Nissan Maxima Service and Repair Manual: 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
- Connect CONSULT and start the engine.
- The selector lever is in "P" or "N" position and all of the electric loads and A/C, etc. are turned OFF.
- 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
- 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
4.CHECK HARNESS BETWEEN GENERATOR AND IPDM E/R
- Turn ignition switch OFF.
- Disconnect generator connector and IPDM E/R connector.
- Check continuity between generator harness connector F7 (A) terminal 4 and IPDM E/R harness connector F10 (B) terminal 76.
- Check continuity between generator harness connector F7 (A) terminal 4 and ground.

B2557 vehicle speed
Description
BCM receives the 2 vehicle speed signals via CAN
communication. One signal is transmitted by the "combination
meter". Another signal is transmitted by "ABS actuator and electric unit
(control unit)". BCM compares
both signals to detect the vehicle speed.

Front and Rear Sonar System (if so equipped)
The sonar (parking sensor) system sounds a tone
to inform the driver of obstacles near the bumper.
When the "DISPLAY" key is ON, the sonar view
will automatically appear in the meter.
WARNING

convenience but it is not a substitute for
proper p ...
Key cylinder switch
Description
The main power window and door lock/unlock switch detects
condition of the door key cylinder switch and
transmits to BCM as the LOCK or UNLOCK signal.
