ECM INSPECTION TABLE
Specification data are reference values and are measured between each terminal and (43) (ECCS ground).




TERMINALS 1 THRU 13
*: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)




TERMINALS 14 THRU 25




TERMINALS 26 THRU 48
*: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)
**: For Non-California models




TERMINALS 49 THRU 70
*: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)
**: During the on-board diagnosis for the open circuit, approx. 1.5- 5V will appear. This is not a malfunction.




TERMINALS 101 THRU 118
*: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)
