DTC Confirmation Procedure
Confirm that battery voltage is over 12 V before performing the following procedures.
Turn ignition switch to LOCK.
Connect X-431 3G diagnostic tester (the latest software) to Data Link Connector (DLC).
Turn ignition switch to ON.
Use X-431 3G diagnostic tester to record and clear the DTCs stored in the lighting system.
Turn ignition switch to LOCK and wait for a few seconds.
Turn ignition switch to ON and then select Read Code.
If DTC is detected, the malfunction indicated by the DTC is current. Go to the diagnosis procedure - Step 1.
If DTC is not detected, the malfunction indicated by the DTC is intermittent. Please refer to the Intermittent
DTC Troubleshooting.
Intermittent DTC Troubleshooting
If malfunction is intermittent, perform the followings:
Check if connectors are loose.
Check if wire harnesses are worn, pierced, pinched or partially broken.
Monitor X-431 3G diagnostic tester (the latest software) data that is related to this circuit.
Wiggle related wire harnesses and connectors and observe if signal is interrupted in the related circuit.
If possible, try to duplicate the conditions under which the DTC was set.
Look for the data that has changed or the DTC to be reset during the wiggle test.
Look for broken, bent, protruded or corroded terminals.
Inspect the mounting areas of headlight adjustment switch assembly and light assemblies and so on for
damage, foreign matter, etc. that will cause incorrect signals.
If multiple trouble codes were set, refer to the circuit diagrams to look for any common ground circuit or
power supply circuit applied to the DTC.
Refer to Technical Bulletin that is applied to the malfunction.
Ground Inspection
Groundings are very important to entire circuit system, which are normal or not can seriously affect the entire
circuit system. Ground points are often exposed to moisture, dirt and other corrosive environments. Corrosion
(rust) and oxidation may increase load resistance. This situation will seriously affect the normal operation of
the circuit.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can affect
the electronically controlled circuit. The operations to check the ground points are as follows:
1. Remove the ground bolt or nut.
2. Check all contact surfaces for tarnish, dirt and rust, etc.
3. Clean as necessary to ensure that contacting is in a good condition.
4. Reinstall the ground bolt or nut securely.

5. Check if add-on accessories interfere with the ground circuit.
6. If several wire harnesses are crimped into one ground terminal, check if they are installed correctly. Make
sure all wire harnesses are clean, securely fastened and providing a good ground path.
System Diagnosis
1. Description
a. Lighting system data and Diagnostic Trouble Codes (DTCs) can be read from the Data Link Connector
3 (DLC3) of vehicle. When system seems to be malfunctioning, use X-431 3G diagnostic tester to
check for a malfunction and perform repairs.
2. Check battery voltage
Standard Voltage: 11 to 14 V
If voltage is below 11 V, recharge or replace the battery before proceeding to next step.
DTC Check/Clear
1. Check DTCs
a. Connect X-431 3G diagnostic tester to Data Link Connector (DLC).
b. Turn ignition switch to ON, and turn X-431 3G diagnostic tester on.
c. Enter the following menus to read the current malfunction: T21/BCM/Read fault code/Read present
fault code.
d. Read DTCs.
2. Clear DTCs.
a. Connect X-431 3G diagnostic tester to Data Link Connector (DLC).
b. Turn ignition switch to ON, and turn X-431 3G diagnostic tester on.
c. Enter the following menus: T21/BCM/Erase fault code.
d. Clear the DTCs by following the indications on the tester screen.
Data List/Active Test
1. Read the Data List.
HINT:
Using the X-431 3G diagnostic tester Data List to perform Active Tests allows the values or states of
switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive
inspection can be very useful because intermittent problems or signals may be discovered before parts or
wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save
diagnostic time.
a. Connect X-431 3G diagnostic tester to Data Link Connector (DLC).
b. Turn ignition switch to ON, and turn X-431 3G diagnostic tester on.
c. Enter the following menus: T21/BCM/Read data strean/Input status (Light).
d. Read the Data List according to the display on the tester.
CAUTION
In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely
on these reference values when deciding whether a part is faulty or not.
