OK - Proceed to Test Step 3.
Not OK - The measurement is 114 Ohms to 126 Ohms. A terminating resistor is missing.Repair: Install the missing resistor.Refer to the Schematic in order to determine the location of the missing resistor.Proceed to Test Step 3.
Not OK - Resistance is less than 50 Ohms. Proceed to Test Step 3.
Not OK - Resistance is greater than 130 Ohms. Proceed to Test Step 4.Test Step 3. Check the Terminating ResistorsVerify that only two terminating resistors exist on the data link. One resistor should be located on each end of the data link.For additional information, refer to the Installation Guide, "Component Installation". In addition, refer to the Schematic for your particular engine.Expected Result:One terminating resistor is correctly installed at each end of the data link.Results:
OK - The terminating resistors are installed correctly. Proceed to Test Step 4.
Not OK - The terminating resistors are not installed correctly.Repair: Correctly install the terminating resistors. Verify that the repair eliminates the original problem.STOPTest Step 4. Check the Data Link for a Short in the Harness
Turn the keyswitch to the OFF position.
