TROUBLE JUDGMENT

When the left bulb of turn-signal light is blown, the 
ETACS-ECU sets DTC B16A2.

.

TECHNICAL DESCRIPTION (COMMENT)

The ETACS-ECU sets DTC B16A2 under the follow-
ing conditions.

• If there is a malfunction to the left turn-signal light 

bulb, the blown left bulb counter counts once 
when the illumination of hazard or turn-signal 
light (left side) is attempted.

• After the bulb counter reaches "3," DTC B16A2 is 

set.

.

TROUBLESHOOTING HINTS

• Malfunction of turn-signal light bulb (left)

• Malfunction of the ETACS-ECU

• The wiring harness or connectors may have 

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

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. Bulb check.
Check whether the left turn-signal light illuminates normally.
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. Check headlight assembly (LH) connector A-37, 
side turn-signal light (LH) connector A-10 <fender type>, 
door mirror assembly (LH) connector E-29 <door mirror 
type>, rear combination light (LH) connector D-14 for 
loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
Q: Are headlight assembly (LH) connector A-37, side 

turn-signal light (LH) connector A-10 <fender type>, 
door mirror assembly (LH) connector E-29 <door mirror 
type>, rear combination light (LH) connector D-14 in 
good condition?
YES : 
Go to Step 3.
NO  :  Repair the damaged parts.

STEP 3. Resistance measurement at headlight assembly 
(LH) connector A-37, side turn-signal light (LH) connector 
A-10 <fender type>, door mirror assembly (LH) connector 
E-29 <door mirror type>, rear combination light (LH) 
connector D-14.
(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 ground.

Measure the resistance between the headlight assem-
bly (LH) connector A-37 (terminal No. 6) and body 
ground.

Measure the resistance between side turn-signal light 
(LH) connector A-10 (terminal No. 1) and body ground. 
<fender type>

Measure the resistance between door mirror assembly 
(LH) connector E-29 (terminal No. 10) and body ground. 
<door mirror type>

Measure the resistance between rear combination light 
(LH) connector D-14 (terminal No. 4) and body ground.

The measured value should be 2 

Ω or less.

Q: Does the measured resistance value correspond with 

this range?
YES : 
Go to Step 5.
NO :  Go to Step 4.

STEP 4. Check the wiring harness between headlight 
assembly (LH) connector A-37 (terminal No. 6), side 
turn-signal light (LH) connector A-10 (terminal No. 1) 
<fender type>, door mirror assembly (LH) connector E-29 
(terminal No. 10) <door mirror type>, rear combination 
light (LH) connector D-14 (terminal No. 4) and ground.
Check the ground wires for open circuit.
NOTE: Also check intermediate connector C-126 <door mirror 
type> for loose, corroded, or damaged terminals, or terminals 
pushed back in the connector. If intermediate connector C-126 
<door mirror type> is damaged, repair or replace the connector 
as described in GROUP 00E, Harness Connector Inspection 

P.00E-2

.

Q: Are the wiring harness between headlight assembly 

(LH) connector A-37 (terminal No. 6), side turn-signal 
light (LH) connector A-10 (terminal No. 1) <fender type>, 
door mirror assembly (LH) connector E-29 (terminal No. 
10) <door mirror type>, rear combination light (LH) 
connector D-14 (terminal No. 4) and ground in good 
condition?
YES : 
Go to Step 7.
NO :  Repair the wiring harness.

STEP 5. Check ETACS-ECU connectors C-304, C-311 and 
C-317 <door mirror type> for loose, corroded or damaged 
terminals, or terminals pushed back in the connector.
Q: Are ETACS-ECU connectors C-304, C-311 and C-317 in 

good condition?
YES : 
Go to Step 6.
NO :  Repair the damaged parts.
