Mitsubishi Outlander XL. Manual - part 1100

Q:Is the check result normal?

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:

 Replace the audio visual navigation unit.

Inspection Procedure 2: No sound is heard. <Vehicles with audio amplifier>

M15410800356USA0000010001

Before replacing the ECU, ensure that the power
supply  circuit,  the  ground  circuit  and  the
communication circuit are normal.

COMMENTS ON TROUBLE SYMPTOM
If  the  audio  sound  is  not  output,  the  audio  visual
navigation unit, 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 audio visual navigation unit

｠

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?
