1 Audio system type and symbol used.

HINT: Confirm the applicable type of audio system. (See page BE-139) .

I; Symbol for type of audio system the question applies to.

HINT: If the audio system type is not applicable, proceed to next question below.

3 Junction without black circle.

HINT: Proceed to next question below.

i Junction with black circle.

HINT: Proceed to question for applicable audio system type.

.-V HINT: Select question for applicable audio system type.

Anti-Theft System

The anti-theft system is only provided for audio systems equipped with an Acoustic Flavor function.

HINT: The words "ANTI-THEFT SYSTEM" are displayed on the cassette tape slot cover:

For operation instructions for the anti-theft system, please consult the audio system section in the Owner's

Manual.

1. SETTING SYSTEM

The system is in operation once the customer has pushed the required buttons and entered the customer-selected 3-digit I D number.

(Refer to the Owner's Manual section, "SETTING THE ANTI-THEFT SYSTEM"). HINT:

• when the audio system is shipped the ID number has not been input, so the anti-theft system is not in operation.

• If the I D number has not been input, the audio system remains the same as a normal audio system.

2. ANTI-THEFT SYSTEM OPERATION

If the normal electrical power source (connector or battery terminal) is cut off, the audio system becomes inoperable, even if the power supply resumes.

3. CANCELLING SYSTEM

The ID number chosen by the customer is input to cancel the anti=theft system. (Refer to the Owner's Manual, "IF THE SYSTEM IS ACTIVATED")

HINT: To change or cancel the ID number, please refer to the Owner's Manual, "CANCELLING THE SYSTEM".

Troubleshooting

NOTICE: When replacing the internal mechanism (computer part) of the audio system, be careful that no part of your body or clothing comes in contact with the terminals of the leads from the IC, etc. of the replacement part (spare part).

HINTS; This inspection procedure is a simple troubleshooting which should be carried out on the vehicle during system operation and was prepared on the assumption of system component troubles (except for the wires and connectors, etc.).

Always inspect the trouble taking the following items into consideration,

• Open or short circuit of the wire harness

• Connector or terminal connection fault

• For audio systems with anti-theft system, troubleshooting items marked (*) indicate that

"Troubleshooting for ANTI-THEFT SYSTEM" should be carried out first.

Parts Inspection

1. INSPECT ANTENNA MOTOR

(a) Connect the positive (+) lead from the battery to terminal

1 and the negative (-) lead to terminal 4.

(b) Check that the motor turns (moves upward). NOTICE: These tests must be performed quickly (within 3-5 seconds) to prevent the coil from burning out.

(c) Then, reverse the polarity, check that the motor turns the opposite way (moves downward). NOTICE: These tests must be performed quickly (within 3-5 seconds) to prevent the coil from burning out. If operation is not as specified, replace the motor.

2. INSPECT ANTENNA MOTOR CONTROL RELAY (Relay Circuit)

Disconnect the connector from the relay and inspect the connector on wire harness side as shown in the chart.

REMOVAL AND INSTALLATION OF ANTENNA ROD 1. REMOVE ANTENNA ROD

H I NT: Perform this operation with the battery negative (-) cable connected to the battery terminal.

(a) Turn the ignition switch to "LOCK" position.

(b) Remove the antenna nut.

nr-HfiTr

(C-1) With CD player

Press the "AM, FM" buttons on the radio receiver, and simultaneously turn the ignition switch to "ACC" position.

(C-2) Without CD player

Press the "AM" button on the radio receiver, and simultaneously turn the ignition switch to "ACC" position.

• The rod will extend fully and be released from the motor antenna.

• After removing the antenna rod, leave the ignition switch at "ACC".

NOTICE: To prevent body damage when the antenna rod is released, hold the rod while it comes out.

2. INSTALL ANTENNA ROD

(a) Insert the cable of the rod until it reaches the bottom. HINT:

• When inserting the cable, the teeth on the cable must face toward the rear of the vehicle.

(b) Wind the cable to retract the rod by turning the ignition switch to "LOCK" position. HINT:

• If the ignition switch is already in "LOCK" position, perform step 1. (c) first, then turn the ignition switch to "ACC" position.

• In case the cable is not wound, twist it as shown in the illustration.

• Even if the rod has not retracted fully, install the antenna nut and inspect the antenna rod operation. It will finally retract fully.

(c) Inspect the antenna rod operation by pushing the radio wave band select buttons.
