COMMENTS ON TROUBLE SYMPTOM
If  the  audio  sound  is  not  output,  the  radio  and  CD
changer,  audio  amplifier,  or  power  supply  circuit  of
audio  amplifier  may  have  a  problem,  or  the  option
coding information may be inconsistent.

PROBABLE CAUSES

Malfunctions of radio and CD changer

Malfunction of audio amplifier

Option coding information inconsistency

Damaged harness wires and connectors

DIAGNOSIS

Required Special Tools:

MB991223: Harness Set

MB992006: Extra Fine Probe

MB991958: Scan Tool (M.U.T.-III Sub Assembly)

MB991824: Vehicle Communication Interface (V.C.I.)

MB991827: M.U.T.-III USB Cable

MB991910: M.U.T.-III Main Harness A

STEP 1. Check the ETACS-ECU coding data.

(1)

Operate the scan tool MB991958 to read the ETACS-ECU
option  coding  information.  (Refer  to  GROUP  00,  Coding
Table P.00-34.)

(2)

Check that the "Speaker" is set to "Premium."

Q:Is the check result normal?

YES:

 Go to Step 2.

NO:

 Operate scan tool MB991958 to set the option coding

"Speaker" to "Premium," and check the trouble symptom.

DIAGNOSIS

STEP 2. Check audio amplifier connector D-126 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

Q:Is audio amplifier connector D-126 in good condition?

YES:

 Go to Step 3.

NO:

 Repair or replace the damaged component(s). Refer to

GROUP 00E, Harness Connector Inspection P.00E-2.

STEP 3. Check the ground circuit to the rear monitor.
Measure the resistance at audio amplifier connector D-126.

(1)

Disconnect audio amplifier connector D-126, and measure
the  resistance  available  at  the  wiring  harness  side  of  the
connector.

ZC5010410041

Harness side: D-126

(2)

Measure the resistance between terminal 24 and ground.

OK: The resistance should be 2 ohms or less

ZC5010410042

Harness side: D-126

(3)

Measure the resistance between terminal 31 and ground.

OK: The resistance should be 2 ohms or less

ZC5010410043

Harness side: D-126

(4)

Measure the resistance between terminal 32 and ground.

OK: The resistance should be 2 ohms or less

Q:Is the measured resistance 2 ohms or less?

YES:

 Go to Step 5.

NO:

 Go to Step 4.

STEP 4. Check the wiring harness between audio amplifier
connector D-126 (terminal 24, 31, 32) and ground.

Check the ground wires for open circuit.

Q:Is the wiring harness between audio amplifier connector

D-126 (terminal 24, 31, 32) and ground in good condition?

AUDIO AND NAVIGATION SYSTEM

DIAGNOSIS

YES:

 The trouble can be an intermittent malfunction

(Refer to GROUP 00, How to use Troubleshooting/inspection
Service Points, How to Cope with Intermittent
Malfunction P.00-15).

NO:

 The wiring harness may be damaged or the connector

(s) may have loose, corroded or damaged terminals, or
terminals pushed back in the connector. Repair the wiring
harness as necessary.

STEP 5. Check the power supply circuit to the ETACS-ECU.
Measure the voltage at audio amplifier connector D-126.

(1)

Disconnect audio amplifier connector D-126, and measure
the voltage available at the wiring harness-side connector.

ZC5010400045

Harness side: D-126

(2)

Measure the voltage between terminal 25 and ground.

OK: The voltage should measure approximately 12
volts (battery positive voltage).

ZC5010400046

Harness side: D-126

(3)

Measure the voltage between terminal 35 and ground.

OK: The voltage should measure approximately 12
volts (battery positive voltage).

ZC5010400047

Harness side: D-126

(4)

Measure the voltage between terminal 36 and ground.

OK: The voltage should measure approximately 12
volts (battery positive voltage).

Q:Is the measured voltage approximately 12 volts (battery

positive voltage)?

YES:

 Go to Step 7.

NO:

 Go to Step 6.

STEP 6. Check the wiring harness between audio amplifier
connector D-126 (terminal 25, 35, 36) and fusible link (36).

Check the power supply line for open circuit and short circuit.

Q:Is the wiring harness between audio amplifier connector

D-126 (terminal 25, 35, 36) and fusible link (36) in good

condition?

YES:

 Go to Step 7.

AUDIO AND NAVIGATION SYSTEM

54B-27

DIAGNOSIS

NO:

 The wiring harness may be damaged or the connector

(s) may have loose, corroded or damaged terminals, or
terminals pushed back in the connector. Repair the wiring
harness as necessary.

STEP 7. Check radio and CD changer connector C-14 and
audio amplifier connector C-127 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.

Q:Are  radio  and  CD  changer  connector  C-14  and  audio

amplifier C-127 in good condition?

YES:

 Go to Step 8.

NO:

 Repair or replace the damaged component(s). Refer to

GROUP 00E, Harness Connector Inspection P.00E-2.

STEP 8. Check the wiring harness between radio and CD
changer connector C-14 (terminal 17) and audio amplifier
connector D-127 (terminal 3)

NOTE: 

Also check intermediate connector C-22 for loose,

corroded, or damaged terminals, or terminals pushed back in
the connector. If intermediate connector C-22 is damaged,
repair or replace the connector as described in GROUP 00E,
Harness Connector Inspection P.00E-2.

Check the communication lines for open circuit.

Q:Is  the  wiring  harness  between  radio  and  CD  changer

connector  C-14  (terminal  17)  and  audio  amplifier

connector D-127 (terminal 3) in good condition?

YES:

 

Go to Step 9.

NO:

 The wiring harness may be damaged or the connector

(s) may have loose, corroded or damaged terminals, or
terminals pushed back in the connector. Repair the wiring
harness as necessary.

STEP 9. Retest the system
Replace the audio amplifier, then check that the audio sound is
output.

Q:Is the check result normal?

YES:

 The trouble can be an intermittent malfunction

(Refer to GROUP 00, How to use Troubleshooting/inspection
