SYMPTOM PROCEDURES

SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR

54B-209

DIAGNOSTIC PROCEDURE

Step 1. Check the diagnosis code.

When the ignition switch is turned to the LOCK
(OFF) position, check that the ETACS-ECU does not
set the diagnosis code.

Q: Is the diagnosis code set?

YES :

Refer to diagnosis code chart

P.54B-17

.

NO :

Go to Step 2.

Step 2. Pulse check

Check the input signal from the tail lamp switch.

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

3.

The ignition switch (IG1) signal is not received. :

Refer to inspection procedure N-2 "The
ignition switch (IG1) signal is not received

P.54B-301

."

The tail lamp switch 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 3. Connector check: A-11X front-ECU
connector

Q: Is the check result normal?

YES :

Go to Step 4.

NO :

Repair the defective connector.

Step 4. Measure the voltage at A-11X front-ECU
connector.

(1) Remove the front-ECU, and measure at the relay

box side.

(2) Voltage between A-11X front-ECU connector

terminal No.7 and body earth

OK: System voltage

Q: Is the check result normal?

YES :

Go to Step 6.

NO :

Go to Step 5.

Step 5. Check the wiring harness between A-11X
front-ECU connector terminal No.7 and the
battery.

•

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 6. Retest the system.

Check that the tail 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 front-ECU.

INSPECTION PROCEDURE J-2: The low-beam headlamps do not illuminate normally.

CAUTION

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

COMMENTS ON TROUBLE SYMPTOM
If the low-beam headlamps do not illuminate, the
headlamp switch input circuit or the front-ECU may
be defective.

POSSIBLE CAUSES

•

Malfunction of the column switch

•

Malfunction of the front-ECU

•

Damaged harness wires and connectors
