY" in "Active Test" of "ENGINE", and then check the value of "BATTERY VOLT" monitor when DUTY value of "ALTERNATOR DUTY" is set to 40.0 %.

"BATTERY VOLT" 2 seconds after setting the DUTY value of "ALTERNATOR DUTY" to 40.0 % : 12 - 13.6 V

  1. Check the value of "BATTERY VOLT" monitor when DUTY value of "ALTERNATOR DUTY" is set to 80.0%.

"BATTERY VOLT" 20 seconds after setting the DUTY value of "ALTERNATOR DUTY" to 80.0 % : +0.5 V or more against the value of "BATTERY VOLT" monitor when DUTY value is 40.0 %

3.CHECK IPDM E/R (CONSULT)

Perform IPDM E/R self-diagnosis with CONSULT
