NOTE:
Prior to the wiring harness inspection, check interme-
diate connector C-12 <tailgate> and junction block
connector B-23 or B-24 <RH> and repair if neces-
sary.
• Check the input line for open circuit.
Q: Is the check result normal?
YES :
Go to Step 7.
NO :
Repair the wiring harness between each of
the door switches and the ETACS-ECU.
Step 7. ETACS switch data by using the SWS
monitor
Check the input signals from the door switches.
• Doors other than the driver's door: Closed to
open
OK: Normal condition is displayed.
Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00
