STEP 10. Check ETACS-ECU connector C-317 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connector C-317 in good condition?
YES : Go to Step 11.
NO : Repair the damaged parts.
STEP 11. Check the Wiring harness between ETACS-ECU
connector C-317 (terminal No. 2,9) and center panel unit
connector C-104 (terminal No. 15,12).
• Check the input/output lines for open circuit and short cir-
cuit.
Q: Is the check result normal?
YES : Go to Step 12.
NO : Repair the wiring harness between ETACS-ECU
connector C-317 and center panel unit connector
C-104.
STEP 12. Retest the system.
Q: Does the theft-alarm work normally?
YES : The trouble can be an intermittent malfunction (Refer
to GROUP 00, How to use
Troubleshooting/inspection Service Points
− How to
Cope with Intermittent Malfunction
NO : Replace the ETACS-ECU.
Inspection Procedure 2: The interior alarm does not work normally while the theft-alarm is triggered.
CAUTION
Before replacing the ECU, ensure that the power
supply circuit, the ground circuit and the com-
munication circuit are normal.
.
TECHNICAL DESCRIPTION (COMMENT)
If the interior alarm does not work normally, the input
signal circuits to the components below,
ETACS-ECU, or combination meter built-in tone
alarm may have a problem.
.
TROUBLESHOOTING HINTS
• The ETACS-ECU may be defective
• Combination meter may be defective
• The wiring harness or connectors may have
loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector
