GI HOW TO USE THIS MANUAL HOW TO USE THlS MANUAL ADVISORY MESSAGES You'll find several Warnings, Cautions, and Notes in this manual. Warning A Warning indicates a situation in which serious injury or death could result if the warning is ignored. Caution A Caution indicates a situation in which damage to the vehicle could result if the caution is ignored. Note A Note provides added information that will help you to complete a particular procedure. PREPARATION This points out the needed SSTs for the service operation. It is best to gather all necessary SSTs before beginning work. Example: 46UGIX-013 REPAIR PROCEDURE MANUAL STEERING PREPARATION SST NUMBER USAGE SST 1 1 Most repair operations begin with an overview illustration. It identifies the components, shows how the parts fit together, and describes visual part inspection. If a damaged or worn part is found, repair or replace it as necessary. Expendable parts, tightening torques, and symbols for oil, grease, and sealant are shown in the over- view illustration. Pages related to service procedures are shown under the illustration. Refer to this information when servicing the related part. 46UGIX-014 I id' I SST NAME SST ILLUSTRATION For removal of t~e rod end 49 01 18 850C Puller, ball pnt 49 01 18 850C For removal of t~e rod end Gartner Banana

ELECTRICAL PARTS GI BATTERY CABLE Before disconnecting connectors or removing electrical parts, disconnect the negative battery cable. CONNECTORS Data Link Connector Insert the probe into the service hole when connecting a jumper wire to the data link connector. Caution Inserting a jumper wire probe into the data link connector terminal may damage the terminal. Power Connector The special power connector in the engine compartment (Blue: 1 -pin) supplies battery positive voltage for exter- nally powered test equipment. Caution Do not ground the power connector terminal; the 20A wiper fuse will be burned. Disconnecting Connectors When disconnecting two connectors, grasp the connec- tors, not the wires. Connectors can be disconnected by pressing or pulling the lock lever as shown. Gartner Banana
