U1000, U1002 CAN COMM CIRCUIT
DescriptionINFOID:0000000003766990
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

PRECAUTIONS
Precaution for Brake Control
INFOID:0000000003767032
 When starting engine or when starting vehicle just after starting engine, brake pedal may vibrate or motor
operating noise may be heard from engine compartment. This is normal condition.
 When an error is indicated by ABS or another warning lamp, collect all necessary information from customer
(what symptoms are present under what conditions) and check for estimate causes before starting diagnos-
tic servicing. Besides electrical system inspection, check brake booster operation, brake fluid level, and oil
leaks.
 If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
 ABS might be out of order or malfunctions by putting a radio (wiring inclusive), an antenna and a lead-in wire
near the control unit.
 If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.
 VDC system may not operate normally or a VDC OFF indicator lamp or SLIP indicator lamp may light.
- When replacing the following parts with parts other than genuine parts or making modifications: Suspension
related parts (shock absorber, spring, bushing, etc.), tires, wheels (other than specified sizes), brake-related
parts (pad, rotor, caliper, etc.), engine-related parts (muffler, ECM, etc.) and body reinforcement-related parts
(roll bar, tower bar, etc.).
- When driving with worn or deteriorated suspension, tires and brake-related parts.
Precautions for Harness RepairINFOID:0000000003843440
COMMUNICATION LINE
 Solder the repaired area and wrap tape around the soldered area.
NOTE:
A fray of twisted lines must be within 110 mm (4.33 in).
 Bypass connection is never allowed at the repaired area.
NOTE:
Bypass connection may cause communication error as spliced
wires that are separate from the main line or twisted lines lose
noise immunity.
 Replace the applicable harness as an assembly if error is detected
on the shield lines of communication line.

 To remove brake tube, use a flare nut wrench to prevent flare nuts and brake tube from being dam-
aged. To install, use flare nut crowfoot and torque wrench.
 Do not apply excessive impact to ABS actuator and electric unit (control unit), such as dropping it.
 Do not remove and install actuator by holding harness.
 After work is completed, bleed air from brake tube. Refer to BR-10, "
Bleeding Brake System".
 After installing harness connector in the ABS actuator and electric unit (control unit), make sure
connector is securely locked.
 When replacing ABS actuator and electric unit (control unit), make sure to adjust neutral position of
steering angle sensor. Refer to BRC-66, "
ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL
POSITION : Description".
Install ABS actuator and electric unit (control unit) as per the follow-
ing steps.
1. Temporarily tighten mounting bolt (1) because the bracket (2) is
temporarily being hold.
2. Tighten mounting bolt (3) while holding the bracket.
3. Tighten mounting bolts to the specified torque in the order of (4),
(1).
