If this function does not work normally, these input
signal circuit(s) or the ETACS-ECU may be
defective. Note that this function can be
disabled/enabled by the customize function (default
setting; enabled). In order to change the setting, the
SWS monitor is required.
POSSIBLE CAUSES
• Malfunction of the door switches
• Malfunction of the ETACS-ECU
• Damaged harness wires and connectors
DIAGNOSTIC PROCEDURE
Step 1. Customize function by using the SWS
monitor
Use the SWS monitor customisation function to
confirm that "DOOR WARN BUZ" is set to other than
"W/O FUNCTION" (one of the settings below).
