Diagnosis Procedure
cautionPerform 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 “B” TERMINAL CIRCUIT
  1. 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.
