NOTE:

• To ensure a complete and thorough diagnosis, the battery, starter motor and generator test segments must be done as a set from start to finish.

• If any malfunction is found, immediately disconnect the battery cable from the negative terminal.

1. DIAGNOSIS WITH BATTERY AND ELECTRICAL DIAGNOSTIC ANALYZER 165-DSS - 5000P 
   1. Perform system test with battery and electrical diagnostic analyzer 165-DSS-5000P. For details and operating instructions, refer to diagnostic analyzer instruction manual.

   How is the test result?

   CRANKING NORMAL>>

   GO TO 3.

   LOW VOLTAGE>>

   GO TO 2.

   CHARGE BATTERY>>

   Perform the slow battery charging procedure. (Initial rate of charge is 10 A for 12 hours.) Perform battery test again. Refer to diagnostic analyzer instruction manual.

   REPLACE BATTERY>>

   Before replacing battery, clean the battery cable clamps and battery posts. Perform battery test again. Refer to diagnostic analyzer instruction manual. If second test result is "REPLACE BATTERY", then do so. Perform battery test again to confirm repair.

2. COMPARISON BETWEEN ENGINE COOLANT AND CRANKING VOLTAGE 
   1. Compare engine coolant temperature and the cranking voltage with the specifications.
      Minimum Specification of Cranking Voltage Referencing Coolant Temperature
      
      

      Engine coolant temperature [°F (°C)]	Voltage [V]
      -22 to -4 (-30 to -20)	8.6
      -2 to 14 (-19 to -10)	9.1
      16 to 32 (-9 to 0)	9.5
      More than 34 (More than 1)	9.9

   Is the voltage less than the specified value?

   YES>>

   GO TO 11.

   NO>>

   GO TO 3.

3. CHECK ENGINE START 
   1. Check engine and check that engine starts.

   Does engine start?

   YES>>

   GO TO 4.

   NO>>

   GO TO 5.

4. CHECK RETURN OF PINION GEAR 
   1. Check that pinion gear returns to original position after engine starts.

   Does pinion gear return?

   YES>>

   Starter motor is OK. Inspection End

   NO>>

   GO TO 11.

5. CHECK ENGINE SPEED WITH CRANKING 
   1. Check that engine turns while cranking.

   Does engine turn by cranking?

   YES>>

   GO TO 6.

   NO>>

   GO TO 7.

6. CHECK STARTER MOTOR TURNING WITH CRANKING 
   1. Check that starter motor runs smoothly without abnormal noise at cranking.

   Does starter motor turn normally?

   YES>>

   Check ignition/fuel system.

   NO>>

   Check engine mechanical and power train system.

7. CHECK STARTER MOTOR SPEED WITH CRANKING 
   1. Check that starter motor turns while cranking.

   Does starter motor turn at cranking?

   YES>>

   GO TO 8.

   NO>>

   GO TO 9.

8. CHECK PINION GEAR AND RING GEAR ENGAGEMENT 
   1. Check condition of pinion and ring gear engagement.

   Is inspection result normal?

   YES>>

   Check engine mechanical and power train system.

   NO>>

   Check pinion protrusion length. Refer to STARTER MOTOR : Inspection  (with PR25DD engine) or STARTER MOTOR : Inspection  (with KR20DDET engine).

9. CHECK POWER SUPPLY CIRCUIT 
   1. Check the following conditions:
      • Fuse and fusible link.
      • Charge condition, corrosion and connection condition of battery. Refer to Work Procedure .

   Are these inspection results normal?

   YES>>

   GO TO 10.

   NO>>

   Repair as needed.

10. CHECK STARTING SYSTEM WIRING 
    1. Check the following:
       • "B" terminal circuit. Refer to Diagnosis Procedure  (with PR25DD engine) or Diagnosis Procedure  (with KR20DDET engine).
       • "S" terminal circuit. Refer to Diagnosis Procedure .

    Are these inspection results normal?

    YES>>

    GO TO 11.

    NO>>

    Repair as needed.

11. CHECK MAGNETIC SWITCH OPERATION 
    1. Check magnetic switch operation. Refer to STARTER MOTOR : Inspection  (with PR25DD engine) or STARTER MOTOR : Inspection  (with KR20DDET engine).

    Does magnetic switch operate normal?

    YES>>

    GO TO 12.

    NO>>

    Replace magnetic switch or stater motor.

12. CHECK PINION TURNING 
    1. 1. Remove starter motor.
       2. Check that pinion turns smoothly by hand.

    Does pinion turn normally?

    YES>>

    Perform no-load test of starter motor. Refer to STARTER MOTOR : Inspection  (with PR25DD engine) or STARTER MOTOR : Inspection  (with KR20DDET engine).

    NO>>

    Check pinion clutch. Refer to Inspection  (with PR25DD engine) or STARTER MOTOR : Inspection  (with KR20DDET engine).
