STEP 21. Check the wiring harness from the F-04 
<vehicles with rear body> or F-23 <vehicles 
without rear body> rear combination lamp (turn: 
LH) or F-02 <vehicles with rear body> or F-19 
<vehicles without rear body> rear combination 
lamp (turn: RH) connector terminal No.1 to C-218 
ETACS-ECU connector terminal No.3 or No.4.

NOTE: 

Prior to the wiring harness inspection, check interme-
diate connector F-07 and C-31 <RHD>, junction 
block connector C-221 <LHD> or C-204 <RHD>, and 
repair if necessary.

• Check the output lines for open circuit.

Q: Is the check result normal?

YES : 

Go to Step 22.

NO : 

Repair the wiring harness. Go to Step 23.

STEP 22. Retest the system.
Check that the rear turn-signal lamps illuminate nor-
mally.

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 

Malfunction ). Go to Step 23.

NO : 

Replace the rear combination lamp. Go to 
Step 23.

STEP 23. Check whether the diagnosis code is 
reset.
Check if diagnosis code No.B1707 is set to the 
ETACS-ECU.

Q: Is the diagnosis code set?

YES : 

Replace the ETACS-ECU and register the 

ID codes (Refer to 

P.54A-39

).

NO : 

The procedure is complete.

Code No.L0432 RLS RS adaptation error

DIAGNOSTIC FUNCTION
When the lighting control sensor is installed with the 
wrong procedure, code No. L0432 is stored by LIN.

COMMENTS ON TROUBLE SYMPTOM
The lighting control sensor may have been installed 
with the wrong procedure.

• Incorrect installation procedure: Connect the con-

nector before mounting the lighting control sensor 
onto the optical coupler of the windshield. 

• Correct installation procedure: Mount the lighting 

control sensor onto the optical coupler of the 
windshield. Wipe the windshield surface thor-
oughly, and check that the surface is dry. Then, 
connect the connector.

PROBABLE CAUSES

• Lighting control sensor improperly installed

• Lighting control sensor (rain sensor) abnormal 

operation

DIAGNOSIS PROCEDURE

STEP 1. Check whether the diagnosis code is 
reset.
Disconnect the connector from the lighting control 
sensor, and connect the connector to the lighting 
control sensor again. Then, check again if the diag-
nosis code is set to LIN.
(1) Disconnect the connector of lighting control 

sensor, and connect it again.
NOTE: When connecting the connector, follow 
the correct installation procedure.

(2) Turn the ignition switch from "LOCK" (OFF) 

position to "ON" position.

(3) Check if diagnosis code is set.

Q: Is the diagnosis code set?

YES : 

Go to Step 2.

NO : 

The lighting control sensor is installed with 
the wrong procedure.

STEP 2. Lighting control sensor installation 
surface check
Visually check the presence of scratches or air bub-
bles (diameter of 5 mm or more) on the windshield to 
which the lighting control sensor is installed. In addi-
tion, visually check that the optical coupler is not bro-
ken and that the lighting control sensor can be 
installed. 

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Replace the windshield (Refer to GROUP 
42 

− Windshield )

STEP 3. Check whether the diagnosis code is 
reset.
Check again if the diagnosis code is set to LIN.
(1) Wipe the windshield surface of the lighting control 

sensor section thoroughly, and check that the 
surface is dry. Then, perform the lighting control 
sensor (rain sensor) adaptation. <Refer to 
GROUP 51 

− Lighting Control Sensor (Rain 

Sensor) Adaptation >.

(2) Turn the ignition switch from "LOCK" (OFF) 

position to "ON" position.

(3) Check if diagnosis code is set.

Q: Is the diagnosis code set?

YES : 

Replace the lighting control sensor.

NO : 

The trouble can be an intermittent 
malfunction (Refer to GROUP 00 

− How to 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction ).

Code No.L0434 RLS rain sensor error

 

Code No.L0436 RLS light sensor error

DIAGNOSTIC FUNCTION
If a trouble occurs in the lighting control sensor, code 
Nos. L0434 and L0436 are stored to LIN.

PROBABLE CAUSE
Malfunction of the lighting control sensor

DIAGNOSIS PROCEDURE

Check whether the diagnosis code is reset.
Check again if the diagnosis code is set to LIN.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from "LOCK" (OFF) 

position to "ON" position.

SYMPTOM PROCEDURES

Inspection Procedure 1: None of the low-beam headlamps illuminate.

CAUTION

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

COMMENTS ON TROUBLE SYMPTOM
If none of the low-beam headlamps illuminate, the 
headlamp switch input circuit, the headlamp relay 
(LO) or the ETACS-ECU may be defective.
