Schematic of the Transmission Shift LeverThis diagnostic code is recorded when the Machine ECM does not receive expected information from the shift lever for a period of more than three seconds. The activation of the FMI 09 diagnostic code will neutralize the transmission.Test Step 1. INSPECT THE HARNESS CONNECTIONS.
Turn the disconnect switch to the OFF position.
Inspect all harness connections that are related to the Cat Data Link. Make sure that the connectors are clean and that the connectors are tight.
Check the connectors for proper mating. Ensure that all the seals are present and that all seals are 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. Proceed to Test Step 2.
NOT OK - The machine harness connectors are in need of repair.Repair: Repair the machine harness or replace the machine harness. STOPTest Step 2. CHECK FOR SHORTS TO GROUND
The disconnect switch remains in the OFF position.
Disconnect the machine harness connectors from all electronic control modules that use the Cat Data Link.
At the machine harness for the shift lever, measure the resistance between frame ground and connector contacts 3 (wire 893-GN) and
