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 con-
secutively, the ETACS-ECU sets the DTC B16A5.

.

TROUBLESHOOTING HINTS

• The wiring harness or connectors may have

loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector

• Malfunction of the ETACS-ECU

DIAGNOSIS

Required Special Tools:

• MB992006: Extra fine probe

• MB991223: Harness set

• 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 (Vehicles with

CAN communication system)

STEP 1. Check headlight assembly (RH) connector A-57
<front>, side turn-signal light (RH) connector A-02 <side>,
rear combination light (RH) connector F-06 <rear> for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Are headlight assembly (RH) connector A-57 <front>,

side turn-signal light (RH) connector A-02 <side>, rear
combination light (RH) connector F-06 <rear> in good
condition?
YES : Go to Step 2.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

.

STEP 2. Check ETACS-ECU connectors C-304 and C-311
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Are ETACS-ECU connectors C-304 <front or side> and

C-311 <rear> 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 wiring harness between headlight
assembly (RH) connector A-57 (terminal 3) <front>, side
turn-signal light (RH) connector A-02 (terminal 2) <side>,
rear combination light (RH) connector F-06 (terminal 2)
<rear> and ETACS-ECU connector C-304 (terminal 16)
<front or side> or C-311 (terminal 19) <rear>.
NOTE: Also check intermediate connector D-11 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector D-11 is damaged, repair or
replace the connector as described in GROUP 00E, Harness
Connector Inspection

P.00E-2

.

• Check the communication line for open circuit.

Q: Are the wiring harness between headlight assembly

(RH) connector A-57 (terminal 3) <front>, side
turn-signal light (RH) connector A-02 (terminal 2)
<side>, rear combination light (RH) connector F-06
(terminal 2) <rear> and ETACS-ECU connector C-304
(terminal 16) <front or side> or C-311 (terminal 19)
<rear> in good condition?
YES : Go to Step 4.
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 4. Using scan tool MB991958, Check whether the
diagnostic trouble code is reset.

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958. Refer to "How to connect

scan tool

P.54A-105

."

(2) Turn the ignition switch to the "ON" position.
(3) Erase the DTC.
(4) Turn the ignition switch from "LOCK" (OFF) position to "ON"

position.

(5) Check if DTC is set.
Q: Is the DTC set?

YES : Replace the ETACS-ECU.
NO : The procedure is complete.

DTC L0432: RLS RS Adaptation Error

.

TROUBLE JUDGMENT

When the lighting control sensor is installed with the
wrong procedure, DTC L0432 is stored by LIN.

.

TECHNICAL DESCRIPTION (COMMENT)

The lighting control sensor may have been installed
with the wrong procedure.

• Incorrect installation procedure: Connect the con-

nector before mounting the lighting control sensor
onto the optical coupler of the windshield.

• Correct installation procedure: Mount the lighting

control sensor onto the optical coupler of the
windshield. Wipe the windshield surface thor-
oughly, and check that the surface is dry. Then,
connect the connector.

.

TROUBLESHOOTING HINTS

• Lighting control sensor improperly installed

• Lighting control sensor (rain sensor) abnormal

operation

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

• MB991910: M.U.T.-III Main Harness A (Vehicles with

CAN communication system)

STEP 1. Using scan tool MB991958, Check whether the
diagnostic trouble code is reset.
Disconnect the connector from the lighting control sensor, and
connect the connector to the lighting control sensor again.
Then, check again if the DTC is set to LIN.

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958. Refer to "How to connect

scan tool

P.54A-105

."

(2) Disconnect the connector of lighting control sensor, and

connect it again.
NOTE: When connecting the connector, follow the correct
installation procedure.

(3) Turn the ignition switch from "LOCK" (OFF) position to "ON"

position.

(4) Check if DTC is set.
Q: Is the DTC set?

YES : Go to Step 2.
NO : The lighting control sensor is installed with the wrong

procedure.
