DIAGNOSIS & TESTING

Problem Symptoms Table

HINT:
Use the table below to help determine the cause of the problem. Check each suspected area in order. Repair 
or replace the faulty components, or adjust as necessary.

Diagnosis Tools

X-431 3G Diagnostic Tester

When connecting X-431 3G diagnostic tester:
 Connect X-431 3G diagnostic tester (the latest software) to Data Link Connector (DLC) for communication 

with vehicle.

 DLC is located at the driver side instrument panel crossmember.
 DLC uses a trapezoidal design which can hold 16 terminals.

Digital Multimeter

When using digital multimeter:
 Troubleshoot electrical malfunctions and wire harness system.
 Look for basic fault.
 Measure voltage, current and resistance.

DTC Confirmation Procedure

Confirm that battery voltage is normal before performing the following procedures.
 Turn ignition switch to LOCK.
 Connect X-431 3G diagnostic tester (the latest software) to Data Link Connector (DLC), and make it 

communicate with vehicle electronic module by the data network.

 Turn ignition switch to ON.

 Using X-431 3G diagnostic tester to record and clear the DTCs stored in the Body Control Module (BCM).
 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 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.
 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 power window assembly, wire harness or wire harness connector and so on 

for damage, foreign matter, etc. that will cause incorrect signals.

 Check and clean all 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 DTC cannot be cleared, the Body Control Module (BCM) is malfunctioning. If DTC can be 
cleared, reinstall the Body Control Module (BCM) to 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 Technical Bulletin that is applied to the malfunction.

Ground Inspection

Grounding 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. 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.

Diagnosis Procedure

HINT:
Use the following procedures to troubleshoot the power window control system.

Standard voltage: 11 to 14 V
If the voltage is below 11 V, recharge or replace the battery before proceeding to next step.
