< ECU DIAGNOSIS INFORMATION >

[WITHOUT 7 INCH DISPLAY]

ECM

: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

*1: This may vary depending on internal resistance of the tester.

*2: Before measuring the terminal voltage, confirm that the battery is fully charged. Refer to 

PG-3, "How to Handle Battery"
