STEP 2. 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
<door mirror type> in good condition?
YES : Go to Step 3.
NO : Repair the damaged parts.
STEP 3. Check the wiring harness between headlight
assembly (LH) connector A-37 (terminal No. 3), side
turn-signal light (LH) connector A-10 (terminal No. 2)
<fender>, door mirror assembly (LH) connector E-29
(terminal No. 2) <door mirror type>, rear combination light
(LH) connector D-14 (terminal No. 3) and ETACS-ECU
connector C-304 (terminal No. 9), ETACS-ECU connector
C-311 (terminal No. 18) or ETACS-ECU connector C-317
(terminal No. 4).
Check the communication line for short circuit.
NOTE: Also check intermediate connector C-127 <door mirror
type> for loose, corroded, or damaged terminals, or terminals
pushed back in the connector. If intermediate connector C-127
<door mirror type> is damaged, repair or replace the connector
as described in GROUP 00E, Harness Connector Inspection

DIAGNOSTIC FUNCTION
When the right bulb of turn-signal light is blown, the
ETACS-ECU sets DTC B16A4.
.
TECHNICAL DESCRIPTION (COMMENT)
The ETACS-ECU sets DTC B16A4 under the follow-
ing conditions.
• 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-sig-
nal light (right side) is attempted.
• If the blown right bulb counter reaches "3," the
DTC B16A4 is set.
.
TROUBLESHOOTING HINTS
• Malfunction of turn-signal light bulb (right side)
• 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 bulb of turn-signal light which does not illu-
minate 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.
