• In troubleshooting, confirm that the problem symptoms have been accurately identified. Preconceptions should be discarded in order to make an accurate judgment. To clearly understand what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time the malfunction occurred.
• Gather as much information as possible for reference. Past problems that seem unrelated may also help in some cases.
• The following 5 items are important points in the problem analysis:

  What	Vehicle model, system name
  When	Date, time, occurrence frequency
  Where	Road conditions
  Under what conditions?	Driving conditions, weather conditions
  How did it happen?	Problem symptoms

1. Measure the auxiliary battery voltage with the power switch off.

   Standard Voltage

   11 to 14 V

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

2. Check the fuses and relays.
3. Check the connector connections and terminals to make sure that there are no abnormalities such as loose connections, deformation, etc.

See step  10

1. If any of the door window regulators, power window regulator motor assemblies, door glass or door glass runs have been removed and reinstalled, perform "Initialize Power Window Control System" (initialization of the pulse sensor) for the applicable door glass (See article. Refer to INITIALIZATION [08/2014 - 08/2015] Refer to INITIALIZATION [08/2015 - ] ).

   HINT: 

   If "Initialize Power Window Control System" (initialization of the pulse sensor) has not been performed, the auto operation function, jam protection function, key-linked operation function*, wireless transmitter-linked operation function* and key-off operation function will not operate or will operate incorrectly.

   *: This function is set through the customize function, as it is off by default.
