2.PRECAUTIONS WHEN USING INTELLIGENT TESTER
  1. When using the intelligent tester to troubleshoot the LIN communication line: Connect the intelligent tester to the vehicle, and turn the courtesy light switch on and off at 1.5 second intervals until communication between the tester and vehicle begins.

  2. After all DTCs are cleared, check if the trouble occurs again 6 seconds after the ignition switch is turned on (IG).


3.POWER WINDOW CONTROL SYSTEM PRECAUTIONS

NOTICE:
  1. The power window control system uses a multiplex communication system (LIN). Inspect the communication function by following HOW TO PROCEED WITH TROUBLESHOOTING. Troubleshoot the power window control system after confirming that the communication system is functioning properly.
  2. The power window control system prohibits the AUTO UP / DOWN function when the jam protection function malfunctions. Therefore, troubleshoot the power window control system after confirming that no diagnostic codes are displayed.
  3. When the front door window regulator (on the driver side) or the power window regulator motor assembly (on the driver side) is replaced, the power window control system must be initialized (Click here).
  4. After a door glass or a door glass run has been replaced, the jam protection function may operate unexpectedly when the AUTO UP function is used. In such cases, the AUTO UP function can be resumed by repeating the following operation at least 5 times:
    1. Close the power window by fully pulling up the power window switch and holding it at the AUTO UP position.
    2. Open the power window by fully pushing down the switch.
  5. The jam protection function may operate unexpectedly even when the power window control system is normal, due to detection of the different operation learned value when the door glass moving speed changes sharply under any of the following conditions:
    1. A power window being opened or closed while the vehicle is running on a rough road.
    2. A power window being opened or closed while the door is being opened or closed.
    3. A sharp voltage change.
  6. Do not disconnect the battery while the ignition switch is on (IG). Otherwise DTC B2311 will be output.
