Work Flow
STEPDESCRIPTION
STEP 1 Get detailed information about the conditions and the environment when the incident occurred. The following are key pieces of information required to make a good analysis:
WHATVehicle Model, Engine, Transmission and the System (i.e. Radio).
WHEN Date, Time of Day, Weather Conditions, Frequency.
WHERE Road Conditions, Altitude and Traffic Situation.
HOW System Symptoms, Operating Conditions (Other Components Interaction).
Service History and if any After Market Accessories have been installed.
STEP 2 Operate the system, road test if necessary. Verify the parameter of the incident.
If the problem cannot be duplicated, refer to ªIncident Simulation Testsº next page.
STEP 3 Get the proper diagnosis materials together including: POWER SUPPLY ROUTING
System Operation Descriptions
Applicable Service Manual Sections
Check for any Service Bulletin.
Identify where to begin diagnosis based upon your knowledge of the system operation and the customer comments.
STEP 4 Inspect the system for mechanical binding, loose connectors or wiring damage. Determine which circuits and components are involved and diagnose using the Power Supply Routing and Harness
Layouts.
STEP 5 Repair or replace the incident circuit or component.
STEP 6 Operate the system in all modes. Verify the system works properly under all conditions. Make sure you have not inad- vertently created a new incident during your diagnosis or repair steps.

IDo not disconnect pump harness connector with engine
running.
I Do not disassemble electronic fuel injection pump.
If NG, take proper action.
I Do not disassemble injection nozzle.
If NG, replace injection nozzle.
I Even a slight leak in the air intake system can cause seri-
ous problems.
I Do not shock or jar the crankshaft position sensor (TDC).
I Do not depress accelerator pedal when starting.
I Immediately after starting, do not rev up engine unneces-
sarily.
I Do not rev up engine just prior to shutdown.
I When installing C.B. ham radio or a mobile phone, be sure
to observe the following as it may adversely affect elec-
tronic control systems depending on its installation loca-
tion.
1) Keep the antenna as far as possible away from the ECM.
2) Keep the antenna feeder line more than 20 cm (7.9 in) away from the harness of electronic controls.
Do not let them run parallel for a long distance.
3) Adjust the antenna and feeder line so that the standing- wave ratio can be kept smaller.
4) Be sure to ground the radio to vehicle body.

NATS AUDIO LINK
Description
The link with the NATS IMMU implies that the audio unit can basically only be operated if connected to the
matching NATS IMMU to which the audio unit was initially fitted on the production line.
Since radio operation is impossible after the link with the NATS is disrupted, the stolen audio unit is basically
useless since special equipment is required to reset the audio unit.
Initialization process for audio units that are linked to the NATS IMMU
New audio units will be delivered to the factories in the ªNEWº state, i.e. ready to be linked with the vehicle's
NATS. When the audio unit in ªNEWº state is first switched on at the factory, it will start up communication
with the vehicle's immobiliser control unit (IMMU) and send a code (the ªaudio unit Codeº) to the IMMU. The
IMMU will then store this code, which is unique to each audio unit, in its (permanent) memory.
Upon receipt of the code by the IMMU, the NATS will confirm correct receipt of the audio unit code to the audio
unit. Hereafter, the audio unit will operate as normal.
During the initialization process, ªNEWº is displayed on the audio unit display. Normally though, communica-
tion between audio unit and IMMU takes such a short time that the audio unit seems to switch on directly
without showing ªNEWº on its display.
Normal operation
Each time the audio unit is switched on afterwards, the audio unit code will be verified between the audio unit
and the NATS before the audio unit becomes operational. During the code verification process, ªWAITº is
shown on the audio unit display. Again, the communication takes such a short time that the audio unit seems
to switch on directly without showing ªWAITº on its display.
When the radio is locked
In case of a audio unit being linked with the vehicle's NATS (immobiliser system), disconnection of the link
between the audio unit and the IMMU will cause the audio unit to switch into the lock (ªSECUREº) mode in
which the audio unit is fully inoperative. Hence, repair of the audio unit is basically impossible, unless the audio
unit is reset to the ªNEWº state for which special decoding equipment is required.
Clarion has provided their authorized service representatives with so called ªdecoder boxesº which can bring
the audio unit back to the ªNEWº state, enabling the audio unit to be switched on after which repair can be
carried out. Subsequently, when the repaired audio unit is delivered to the final user again, it will be in the
ªNEWº state as to enable re-linking the audio unit to the vehicle's immobiliser system. As a result of the above,
repair of the audio unit can only be done by an authorized Clarion representative.

Service instruction
ItemRadio linked with IMMU and/or SECU
Battery disconnection No additional action required
Radio needs repair Repair needs to be done by authorised representative of radio manufacturer since radio cannot be operated unless it is reset to NEW state, using special decoding equipment
Replacement of radio by new part Radio is delivered in NEW state. If possible, the radio will automatically link up with the immobiliser system. If this appears not possible, CATS code needs to be manually input
Transferring radio to another vehicle/
replacement of radio by an ªoldº part Radio needs to be reset to NEW state by authorised representative of radio manufac-
turer
Replacement of IMMU by new part Radio will request for CATS code input prior to establishing the link with the IMMU
Replacement of IMMU by old part If a radio code has already been stored in memory of the IMMU, the radio cannot be linked to it. After switching on the radio, it will display ªSECUREº after 1 minute. Opera-
tion can only be established after resetting the ratio by an authorised representative of
radio manufacturer
CATS code input procedure
1. Radio displays ªCODE INº after the power is switched ON.
2. Enter CATS code (4-digits) by pressing the preset buttons (using 1 to 4).Press the preset buttons for the necessary amount of times for the number of each digits.
e.g. CATS code is ª5432º
Press No. 1 preset button for 5 times
Press No. 2 preset button for 4 times
Press No. 3 preset button for 3 times
Press No. 4 preset button for 2 times
3. Press the
button.
4. If the code is OK, the radio will power ON. If the code is NG, the radio will be locked up as below. After the lock up, the radio will display ªCODE INº
again.
1st to 3rd attempt: The radio will be locked for 10 seconds after each attempt
4th to 20th attempt: The radio will be locked for 60 minutes after each attempt
Over 20th attempt: The radio will be locked completely
SPEED DEPENDENT VOLUME CONTROL
Description
If activated, the radio output volume will be automatically adjusted to compensate for increased driving noises
at higher driving speeds. The radio receives a speed signal from the combination meter and selects the out-
put volume.

IDiscs with a large outside diameter. [Normal size is 120 mm (4.72 in).]
I Discs with rough or lipped edges.
I Discs with excessive thickness [Normal size is 1.2 mm (0.047 in).]
I Discs with scratches, abrasions, or pits on the surface.
I Discs with grease/oil, fingerprints, foreign material.
I Discs are warped due to excessive heat exposure.
3. Slide/place the discs in and out of the various magazine positions. Identify any discs and/or positions that require additional force for placement/ejection. If interference
(sticking, excessive tensions) is found, replace the magazine or the discs.
Note:
I Discs which are marginally out of specification (ex. dirty, scratched and so on) may play correctly
on a home stereo.
However, when used in the automative environment skipping may occur due to the added vehicle
movement and/or vibration due to road conditions. Autochangers should not be replaced when
discs are at fault.
I Use a soft damp cloth to wipe the discs starting from the center outward in radial direction. Never
use chemical cleaning solutions to clean the discs.
