FRONT WIPER AND WASHER SYSTEM

FRONT WIPER AND WASHER SYSTEMPFP:28810
System DescriptionEKS0032N
WIPER OPERATION
The wiper switch is controlled by a lever built into the combination switch.
There are three wiper switch positions:

LO speed

HI speed

INT (Intermittent)
With the ignition switch in the ON or START position, power is supplied

through 20A fuse [No. 6, located in the fuse block (J/B)]

to front wiper motor terminal 2.
Low and High Speed Wiper Operation
Ground is supplied to front wiper and washer switch terminal 17 through body grounds E24 and E50.
When the wiper switch is placed in the LO position, ground is supplied

through front wiper and washer switch terminal 14

to front wiper motor terminal 3.
With power and ground supplied, the wiper motor operates at low speed.
When the wiper switch is placed in the HI position, ground is supplied

through front wiper and washer switch terminal 16

to front wiper motor terminal 5.
With power and ground supplied, the wiper motor operates at high speed.
Auto Stop Operation
With wiper switch turned OFF, wiper motor will continue to operate until wiper arms reach windshield base.
When wiper arms are not located at base of windshield with wiper switch OFF, ground is provided

from front wiper and washer switch terminal 14

to front wiper motor terminal 3, in order to continue wiper motor operation at low speed.
Ground is also supplied

through front wiper and washer switch terminal 13

to front wiper motor terminal 4

through terminal 1 of the front wiper motor terminal 1 and

through grounds E24 and E50.
When wiper arms reach base of windshield, front wiper motor terminals 2 and 4 are connected instead of ter-
minals 1 and 4. Wiper motor will then stop wiper arms at the STOP position.
Intermittent Operation
The front wiper motor operates the wiper arms one time at low speed at a set interval of approximately 1 to 13
seconds. This feature is controlled by the wiper amplifier (INT SW) combined with front wiper and washer
switch.
When the wiper switch is placed in the INT position, ground is supplied to wiper amplifier.
The desired interval time is input to wiper amplifier (INT VR) from wiper volume switch combined with front
wiper and washer switch.
Then intermittent ground is supplied

through wiper amplifier (OUTPUT) and

through front wiper and washer switch terminal 14

to front wiper motor terminal 3
The wiper motor operates at low speed at the desired interval.
WASHER OPERATION
With the ignition switch in the ON or START position, power is supplied

through 20A fuse [No. 6, located in the fuse block (J/B)]

to front washer motor terminal 1.
When the lever is pulled to the WASH position, ground is supplied

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 theft of the 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 “NEW” state, i.e. ready to be linked with the vehicle's
NATS. When the audio unit in “NEW” state is first switched on at the factory, it will start up communication with
the vehicle's immobilizer control unit (IMMU) and send a code (the “audio unit Code”) 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, “NEW” is displayed on the audio unit display. Normally though, communica-
tion between audio unit and IMMU takes such a short time (300 ms) that the audio unit seems to switch on
directly without showing “NEW” 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, “WAIT” is
shown on the audio unit display. Again, the communication takes such a short time (300 ms) that the audio
unit seems to switch on directly without showing “WAIT” on its display.
When the radio is locked
In case of a audio unit being linked with the vehicle's NATS (immobilizer system), disconnection of the link
between the audio unit and the IMMU will cause the audio unit to switch into the lock (“SECURE”) 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 “NEW” state for which special decoding equipment is required.
Clarion has provided their authorized service representatives with so called “decoder boxes” which can bring
the audio unit back to the “NEW” state, enabling the audio unit to be switched on after which repair can be car-
ried out. Subsequently, when the repaired audio unit is delivered to the final user again, it will be in the “NEW”
state to enable re-linking the audio unit to the vehicle's immobilizer system. As a result of the above, repair of
the audio unit can only be done by an authorized Clarion representative (when the owner of the vehicle
requests repair and can show personal identification).
