INSPECTION PROCEDURE D-5: The power window timer function does not work normally. <Vehicles for Argentina>
 CAUTION
 Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.
OPERATION
The ETACS-ECU operates this function in accordance with the input signals below.
  • Ignition switch (IG1)
  • Driver's door switch
COMMENTS ON TROUBLE SYMPTOM
If the power window timer function does not work normally, these input signal circuit(s), the power window main switch or the ETACS-ECU may be defective.
POSSIBLE CAUSES
  • Malfunction of the front door switch (LH)
  • Malfunction of the power window main switch
  • Malfunction of the ETACS-ECU
  • Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 1. Check the adjustment function.
Check that the power window timer function has been enabled by using the adjustment function.
Q: Is the check result normal?
YES:  Go to Step 2.
NO:  Enable the power window timer function by using the adjustment function. Refer to .
Step 2. ECU check by using the SWS monitor
Check that the power supply and earth lines to the ETACS-ECU and the power window main switch (power window module) and the SWS communication lines are normal.
  • Turn the ignition switch from the ON to the OFF position.
ECUS TO BE CHECKED
  • ETACS ECU
  • P/W MODULE
OK: "OK" are displayed for all the items
NOTE: "OK" is displayed for the power window switch (power window module) for approximately one minute, and then changed to "NG". However, only "OK" is displayed for the ETACS-ECU.
Q: Is the check result normal?
"OK" are displayed for all the items:  Go to Step 3.
"NG" is displayed on the "ETACS ECU" menu.:  Refer to Inspection Procedure A-3 "Communication with ETACS-ECU is not possible ."
"NG" is displayed on the "P/W MODULE" menu.:  Refer to Inspection Procedure A-5 "Communication with power window main switch (power window module) is not possible ."
Step 3. Function diagnosis by using the SWS monitor
Check the SWS communication signal, which are related to the power window timer function.

NOTE: For item No.33 "P/W SW ACCEPT", "PERMIT" is displayed for approximately 30 seconds after the ignition switch is turned off, and then change to "PROHIBIT". In addition, on item No.71 "P/W MODULE", "NORMAL ACK" is changed to "INPUT CHECK" momentarily, when the power window main switch is operated for approximately 30 seconds after the ignition switch is turned off.
OK: Normal conditions are displayed for all the items.
Q: Is the check result normal?
Normal conditions are displayed for all the items.:  Go to Step 4.
Normal condition is not displayed for item No.30:  Refer to Inspection Procedure P-2 "The ignition switch (IG1) signal is not received ."
Normal condition is not displayed for item No.33:  Replace the ETACS-ECU.
Normal condition is not displayed for item No.71:  Replace the power window main switch.
Step 4. Retest the system.
After the power window main switch is replaced, check that the power window timer function works normally.
  1. Replace the power window main switch.
  1. Check that the power window timer function works normally.
Q: Is the check result normal?
YES:  The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
