54C-184
INSPECTION PROCEDURE L-4: The turn-signal indicator lamp does not illuminate.
CAUTION
Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.
COMMENTS ON TROUBLE SYMPTOM
If the turn-signal indicator lamp does not illuminate
normally, connector(s), wiring harness in the CAN
bus lines, the ETACS-ECU or the combination meter
may be defective.
POSSIBLE CAUSES
• Malfunction of the ETACS-ECU
• Malfunction of the combination meter
• Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 1. Check that the hazard warning lamps
operate.
Check that the hazard warning lamps illuminate nor-
mally.
Q: Is the check result normal?
YES :
Go to Step2.
NO :
Refer to Inspection Procedure L-2 "The
hazard warning lamps do not illuminate
normally
."
Step 2. M.U.T.-III CAN bus diagnostics
Use the M.U.T.-III to diagnose the CAN bus lines.
Q: Is the check result normal?
YES :
Go to Step3.
NO :
Repair the CAN bus line (Refer to GROUP
54D, Diagnosis
).
Step 3. M.U.T.-III other system diagnosis code.
Check whether the combination meter-related diag-
nosis code is set.
Q: Is the diagnosis code set?
YES :
Diagnose the combination meter (Refer to
GROUP 54A
− Troubleshooting
NO :
Go to Step 4.
Step 4. ECU check by using the SWS monitor
Check that the power supply and earth lines to the
ETACS-ECU and the SWS communication lines are
normal.
• Ignition switch: OFF
ECU TO BE CHECKED
• ETACS ECU
OK: "OK" is displayed on the "ETACS ECU"
menu.
Q: Is the check result normal?

Step 5. M.U.T.-III actuator test
Perform the actuator test for the combination meter,
and check that the turn-signal indicator lamps illumi-
nate (Refer to GROUP 54A
− Combination Meter
).
Q: Is the check result normal?
YES :
Replace the ETACS-ECU.
NO :
Replace the combination meter.
INSPECTION PROCEDURE L-5: The turn-signal lamps do not illuminate when the ignition switch is at
the ACC position.
CAUTION
Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.
COMMENTS ON TROUBLE SYMPTOM
If the turn-signal lamps do not illuminate with the igni-
tion switch at ACC, the input signal circuit from the
ignition switch (ACC) may be defective or the SWS
monitor customisation function has set "TURN-SIG-
NAL" to "IG-ON".
POSSIBLE CAUSES
• Malfunction of the column switch
• Malfunction of the ETACS-ECU
• Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 1. Customize function by using the SWS
monitor
Use the SWS monitor customisation function to con-
firm that "TURN-SIGNAL" is set to "IG-ACC."
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Use the SWS monitor customisation
function to set "TURN-SIGNAL" to
"IG-ACC." Refer to
.
Step 2. Check that the turn-signal lamps operate.
Check that the turn-signal lamps illuminate normally
when the ignition switch is turned to the ON position.
Q: Is the check result normal?
YES :
Go to Step 3.
NO :
Refer to Inspection Procedure L-1 "The
turn-signal lamps do not illuminate normally
."
Step 3. SWS monitor data list
Check the ETACS-ECU signals which are related to
the turn-signal lamp illumination when the ignition
switch is at the ACC position.
<Selected item> ETACS-ECU
• Ignition switch: ACC position
OK: Normal condition is displayed.
Q: Is the check result normal?
YES :
Go to Step 4.
NO :
Refer to inspection procedure N-1 "The
Ignition switch (ACC) signal is not received
."
Step 4. Retest the system.
Check whether the turn-signal lights illuminate.
Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00
− How to
use Troubleshooting/inspection Service
Points
− How to Cope with Intermittent
).
NO :
Replace the ETACS-ECU.

INTERIOR LAMP
INSPECTION PROCEDURE M-1: The interior lamps (room ramp, luggage compartment lamp) does not
illuminate or extinguish normally.
CAUTION
Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.
COMMENTS ON TROUBLE SYMPTOM
The ETACS-ECU operates the interior lamps (room
lamp, luggage compartment lamp) in accordance
with the input signals below.
• Ignition switch (IG1)
• Key reminder switch
• All of the door switches
• Driver's door lock actuator
If this function does not work normally, these input
signal circuit(s) or the ETACS-ECU may be defec-
tive. Alternatively, it is possible that "RM LMP TN
OFF" was set to "W/O FUNCTION" by using the
SWS monitor customisation function.
POSSIBLE CAUSES
• Malfunction of the key reminder switch
• Malfunction of the door switches
• Malfunction of the driver's door lock actuator
• Malfunction of the ETACS-ECU
• Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 1. Customize function by using the SWS
monitor
Use the SWS monitor customisation function to con-
firm that "RM LMP TN OFF" is set to "7.5s", "15s",
"30s" or "60s".
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Use the SWS monitor customisation
function to set "RM LMP TN OFF" to "7.5s",
"15s", "30s" or "60s". Refer to
