STARTING SYSTEM DIAGNOSIS WITH 165-DSS-5000P 

To test the starting system, use the following special service tool:

• Battery and electrical diagnostic analyzer 165-DSS-5000P.

NOTE: Refer to the diagnostic analyzer instruction manual for proper starting system diagnosis procedures.

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.

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
