G I INSTALLATION OF MOBILE TWO-WAY RADIO SYSTEMIAUDIO ANTITHEFT SYSTEM INSTALLATION OF MOBILE TWO-WAY RADIO SYSTEM If a mobile two-way radio system is installed improperly or if a high-powered type is used, the CIS and other systems may be affected. L-.) When the vehicle is to be equipped with a mobile two-way radio, observe the following precautions: 1. lnstall the antenna at the farthest point from control units. 2. Install the antenna feeder as far as possible from the control unit harnesses (at least 30 cm (11.8 in)). 3. Ensure that the antenna and feeder are properly adjusted. 4. Do not install a hiah-h owe red mobile two-wav radio svstem. FEEDER W!RE CONTROL UNIT HARNESS AT LEAST 30 cm (11.8 in) 46UGIX-043 AUDIO ANTITHEFT SYSTEM An audio with an antitheft function is optionally available. Before removing the negative battery terminal or discon- necting the audio power source, obtain the code number and deactivate the audio antitheft system. (Refer to section T.) Gartner Banana

AUDIO T I Symptom: Poor sound quality or noise (Radio) 1 ,, Possible cause Damaged cassette tape Damaged speaker Damaged antenna Damaged audio unit Open circuit in wiring harness Poor connection of connector 45UOTX-245 Step 1 1. Tune to the strongest AM station using the automatic memory function. 2. If the automatic memory function does not operate, go to Step 4. 3. Compare sound quality with that of another vehicle that has the same type audio unit. 4. If the sound quality is inferior to the other unit, go to Step n L. 5. If the sound quality is the same as the other unit, the sys- tem is OK. Step 2 1. Play a known good cassette tape, and compare the sound quality with another vehicle that has the same type audio unit. 2. If the sound quality is inferior to the other unit, the mal- function may be in the speaker circuit. Go to Step 3. 3. If the sound quality is same as the other unit, the mal- function may be in the antenna circuit. Go to Step 4. Step 3 1. Check for damage to the speakers. 2. Check for proper connection of speaker connectors. 3. Disconnect the speaker connectors, and measure resis- tance of each speaker. Resistance: 452 4. If a speaker has incorrect resistance or is damaged, re- place it. 5. If the speakers are OK, replace the audio unit. Step 4 1. Check that there is no continuity (infinite ohms) between the mast antenna and a body ground. 2. If there is continuity, replace the antenna. 3. If there is no continuity, go to Step 5.

T AUDIO / SNAP-RING OUN TlNG NUT BROKEN Antenna Mast Removal / Installation 1. Using snap-ring pliers, remove the mounting nut. 2. With the ignition switch at ACC or ON, turn the radio switch on, and pull out the antenna mast. Check the end of the plastic rack for damage. If the rack end is kinked or broken, replace the motor. 3. With the ignition switch at ACC or ON and the radio on, feed the rack of the new mast into the motor with toothed side facing toward the front of the vehicle. Turn the radio off. While the motor is retracting the rack, feed the mast into the motor. 4. Reinstall the mounting nut. 5. With the ignition switch at ACC or ON, turn the radio on and off a few times and check to see that the antenna op- erates smoothly. Gartner Banana
