Diagnosis Procedure

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

2. Crank or start the engine (where possible) until the fuel pressure is released.
1.CHECK "S" CONNECTOR CIRCUIT

  

  1. Turn ignition switch OFF.
  2. Disconnect starter motor connector F28.
  3. Shift CVT selector lever to "P" or "N" position. (CVT models) Press and hold the clutch pedal fully with the control lever in neutral. (M/T models)
  4. Check voltage between starter motor harness connector F28 terminal S and ground with the ignition in START.

  

Is battery voltage present?
YES >> "S" circuit is OK. Further Inspection necessary. Refer to See: Initial Inspection and Diagnostic Overview.
NO >> GO TO 2
2.CHECK CONNECTOR

  1. Turn ignition switch OFF.
  2. Check the following terminals and connectors for damage, bent pins and loose connections.
    • IPDM E/R harness connector F10
    • Starter motor harness connector F28 Is the Inspection result normal?

YES >> GO TO 3
NO >> Repair the terminal and connector.
3.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

  

  1. Disconnect the following harness connectors.
  1. Check continuity between starter motor harness connector F28 terminal S and IPDM E/R harness connector F10 terminal 80.

S - 80 Continuity exists

Is there proper continuity between the two pins?
