SYMPTOM PROCEDURES
SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR
54B-213
INSPECTION PROCEDURE J-3: The high-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 high-beam headlamps do not illuminate, the
dimmer 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
DIAGNOSTIC PROCEDURE
Step 1. Check that the headlamps operate.
Check that the low-beam headlamps illuminate and
extinguish normally.
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Refer to inspection procedure J-2 "The
low-beam headlamps do not illuminate
normally
."
Step 2. Pulse check
Check the input signal from the dimmer switch.
OK: The MUT-II/III sounds or the voltmeter
needle fluctuates.
Q: Is the check result normal?
YES :
Go to Step 3.
NO :
Refer to inspection procedure N-5 "The
column switch (lighting and turn-signal lamp
switch) signal is not received

NO :
Replace the front-ECU.
INSPECTION PROCEDURE J-4: The high-beam and low-beam headlamps do not illuminate when the
passing switch is operated.
CAUTION
Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.
COMMENTS ON TROUBLE SYMPTOM

normal, the passing switch input signal 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
DIAGNOSTIC PROCEDURE
Step 1. Check that the headlamps operate.
Check that the low-beam and high-beam headlamps
work normally.
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Repair the headlamps. Refer to trouble
symptom chart
Step 2. Pulse check
Check the input signal from the passing switch.
