Mitsubishi Outlander XL. Manual — part 987

｠

If there is a malfunction to the right turn-signal light
bulb, the blown right bulb counter counts once when
the illumination of hazard or turn-signal light (right
side) is attempted.

｠

If the blown right bulb counter reaches "3," the DTC
B16A4 is set.

｠

Malfunction of turn-signal light bulb (right side)

｠

Malfunction of the ETACS-ECU

DIAGNOSIS

Required Special Tools:

｠

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

｠

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

｠

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

｠

CAN communication system)

STEP 1. Bulb check.
Check whether the bulb of turn-signal light which does not
illuminate is normal.

Q:Is the check result normal?

YES:

Go to Step 2.

NO:

Replace the bulb of turn-signal light which does not

illuminate.

STEP 2. Using scan tool MB991958, Check whether the
diagnostic trouble code is reset.

TROUBLE JUDGMENT
When the right wiring harness of turn-signal light is
short circuited, the ETACS-ECU sets DTC B16A5.

TECHNICAL DESCRIPTION (COMMENT)
When the short circuit is detected three times
consecutively, the ETACS-ECU sets the DTC B16A5.

STEP 1. Check headlight assembly (RH) connector A-56
<front>, side turn-signal light (LH) connector A-60 <side>,
rear combination light (LH) connector D-09 <rear> for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

Q:Are headlight assembly (RH) connector A-56 <front>,

side turn-signal light (RH) connector A-60 <side>, rear

combination light (LH) connector D-09 <rear> in good

condition?

YES:

Go to Step 2.

NO:

Repair the damaged parts.

STEP 2. Resistance measurement at headlight assembly
(RH) connector A-56 <front>, side turn-signal light (RH)
connector A-60 <side>, and rear combination light (RH)
connector D-09 <rear>.

(1)

Disconnect the connector, and measure at the wiring harness
side.

(2)

Measure the resistance between the connector terminal of
light which does not illuminate and body ground.

｠

Measure the resistance between the headlight assembly
(RH) connector A-56 (terminal No. 8) and body ground.
<Front>

｠

Measure the resistance between the side turn-signal light
(RH) connector A-60 (terminal No. 1) and body ground.
<side>

｠

Measure the resistance between the rear combination light
(RH) connector D-09 (terminal No. 4) and body ground.
<Rear>

The measured value should be continuity exists (2
Ω or less).

Q:Does the measured resistance value correspond with this

range?

YES:

Go to Step 4.

NO:

Go to Step 3.

STEP 3. Check the wiring harness between headlight
assembly (RH) connector A-56 (terminal No. 8) <front>, side
turn-signal light (RH) connector A-60 (terminal No. 1)
<side>, rear combination light (LH) connector D-09
(terminal No. 4) <rear> and ground.

Q:Are the wiring harness between headlight assembly (RH)

connector A-56 (terminal No. 8) <front>, side turn-signal

light (RH) connector A-60 (terminal No. 1) <side>, rear

combination light (RH) connector D-09 (terminal No. 4)

<rear> and ground in good condition?

YES:

Go to Step 6.

NO:

Repair the wiring harness.

STEP 4. Check ETACS-ECU connectors C-304 and C-310 for
loose, corroded or damaged terminals, or terminals pushed
back in the connector.

Q:Are ETACS-ECU connectors C-304 and C-310 in good

condition?
