Diagnosis Procedure

2015 Nissan-Datsun Juke SL, 4WDSECTION Diagnosis Procedure
CAUTION:

Perform diagnosis under the condition that engine cannot start by the following procedure.

  1. Remove fuel pump fuse.
  2. Crank or start the engine (where possible) until the fuel pressure is released.

  1. CHECK FUSIBLE LINK

    Check that the following fusible link is not blown.

    Terminal No. Signal name Fusible link No.
    2 Battery power supply A (225 A)

    Is the fusible link blown?

    YES 

    Replace the blown fusible link after repairing the affected circuit if a fusible link is blown.

    NO 

    GO TO STEP 2  .

  2. CHECK "B" TERMINAL CIRCUIT

    1. Turn ignition switch OFF.
    2. Check that starter motor "B" terminal connection is clean and tight.
    3. Check voltage between starter motor "B" terminal and ground.
      FOR NISMO RS MODELS

      Terminals Voltage (Approx.)
      (+) (-)
      Starter motor "B" terminal Terminal
      E59 2 Ground Battery voltage
      EXCEPT FOR NISMO RS MODELS

      Terminals Voltage (Approx.)
      (+) (-)
      Starter motor "B" terminal Terminal
      F11 2 Ground Battery voltage

    Is the inspection result normal?

    YES 

    GO TO STEP 3  .

    NO 

    Check harness between battery and starter motor for open circuit.

  3. CHECK BATTERY CABLE CONNECTION STATUS (VOLTAGE DROP TEST)

    1. Shift selector lever to "P" or "N" position. (CVT models)

      Keep depressing clutch pedal fully. (M/T models)

    2. Check voltage between battery positive terminal and starter motor "B" terminal.
    FOR NISMO RS MODELS

    Terminals Condition Voltage (Approx.)
    (+) (-)
    Starter motor
    "B" terminal
    Terminal
    Battery positive terminal E59 2 When the ignition switch is in START position Less than
    0.5 V
    EXCEPT FOR NISMO RS MODELS

    Terminals Condition Voltage (Approx.)
    (+) (-)
    Starter motor
    "B" terminal
    Terminal
    Battery positive terminal F11 2 When the ignition switch is in START position Less than
    0.5 V

    Is the inspection result normal?

    YES 

    GO TO STEP 4  .

    NO 

    Check harness between the battery and the starter motor for poor continuity.

  4. CHECK GROUND CIRCUIT STATUS (VOLTAGE DROP TEST)

    1. Shift selector lever to "P" or "N" position. (CVT models)

      Keep depressing clutch pedal fully. (M/T models)

    2. Check voltage between starter motor case and battery negative terminal.
    Terminals Condition Voltage (Approx.)
    (+) (-)
    Starter motor case Battery negative terminal When the ignition switch is in START position Less than 0.2 V

    Is the inspection result normal?

    YES 

    "B" terminal circuit is OK. Further inspection is necessary. Refer to WORK FLOW (WITH GR8-1200 NI)  or WORK FLOW (WITHOUT GR8-1200 NI) .

    NO 

    Check the starter motor case and ground for poor continuity.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • You smell fuel, burning insulation, or see smoke.
  • Brakes feel soft, pull hard to one side, or make grinding noises.
  • The engine overheats, stalls repeatedly, or misfires under load.
  • You are missing required tools, torque specs, or safe lifting equipment.
  • You are not confident in the next step or safety outcome.
