PRECAUTION
- OBSERVE HANDLING AND OPERATIONAL PRECAUTIONS Explain to the customer that when the negative terminal is disconnected from the battery, the AM/FM channel presets in the radio receiver are cleared. If necessary, make a note of the recorded channel information before the negative terminal is disconnected, then reset the information after the negative terminal is reconnected. The removal/installation of the radio receiver should be performed after all cassette tapes and audio CDs are ejected from the radio receiver. HINT: If cassette tape or audio CD cannot be ejected due to a malfunction in the radio receiver, do not attempt to remove it forcefully. Bring the vehicle to a repair plant. Fasten the earth bolt securely when the antenna cord is removed or installed. HINT: Failure to fasten the earth bolt securely causes noise when receiving radio waves. Do not touch the cone paper of the speaker.

- INSPECT MAIN SWITCH ASSY Inspect the continuity between terminals at each switch position shown in «TESTER CONNECTION AND SPECIFIED CONDITION»(ref-228804-S01038371392006041100000). TESTER CONNECTION AND SPECIFIED CONDITION Switch operation Tester connection Specified condition OFF 3 <=> 4 No continuity ON 3 <=> 4 Continuity If continuity is not as specified, replace the main switch assy, Inspect the bulb state when connecting the battery to each terminal. BATTERY CONNECTION AND SPECIFIED CONDITION Inspection item Battery connection Specified condition Indicator Battery positive terminal <=> 3 Comes on Indicator Battery negative terminal <=> 6 Comes on Illumination Battery positive terminal <=> 1 Comes on Illumination Battery negative terminal <=> 2 Comes on If operation is not as specified, check the faulty bulb. Inspect continuity of the bulb by connecting the tester (Scheme 248) If continuity exists, replace the main switch assy. If no continuity exists, replace the bulb.
- INSPECT POWER POINT SOCKET RELAY Inspect continuity between terminals according to the conditions in «TESTER CONNECTION AND SPECIFIED CONDITION»(ref-228804-S12081879432006041100000). TESTER CONNECTION AND SPECIFIED CONDITION Condition Tester connection Specified condition Always 1 <=> 2 Continuity Always 3 <=> 5 No continuity Apply B+ between terminal 1 and 2 3 <=> 5 Continuity If continuity is not as specified, replace the point socket relay.
