Inspect all harness connections that are related to the CDL and CAN Link. Make sure that the connectors are clean and tight.
Check the connectors for proper mating. Ensure that all the seals are present and in place.
Check the harness for signs of damage or abrasion.
Check the wires at the connector. Ensure that the wires are secured tightly into the connector. Take care not to pull the wire out of the connector.
Check the exposed wires at the connectors for nicks or signs of abrasion.
Check for moisture inside the connector.
Check the connectors for dirty contacts or corroded contacts.
Check each pin and each socket of the machine harness connectors. Ensure that the contacts are properly installed. The contacts should mate correctly when the two pieces of the connector are placed together. Expected Result:The machine harness connectors are tight and free of corrosion. Results:
OK - The machine harness connectors are tight and free of corrosion. For CAN Link companion codes, proceed to Test Step 5. For CDL companion codes, proceed to Test Step 2.
NOT OK - The machine harness connectors are in need of repair.Repair: Repair the machine harness and/or the connector or replace the machine harness and/or the connector. STOPTest Step 2. CHECK FOR SHORTS TO GROUND IN THE CAT DATA LINK.
The key start switch and disconnect switch remain in the OFF position.
Disconnect the machine and cabinet harness from all electronic control modules that use the CDL.
At the cabinet harness for the MCM, measure the resistance between contacts 8 (wire 893-GN) and the cabinet ground. Measure the resistance between contacts 9 (wire 892-BR) of the CDL and the cabinet ground.Expected Result:The resistance is greater than 5000 Ohms.Results:
OK - The resistance is greater than 5000 Ohms. The harness circuit resistance is correct. Proceed to Test Step 3.
NOT OK - The resistance is less than 5000 Ohms. The machine harness has failed. Repair: There is a short between frame ground and the CDL circuit in the machine harness. Repair the machine harness or replace the machine harness. STOPTest Step 3. CHECK THE MACHINE HARNESS FOR A SHORT TO THE +BATTERY CIRCUIT.
