WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: PRECAUTION

1. NOTICE FOR INITIALIZATION

NOTICE:
When disconnecting the cable from the negative (-) battery terminal, initialize the following systems after the cable is reconnected.





2. PRECAUTIONS WHEN USING TECHSTREAM

(a) When using the Techstream with the power switch off to troubleshoot: Connect the Techstream to the vehicle, and turn a courtesy light switch on and off at 1.5 second or less intervals until communication between the Techstream and vehicle begins.

(b) After all DTCs are cleared, check if the trouble occurs again 6 seconds after turning the power switch on (IG).

3. POWER WINDOW CONTROL SYSTEM PRECAUTIONS

CAUTION:
* The power window control system uses a LIN communication system. 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.
* The power window control system prohibits the auto up and down function when the jam protection function malfunctions. Therefore, troubleshoot the power window control system after confirming that no trouble codes are output.
* If the power window regulator motor assembly has been replaced with a new one, initialize the power window control system.
* If the power window regulator motor assembly and door window regulator sub-assembly have been removed and installed, or if the power window regulator motor assembly was reused when a door glass or door glass run was replaced, initialize the power window control system.
* The jam protection function may operate unexpectedly even when the power window control system is normal due to detection of a value different from the operation learned value when the door glass moving speed changes sharply under any of the following conditions:
(1) A power window is being opened or closed while the vehicle is driven on a rough road.
(2) A power window is being opened or closed while the door is being opened or closed.
(3) The voltage changes abruptly.
NOTICE:
Do not disconnect the auxiliary battery while the power switch is on (IG). Otherwise, DTC B2313 will be output.
