No. 190 CD-player fails to work when activating

Malfunction Cause

Solution

Power source circuit
malfunction or fuse
damaged;

Inspect +B and GND, which normal value shall be 10V to 14V. When ACC
and GND ignition switch locating at ACC or ON, the voltage shall be 10V to
14V. In common condition, GND and vehicle earth lead shall be conducted. If
it indicates no powers supply, then check whether the fuse is burnt or not,
and replace it if necessary.

CD-player power switch
malfunction or damage

①

Check the power switch on CD panel; operate the power switch by hand, if

there is no response then replace the CD-player

CD-player fails to
work when
activating

Internal CD-player power
source circuit
malfunction

④

Check the voltage of internal CD-player power source end, if the value is

between 10~14V as normal, then replace the CD-player assembly

No. 191 CD-player keeps soundless under all modes

Malfunction Cause

Solution

①

CD-player power

source malfunction

Inspect +B and GND, which normal value shall be 10V to 14V. When ACC and
GND ignition switch locating at ACC or ON, the voltage shall be 10V to 14V. If it
indicates no powers supply, then shall confirm whether the fuse is burnt or not,
and replace it if necessary.

②

Loudspeaker

malfunction

Check whether the appearance of loudspeaker is damaged, as well as the coil
whether it is burnt.
Method: Measure the resistance by multimeter setting at ohms range, and the
value shall be 4 Ohm, if it indicates to infinite, then the loudspeaker is burnt and
need to be replaced.

③

Wires and

connector

Check loudspeaker and CD-player connection whether there is open/short
circuit. Measure two ends of same colour respectively by multimeter setting to
Ohms range, and the value shall be 0 which means conducted. Check
CD-player rear plug whether it is loose, and the power source voltage whether
it is normal. In generally condition, GND and body earthlead shall be
conducted.

CD-player keeps
soundless under all
modes

④

CD-player sound

controller damaged

Check whether CD-player sound controller is damaged, and track adjustment
whether it is correct, as well as sound adjusting variable voltage regulator
whether it is badly worn. Replace CD-player assembly.

No. 192 CD-player/radio gains no power

Malfunction Cause

Solution

①

Vehicle ignition switch closed

①

Turn ignition device to ON or ACC position

②

Fuse burnt

②

Replace fuse of same specification

③

Power source output line loose

③

Replace it with new connector of same

specification if abnormal

④

Dirt in connector conducting point.

④

Clean the conducting point with special cleaning

solution or replace it with a new one.

⑤

Connector wire core disconnected

(open circuit)

⑤

Check loudspeaker output line with multimeter

whether it is disconnected, replace it with new
connector of same specification if necessary

⑥

Poor fuse contact (open circuit

sometimes)

⑥

Connect vehicle battery earthlead and speaker

housing by lead wire, if CD-player regains normal
operation, which indicates the earth lead open
circuit, then replace it with new connector of same
specification.

No. 193 A loudspeaker of CD-player/radio is soundless

Malfunction Cause

Solution

Panel function setting inaptitude

In SEL menu, on panel, BAL and FDA shall be set to 0

Loudspeaker damaged

Replace loudspeaker of same specification. (Note: Firstly,
connect the output line of front right loudspeaker to the other
one, and check the sound output, which can indicate whether
the loudspeaker is broken.)

Loudspeaker output line wrong
connected

Check output line connection whether it is correct. (Please
refer to the connecting method shows on nameplate.)

Connector conducting point and
output line connection containing
dirt or oxide.

Clean the connector with special cleaning solution or replace
it with a new one of same specification.

Connector wire core disconnected
(open circuit)

Measure loudspeaker output line by multimeter, whether it is
disconnected. And replace it with a new one of same
specification when necessary.
