C1155 BRAKE FLUID LEVEL SWITCH
Description
The brake fluid level switch converts the brake fluid level to an electric signal and transmits it to the ABS actuator and electric unit (control unit).
DTC Logic
DTC DETECTION LOGIC
DTC CONFIRMATION PROCEDURE
1.CHECK SELF-DIAGNOSIS RESULTS
Check the self-diagnosis results.
Nissan-Datsun Truck Armada 2WD V8-5.6L (VK56DE) C CODE Page 60
Is above displayed on the self-diagnosis display?
YES - Proceed to diagnosis procedure. See: C1155.
NO - Inspection End
Diagnosis Procedure
Regarding Wiring Diagram information, See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Diagrams/Electrical
Diagrams.
1.CONNECTOR INSPECTION
1. Disconnect ABS actuator and electric unit (control unit) connector and brake fluid level switch connector.
2. Check the terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?
YES - GO TO 2
NO - Repair or replace as necessary.
2.CHECK HARNESS BETWEEN BRAKE FLUID LEVEL SWITCH AND ABS ACTUATOR AND ELECTRIC
UNIT (CONTROL UNIT)
1. Check continuity between ABS actuator and electric unit (control unit) connector E125 (A) terminal 8 and brake fluid level switch connector
E21 (B) terminal 1.
2. Check continuity between ABS actuator and electric unit (control unit) connector E125 (A) terminal 8 and ground.
Is the inspection result normal?
YES - GO TO 3
NO - Repair or replace malfunctioning components.
3.CHECK BRAKE FLUID LEVEL SWITCH GROUND
Check continuity between brake fluid level switch connector E21 terminal 2 and ground.
Nissan-Datsun Truck Armada 2WD V8-5.6L (VK56DE) C CODE Page 61
Is the inspection result normal?
YES - GO TO 4
NO - Repair or replace malfunctioning components.
4.CHECK BRAKE FLUID LEVEL SWITCH
Perform the brake fluid level switch component inspection. See: C1155.
Is the inspection result normal?
YES - Perform self-diagnosis again. If the same results appear, replace ABS actuator and electric unit
(control unit). See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Hydraulic Control Assembly - Antilock
Brakes/Service and Repair.
NO - Replace brake fluid level switch.
Component Inspection
1.CHECK BRAKE FLUID LEVEL SWITCH
1. Turn ignition switch OFF.
2. Disconnect brake fluid level switch connector.
3. Check continuity between brake fluid level switch terminals.
Is the inspection result normal?
YES - Inspection End
NO - Replace brake fluid level switch.
Special Repair Requirement
1.ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION
Always perform neutral position adjustment for the steering angle sensor when replacing the ABS actuator and electric unit (control unit). See:
Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Steering Angle Sensor/Testing and Inspection/Description.
- GO TO 2
2.CALIBRATION OF DECEL G SENSOR
Always perform calibration of decel G sensor when replacing the ABS actuator and electric unit (control unit). See: Brakes and Traction
Control/Antilock Brakes / Traction Control Systems/Yaw Rate Sensor/Testing and Inspection/Description.
