54B-237

COMMENTS ON TROUBLE SYMPTOM
If all the turn-signal lamps do not illuminate, the
ignition switch (IG1), the turn-signal lamp switch
input circuit or the ETACS-ECU may be defective.

POSSIBLE CAUSES

•

Malfunction of the column switch

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE

Step 1. Check that the hazard warning lamps
operate.

Check that the hazard warning lamps illuminate
normally.

Q: Is the check result normal?

YES :

Go to Step 6.

Step 2. Connector check: C-217 ETACS-ECU
connector

Q: Is the check result normal?

YES :

Go to Step 3.

NO :

Repair the defective connector.

Step 3. Measure the voltage at the C-217
ETACS-ECU connector.

(1) Remove the ETACS-ECU, and measure at the

junction block side.

(2) Voltage between C-217 ETACS-ECU connector

terminal No.11 and body earth

OK: System voltage

Q: Is the check result normal?

YES :

Go to Step 5.

NO :

Go to Step 4.

Step 4. Check the wiring harness between C-217
ETACS-ECU connector terminal No.11 and the
battery.

SYMPTOM PROCEDURES

SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR

54B-239

NOTE:

Prior to the wiring harness inspection, check
intermediate connector C-116 and junction block
connector C-202, and repair if necessary.

•

Check the power supply line for open circuit.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

−

How to

Cope with Intermittent Malfunction

P.00-6

).

NO :

Repair the wiring harness.

Step 5. Retest the system.

Check that the turn-signal lamps illuminate normally.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

−

How to

Cope with Intermittent Malfunction

P.00-6

).

NO :

Replace the ETACS-ECU.

Step 6. Pulse check

Check the input signals below, which are related to
the turn-signal lamp illumination.

OK: The MUT-II/III sounds or the voltmeter
needle fluctuates.

Q: Is the check result normal?

All the signals are received normally. :

Go to Step

7.

The turn-signal lamp switch (RH) signal is not
received. :

Refer to inspection procedure N-5 "The

column switch (lighting and turn-signal lamp
switch) signal is not received

P.54B-319

."

The turn-signal lamp switch (LH) signal is not
received. :

Refer to inspection procedure N-5 "The

column switch (lighting and turn-signal lamp
switch) signal is not received

P.54B-319

."

Step 7. Retest the system.

Check that the turn-signal lamps illuminate.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

−

How to

Cope with Intermittent Malfunction

P.00-6

).

NO :

Replace the ETACS-ECU.

54B-240

INSPECTION PROCEDURE K-2: The hazard warning lamps do not illuminate.

CAUTION

Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM
If the hazard warning lamps do not illuminate, the
hazard warning lamp input signal circuit or the
ETACS-ECU may be defective.

POSSIBLE CAUSES

•

Malfunction of the hazard warning lamp switch

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors
