ECM
Tech Tips
The standard voltage and resistance of each ECM terminal is shown in the table below.
In the table, first follow the information under "Condition". Look under "Terminal No. (Symbol)" for the terminals to be inspected. The standard voltage or resistance between the terminals is shown under "Specified Condition".
Use the illustration above as a reference for the ECM terminals.
