Trouble Diagnoses
Symptom Possible causes Repair order
Radio inoperative (no digital
display and no sound from
speakers).1. 10A fuse
2. Poor radio case ground
3. Radio1. Check 10A fuse (No.
18, located in fuse block). Turn igni-
tion switch ON and verify battery positive voltage is present
at terminal
V10of radio.
2. Check radio case ground.
3. Remove radio for repair.
Radio controls are operational,
but no sound is heard from
any speaker.1. Radio output
2. Radio1. Check radio output voltages.
2. Remove radio for repair.
Radio presets are lost when
ignition switch is turned OFF.1. 7.5A fuse
2. Radio1. Check 7.5A fuse (No.
6, located in fuse block) and verify
battery positive voltage is present at terminal
V6of radio.
2. Remove radio for repair.
Individual speaker is noisy or
inoperative.1. Speaker
2. Radio output
3. Speaker circuit
4. Radio1. Check speaker.
2. Check radio output voltages.
3. Check wires for open or short between radio and speaker.
4. Remove radio for repair.
Radio stations are weak or
noisy.1. Antenna
2. Poor radio ground
3. Radio1. Check antenna.
2. Check radio ground.
3. Remove radio for repair.
Radio generates static noise
with engine running.1. Poor radio ground
2. Loose or missing ground bonding straps
3. Ignition condenser or rear window defogger
noise suppressor condenser
4. Alternator
5. Ignition coil or secondary wiring
6. Radio1. Check radio ground.
2. Check ground bonding straps.
3. Replace ignition condenser or rear window defogger noise
suppressor condenser.
4. Check alternator.
5. Check ignition coil and secondary wiring.
6. Remove radio for repair.
Radio generates static noise
with accessories on (switch
pops and motor noise).1. Poor radio ground
2. Antenna
3. Accessory ground
4. Faulty accessory1. Check radio ground.
2. Check antenna.
3. Check accessory ground.
4. Replace accessory.
SPEAKER INSPECTION
1. Disconnect speaker harness connector.
2. Measure the resistance between speaker terminals
V1andV2.
lThe resistance should be2-4W.
3. Using jumper wires, momentarily connect a 9V battery between speaker terminals
V1andV2.
lA momentary hum or pop should be heard.
ANTENNA INSPECTION
Using a jumper wire, clip an auxiliary ground between antenna and body.
lIf reception improves, check antenna ground (at body surface).
lIf reception does not improve, check main feeder cable for short circuit or open circuit.
RADIO INSPECTION
All voltage inspections are made with:
lIgnition switch ON or ACC
lRadio ON
lRadio connected (If removed for inspection, supply a ground to the case using a jumper wire.)

CATS (Code) System/For Europe RHD
NOTE:
lThis system is used for code indicator-equipped radios on all models.
lThe Europe LHD model with KA24E engine has a NATS-linked anti-theft function with radio as
optional equipment that renders the code system inoperable.
DESCRIPTION
By using a personal 4-digit code known only to the vehicle owner, the possibility of the audio unit being sto-
len is effectively reduced, because without the code the unit can not be activated. When in normal use, the
unit is unlocked and accessible in the usual way.
If however, someone attempts to remove the unit or the battery cable is disconnected, the anti-theft system
activates and the unit ``locks''. The only way it can be unlocked is by entering a personal code number known
only by the owner.
UNLOCKING THE UNIT (How to enter a personal code number)
lIf the battery supply to the vehicle is interrupted by accident for some reason, the unit will lock.
To unlock the unit, proceed as follows:
1. Press the power/volume control knob to turn the unit on.
2. ``CODE IN'' is displayed.
3. Input your personal code by pressing the preset buttons (1 to 4).
4. Press the
button.
5. If the entered code number is correct, the radio turns on.
When the code is incorrect
1. If the entered code is incorrect, the unit becomes inoperable for 10 seconds for the first three attempts,
then the code input mode is automatically set (``CODE IN'' is displayed).
2. If the code is incorrect the fourth time, the unit becomes inoperable for 60 minutes and ``
'' is dis-
played. After 60 minutes, the code input mode is automatically set (``CODE IN'' is displayed).
NOTE:
If the above is repeated 17 times, the unit will lock and ``LOCKED'' is displayed.
3. After ``LOCKED'' is displayed, radio can be returned to the code input mode only within three attempts
as follows. (Only three attempts are allowed to unlock the unit.)
a. Press the power/volume control knob while pushing both the MOD and TA switches.
b. The unit then returns to the code input mode.
CAUTION:
If the third attempt is unsuccessful, the unit will lock permanently.
