SAFETY INFORMATION SAFETY INFORMATION LUBRICANTS ) Avoid prolonged and repeated contact with petroleum-based oils. Used oil may irritate the skin, and can ...--/ cause skin cancer and other skin disorders. Wash thoroughly after working with oil. We recommend water soluble hand cleaners. Do not use kero- sene, gasoline, or any other solvent, to remove oil from your skin. If repeated or prolonged contact with oil is necessary, wear protective clothing. Soiled clothing, particu- larly those soiled with used oils and greases containing lead, should be cleaned at regular intervals. 46UGIX-002 JACKING POSITIONS Warning Improperly jacking a vehicle is dangerous. The vehicle can slip off the jack and cause serious injury. Use only the correct front and rear jacking positions and block the wheels. Use safety stands to support the vehicle after it has been lifted.

FUNDAMENTAL PROCEDURES 1. Inspection of parts When removed, each part should be carefully inspected for malfunctioning, deformation, damage, and other problems. 2. Arrangement of parts All disassembled parts should be carefully arranged for reassembly.Be sure to separate or otherwise identify the parts to be replaced from those that will be reused. 3. Cleaning parts for reuse All parts to be reused should be carefully and thoroughly cleaned in the appropriate method. Warning Using compressed air can cause dirt and other ,, particles to fly out, causing injury to the eyes. Wear protective eye wear whenever using com- pressed air. REASSEMBLY Standard values, such as torques and certain adjust- ments, must be strictly observed in the reassembly of all parts. Refer to STANDARD BOLT AND NUT TIGHTENING TORQUE in section TD for tightening torques not men- tioned in the main text. If removed, these parts should be replaced with new ones: 1. Oil seals 4. Gaskets 2. O-rings 5. Lock washers 3. Cotter pins 6. Nylon nuts Depending on location: 1. Sealant should be applied to gaskets. 2. Oil should be applied to the moving components of parts. 3. Specified oil or grease should be applied at the pre- scribed locations (such as oil seals) before reassembly. 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

GI ELECTRICAL PARTS Locking Connectors When locking connectors, listen for a click that will indi- cate they are securely locked. 4' Inspection 1. When a tester is used to check for continuity or to mea- sure voltage, insert the tester probe from the wiring har- ness side. I I 46UGIX-039 GI-I 6 2. Check the terminals of waterproof connectors from the connector side, as they cannot be accessed from the wiring harness side. Caution To prevent damage to the terminal, wrap a thin ..J wire around the lead before inserting it into the terminal. TERMINALS lnspection Pull lightly on individual wires to check that they are secured in the terminal. Replacement Use the appropriate tools to remove a terminal as shown. When installing a terminal, be sure to insert it until it locks securely. Insert a thin piece of metal from the terminal side of the connector, and then, with the terminal locking tab pressed down, pull the terminal out from the connector. b' Gartner Banana
