ABS, EBD SYSTEM
If ABS malfunction electrically, ABS warning lamp will turn on. If EBD malfunction electrically, brake warning
lamp and ABS warning lamp will turn on. Simultaneously, the ABS become one of the following conditions of
the fail-safe function.

ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)
 For malfunction of ABS, only the EBD is activated and the condition of vehicle is the same condition of vehi-
cles without ABS system.
NOTE:
ABS self-diagnosis sound may be heard. That is a normal condition because a self-diagnosis for “Ignition
switch ON” and “The first starting” are being performed.
 For malfunction of EBD, EBD and ABS become inoperative, and the condition of vehicle is the same as the
condition of vehicles without ABS, EBD system.

UNEXPECTED PEDAL REACTION
UNEXPECTED PEDAL REACTION
Diagnosis ProcedureINFOID:0000000003766853
1.CHECK BRAKE PEDAL STROKE
Check brake pedal stroke. Refer to BR-6, "
Inspection and Adjustment".
Is the stroke too large?
YES >>  Bleed air from brake tube and hose. Refer to BR-10, "Bleeding Brake System".
 Check brake pedal, brake booster, and master cylinder for mount play, looseness, brake system
fluid leakage, etc.
- Brake pedal: Refer to BR-6, "
Inspection and Adjustment".
- Brake booster: Refer to BR-12, "
Inspection".
- Brake master cylinder: Refer to BR-11, "
Inspection".
NO >> GO TO 2.
2.CHECK FUNCTION
Disconnect ABS actuator and electric unit (control unit) connector to deactivate ABS. Check if braking force is
normal in this condition. Connect connector after inspection.
Is the inspection result normal?
YES >> Normal
NO >> Check brake system.

CAUTION:
The stopping distance on slippery road surfaces might be longer when the ABS is operating than
when the ABS is not operating.
1.CHECK FUNCTION
Turn the ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector to deacti-
vate ABS. In this condition, check stopping distance. After inspection, connect connector.
Is the inspection result normal?
YES >> Normal
NO >> Check brake system.

PEDAL VIBRATION OR ABS OPERATION SOUND OCCURS
Diagnosis ProcedureINFOID:0000000003766856
CAUTION:
Under the following conditions, ABS is activated and vibration is felt when brake pedal is lightly
depressed (just place a foot on it). However, this is normal.
 When shifting gears
 When driving on slippery road
 During cornering at high speed
 When passing over bumps or grooves [at approximately 50 mm (1.97 in) or more]
 When pulling away just after starting engine [at approximately 10 km/h (6 MPH) or higher]
1.SYMPTOM CHECK 1
Check that there are pedal vibrations when the engine is started.
Do vibrations occur?
YES >> GO TO 2.
NO >> Inspect the brake pedal.
2.SYMPTOM CHECK 2
Check that there are ABS operation noises when the engine is started.
Do the operation noises occur?
YES >> GO TO 3.
NO >> Perform self-diagnosis.
3.SYMPTOM CHECK 3
Check symptoms when electrical component (headlamps, etc.) switches are operated.
Do symptoms occur?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to the control unit. If there is,
move it farther away.
NO >> Normal

NORMAL OPERATING CONDITION
NORMAL OPERATING CONDITION
DescriptionINFOID:0000000003766858
Symptom Result
Slight vibrations are felt on the brake pedal and the operation noises occur, when ABS is activated.
This is a normal condi-
tion due to the ABS acti-
vation. Stopping distance is longer than that of vehicles without ABS when the vehicle drives on rough, gravel, or
snow-covered (fresh, deep snow) roads.
The brake pedal vibrates and motor operation noises occur from the engine room, after the engine starts and
just after the vehicle starts.This is a normal, and it is
caused by the ABS op-
eration check.

PRECAUTIONS
Precaution for Brake Control
INFOID:0000000003766861
 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.
Precautions for Harness RepairINFOID:0000000003859437
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.

FUNCTION DIAGNOSIS
VDC
System DiagramINFOID:0000000003766885
System DescriptionINFOID:0000000003766886
 Vehicle Dynamics Control system detects driver′s steering operation amount and brake pedal travel from
steering angle sensor and pressure sensor. Using information from yaw rate/side G sensor and wheel sen-
sor, VDC judges driving condition (conditions of under steer and over steer) to improve vehicle driving stabil-
ity by controlling brake application to 4 wheels and engine output.
 During VDC operation, it informs driver of system operation by flashing SLIP indicator lamp.
 Electrical system diagnosis by CONSULT-III is available.
