Component Function Check

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM-ENGINE CONTROL SYSTEM- ".

1. PRECONDITIONING

   TESTING CONDITION: 

   • Before performing the following procedure, confirm that battery voltage is more than 12.8 V at idle. 
   • Before performing the following procedure, confirm that all load switches and A/C switch are turned OFF. 

     GO TO  2.

2. PERFORM COMPONENT FUNCTION CHECK

   With CONSULT-III 

   1. Start engine and let it idle.
   2. Select "BAT CUR SEN" in "DATA MONITOR" mode with CONSULT-III.
   3. Check "BAT CUR SEN" indication for 10 seconds.

      "BAT CUR SEN" should be above 2, 300 mV at least once. 

   Without CONSULT-III 

   1. Start engine and let it idle.
   2. Check voltage between ECM harness connector terminals under the following conditions.
      CONNECTOR TERMINAL VOLTAGE CHART
      
      

      ECM			Voltage (V)
      Connector	Terminal	Terminal
      	+	-
      F13	42 (Battery current sensor signal)	44 (Sensor ground)	Above 2.3 at least once

      Is the inspection result normal? 

      YES: INSPECTION END

      NO: Go to "DIAGNOSIS PROCEDURE "
