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 

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

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

   Without CONSULT 

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

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