Nissan Pathfinder (2008 year). Manual - part 114

BRC-218

< ECU DIAGNOSIS >

[HDC/HSA/VDC/TCS/ABS]

ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)

In case of an electrical malfunction with the ABS, the ABS warning lamp, VDC OFF indicator lamp and SLIP
indicator lamp will turn on. In case of an electrical malfunction with the EBD system, the BRAKE warning lamp,
ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp will turn on.
The system will revert to one of the following conditions of the Fail-Safe function.

1.

For ABS malfunction, only the EBD is operative and the condition of the vehicle is the same condition of
vehicles without ABS/TCS/VDC system.

2.

For EBD malfunction, the EBD and ABS become inoperative, and the condition of the vehicle is the same
as the condition of vehicles without ABS/TCS/VDC or EBD system.

VDC/TCS SYSTEM

In case of TCS/VDC system malfunction, the VDC OFF indicator lamp and SLIP indicator lamp are turned on
and the condition of the vehicle is the same as the condition of vehicles without TCS/VDC system. In case of
an electrical malfunction with the TCS/VDC system, the ABS control continues to operate normally without
TCS/VDC control.

• 2: Under the following conditions, ABS is activated and vibration is felt when brake pedal is lightly depressed. 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]

Diagnosis Procedure

INFOID:0000000001691086

1.

CHECK BRAKE PEDAL STROKE

Check brake pedal stroke. Refer to 

BR-7, "Brake Pedal Inspection and Adjustment"

.

Check that there are pedal vibrations when the engine is started.

Do vibrations occur?

YES

>> GO TO 2

NO

>> Inspect the brake pedal.
