SPEED LIMITER SYSTEM TERMINALS OF ECM
CHECK ECM (for 2WW)
Tip:The standard voltage between each pair of the ECM terminals is shown in the table below. The appropriate conditions for checking each pair of the terminals are also indicated.
The result of checks should be compared with the standard voltage for that pair of terminals, and displayed in the "Specified Condition" column.
The illustration above can be used as a reference to identify the ECM terminal locations.
