TERMINALS OF ECM
HINT:
Each ECM terminal's standard voltage is shown in the table below.
In the table, first follow the information under ºConditionº. Next look under ºSymbols (Terminal No.)º for the
terminals to be inspected. The standard voltage between the terminals is shown under ºSpecific Conditionº.
Use the illustration above as a reference for the ECM terminals.
