Diagnosis Tools
X-431 3G Diagnostic Tester
When connecting the X-431 3G diagnostic tester:
Connect the X-431 3G diagnostic tester (the latest software) to the Data Link Connector (DLC) for
communication with vehicle.
DLC is located on the driver side instrument panel crossmember.
DLC uses a trapezoidal design which can hold 16 terminals.
Digital Multimeter
When using the digital multimeter:
Troubleshoot the electrical malfunctions and wire harness system.
Look for the basic fault.
Measure the voltage, current and resistance.
DTC Confirmation Procedure
Confirm that the battery voltage is normal before performing the following procedures.
Turn ignition switch to LOCK.
Connect the X-431 3G diagnostic tester (the latest software) to the Data Link Connector (DLC), and make
it communicate with the vehicle electronic module by data network.
Turn ignition switch ON.
Using the X-431 3G diagnostic tester to record and clear the DTCs stored in Body Control Module (BCM).
Turn ignition switch to LOCK and wait for a few seconds.
Turn ignition switch 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 no DTC is detected, the malfunction indicated by the DTC is intermittent. Please refer to the Intermittent
DTC Troubleshooting.

Intermittent DTC Troubleshooting
If the malfunction is intermittent, perform the followings:
Check if connectors are loose.
Check if wire harnesses are worn, pierced, pinched or partially broken.
Wiggle the related wire harnesses and connectors and observe if the 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 wiper motor assembly, wire harness or wire harness connector and so on for
damage, foreign matter, etc. that will cause incorrect signals.
Check and clean all the wire harness connectors and grounding parts related to the current DTC.
Remove the Body Control Module (BCM) from the malfunctioning vehicle and install it to a new vehicle and
perform a test. If the DTC cannot be cleared, the Body Control Module (BCM) is malfunctioning. If the DTC
can be cleared, reinstall the Body Control Module (BCM) to the original vehicle.
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 the Technical Bulletin that is applied to the malfunction.
Ground Inspection
Ground points are very important to the entire circuit system, and the grounding condition can seriously affect
the entire circuit system. Ground points are often exposed to moisture, dirt and other corrosive environments.
Corrosion (rust) and oxidation can increase load resistance. This situation will seriously affect the normal
operation of circuit. Operations to check the ground points are as follows:
1. Remove the ground bolt or nut.
2. Check all the matching surfaces for tarnish, dirt, rust, etc.
3. Clean as necessary to ensure that the contacting is in a good condition.
4. Reinstall the ground bolt or nut securely.
5. Check if the 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 the wire harnesses are clean, securely fastened and providing a good ground path.
Diagnosis Procedure
HINT:
Use the following procedures to troubleshoot the wiper and washer systems.
Standard voltage: 11 to 14 V
If the voltage is below 11 V, recharge or replace the battery before proceeding to next step.
