Precaution for Power Generation Variable Voltage Control SystemINFOID:0000000003776561
CAUTION:
For this model, the battery current sensor that is installed to the negative battery cable measures the
charging/discharging current of the battery and performs various engine controls. If an electrical com-
ponent is connected directly to the negative battery terminal, the current flowing through that compo-
nent will not be measured by the battery current sensor. This condition may cause a malfunction of
the engine control system and battery discharge m ay occur. Do not connect an electrical component
or ground wire directly to the battery terminal.

Harness LayoutINFOID:0000000003776571
HOW TO IDENTIFY TYPE A AND TYPE B MAIN HARNESSES
The differences between Type A and type B harnesses are minimal and mainly consist of differences in the cir-
cuit connections to the fuse block (J/B).
Determine type of harness by locating the Nissan Name Plate on the main harness This can be found on the
main harness near SMJ M31 connector above the right hand
lower side dash finisher. Find the six digit num-
ber on Nissan Name Plate If the number ends in 001, it is a Type A harness, any other number indicates a
Type B harness.
HOW TO READ HARNESS LAYOUT
The following Harness Layouts use a map style grid to help locate
connectors on the drawings:
• Main Harness, Console Sub-harness, Console Switch Sub-har-
ness and Optical Sensor Sub-harness
• Engine Room Harness and Engine Room Sub-harness
• Engine Room Harness (Passenger Compartment)
• Engine Control Harness and Engine Control Sub-harness
• Chassis Harness and Rear Sonar Sensor Sub-harness
• Body Harness, Left Front Seat Harness and Third Row Power Folding Seat Sub-harness
• Body No. 2 Harness and Right Front Seat Harness
• Room Lamp Harness, Room Lamp Sub-harness A, and Room
Lamp Sub-harness B
• Back Door Harness, Back Door LH Harness, Back Door RH Harness, Back Door No. 2 LH Harness and
Back Door No. 2 RH Harness
To use the grid reference
1. Find the desired connector number on the connector list.
2. Find the grid reference.
3. On the drawing, find the crossing of the grid reference letter column and number row.
4. Find the connector number in the crossing zone.
5. Follow the line (if used) to the connector.
