Mechanics Guide Step-by-step diagnosis

Step-by-Step Diagnostic Procedure

  1. Use Bobcat Service Analyzer to confirm P0087 active vs. historical, note rail pressure target vs. actual.

  2. Replace primary fuel filter (400 hr interval) and water separator; drain any water.

  3. Run SCV command test in Service Analyzer -- rail pressure should climb to ~160 MPa.

  4. Check lift pump pressure at filter -- should be 15-30 psi at idle.

  5. If SCV and filters are good and rail pressure still low, test HP pump volumetric output.
